333: I Used To Do a Podcast

00:00SPEAKERNorm, I really enjoyed Project Hail Mary when I read it a hundred years ago, but I don't

00:09SPEAKERknow that I'm going to get to a movie theater to see it.

00:13SPEAKERAm I making a mistake?

00:14SPEAKERHow bad a mistake am I making?

00:16SPEAKERYou're making a pretty big mistake.

00:17SPEAKERI guess it really depends on the size of the mistake is you can measure it with the size

00:21SPEAKERof the screen you're missing out on.

00:23SPEAKERWe have the giant Metreon here, which is probably where I'd either go see it there or the Dolby.

00:28SPEAKERSo as we're recording this, all the PLF screens, the premium large format screens have been

00:34SPEAKERtaken over by Super Mario Galaxy, the review proof, Super Mario Galaxy.

00:39SPEAKERSo unfortunately, as of right now, your options to watch Project Hail Mary in theaters is

00:45SPEAKERlimited, but, but, but, but, but, but it will be back in IMAX at the Metreon April 17th

00:54SPEAKERto the 22nd.

00:55SPEAKEROkay, and Will, you must make the appointment to see it.

00:59SPEAKEROkay.

01:00SPEAKERIs the best row.

01:01SPEAKEROkay.

01:02SPEAKEROkay.

01:03SPEAKER16 K 16 is my, I will, I will give up, I know your ways, I know your ways.

01:06SPEAKERI've been, I've been to the IMAX with you.

01:07SPEAKERI've seen, I've seen many transformers movies that IMAX with you over the years.

01:11SPEAKERThey were all bad.

01:12SPEAKERYou know, I, I, I, over the years I've moved on one row.

01:16SPEAKERI used to be row L for further back, but now for increased immersion, I've moved down and

01:22SPEAKERforward one row K 16 at the Metreon.

01:26SPEAKERWe're all a little older now and maybe our eyes aren't working quite as well.

01:29SPEAKERThat extra row helps, you know, you need that extra, that extra space.

01:33SPEAKERDo they do 3d stuff with that or is it just, is it just shot in IMAX?

01:37SPEAKERThis one, Oh, you're, you're, you're opening the can.

01:41SPEAKERThis one is shot for IMAX and shot for IMAX quote unquote is a program that IMAX has to

01:47SPEAKERcertify films to be an IMAX, but this one is special because this one, it doesn't, it

01:52SPEAKERwasn't filmed with IMAX film cameras.

01:56SPEAKERAll of those were used, you know, for the Odyssey and especially the new one that you

02:01SPEAKERI think there'll be talking more about soon, but this one was shot with a large, large

02:07SPEAKERformat or, you know, medium format Alexa camera that the cinematographer Craig Frazier use

02:17SPEAKERa special anamorphic lens to compress it, the two by one aspect ratio of the sensor

02:24SPEAKERto 1.4, three of the IMAX aspect ratio.

02:30SPEAKERSo they're doing an anamorphic squeeze, basically squeeze as opposed to top down.

02:34SPEAKERNormally the squeeze would be top down.

02:36SPEAKERThis is squeezed side to side, so you don't have to, there was no pillar boxing, you know,

02:41SPEAKERno cropping in the edges technically of the frame, the left and right sides have more

02:47SPEAKERdata than the top and bottom.

02:49SPEAKERAnd that's why the lens flares, when you see the film are vertical, not horizontal anamorphic

02:55SPEAKERlens flares.

02:56SPEAKERAll that to say is they had IMAX in mind and this was printed in 70 millimeter.

03:04SPEAKERSo at the lucky locations, I think there are, you know, a couple dozen IMAX cinemas around

03:11SPEAKERthe world that still have the film projectors.

03:15SPEAKERThis one, we at the Metreon have a real IMAX, like, you know, 87 foot screen.

03:21SPEAKERThey have the dual film projectors that give you the brightness or dual laser projectors

03:25SPEAKERthat give you the brightness as well as the full 70 millimeter film projector.

03:29SPEAKERAnd so we've been lucky to know last year we got sinners, we got one about another,

03:32SPEAKERwhich is the full aspect ratio of the whole movie.

03:35SPEAKERAnd this one, it's not a spoiler to say that the space scenes, all of the scenes are off

03:40SPEAKERearth are in full aspect ratio and everything that's on earth, the memories, the flashbacks

03:46SPEAKERare standard scope.

03:49SPEAKERChud film.

03:50SPEAKERYeah.

03:51SPEAKERWith, with the, the, the top and bottom.

03:53SPEAKEROkay.

03:54SPEAKEROkay.

03:55SPEAKERLook, you've almost convinced me.

03:56SPEAKERThe only problem now is, man, go into the Metreon.

03:59SPEAKERIt's like, if I go with, with the, with the whole fam, it's like a cool hundred, 150 bucks

04:05SPEAKERnow.

04:06SPEAKERCause it's like tickets, parking, snacks, the whole thing.

04:08SPEAKER$24 parking.

04:09SPEAKERAre you not, are you not an A-list member?

04:11SPEAKERNo.

04:12SPEAKERAre you not on the AMC Stubbs A-list, one of the coolest, coolest clubs in America,

04:18SPEAKERaccording to Bloomberg?

04:19SPEAKERLook, I used to do a podcast.

04:20SPEAKERI used to do a podcast and then I was on the A-list and these days, not so much.

04:25SPEAKERSo

04:53SPEAKERWelcome to Brad and Will Made a Tech Pod I'm Will, Norm's here.

04:57SPEAKERI'm here.

04:58SPEAKERBrad's out.

04:59SPEAKEROh man.

05:00SPEAKERWhy am I here then?

05:01SPEAKERI was here to hang out with Brad.

05:02SPEAKERI know.

05:03SPEAKERI'm sorry.

05:04SPEAKERThank you for coming on.

05:05SPEAKERBrad's out doing some medical stuff this week, but Norm graciously decided, stepped in, took

05:11SPEAKERthe call when I said, Hey man, I have your dog, by the way, she's great.

05:16SPEAKERI got morning snuggles with the doggo.

05:18SPEAKERI need proof of life.

05:20SPEAKERYou know, I, we had an earthquake last night.

05:22SPEAKERYeah.

05:23SPEAKERIt was 2 a.m.

05:24SPEAKERAnd the thing I did not have was the warm body of this half pig, half dog.

05:29SPEAKERSo hold on to.

05:30SPEAKERYeah.

05:31SPEAKERShe was out with my wife in the living room who had fallen asleep on the sofa like three

05:33SPEAKERhours earlier and didn't wake up during the earthquake.

05:36SPEAKERSo when I asked her this morning, I was like, Hey, did you feel the earthquake?

05:39SPEAKERShe was like, no, man.

05:40SPEAKERI was awake.

05:41SPEAKERI was something I was scrolling my phone.

05:42SPEAKERI was doing the whole, I was doing laundry and I was like, you would have felt this one

05:45SPEAKERman.

05:46SPEAKERCause like it woke me up from a deep sleep.

05:49SPEAKERI was full on.

05:50SPEAKERI didn't jump out of bed because I've lived here long enough.

05:53SPEAKERI don't do that anymore.

05:54SPEAKERI just lay there and wait for the end.

05:56SPEAKERBut but yeah, the full, full like wake up from the deep sleep and still had time to

06:01SPEAKERexperience some and then posted earthquake on blue sky and then immediately went right

06:06SPEAKERback to sleep, which is like, you know?

06:07SPEAKERYeah.

06:08SPEAKERPerfect.

06:09SPEAKERThe way to do it, the way to do it.

06:10SPEAKERBut we're normally here this week to talk about something that you, you and I started

06:16SPEAKERon a path with this like 15, 16 years ago, actually 16 years ago about now, if I recall

06:23SPEAKERI think we built the first cupcake in April or may of 2020 2010, a hundred years ago.

06:28SPEAKERAnd you, you've stuck with it way longer than I did because I, I got annoyed about 10 years

06:33SPEAKERago and just stopped 3d printing stuff entirely.

06:37SPEAKERJust about the time things started getting good.

06:38SPEAKERIt seems like, so you're going to give us a kind of state of the union, a primer on

06:43SPEAKERwhat the 3d 3d printer market is like these days as somebody who reviews a fair number

06:47SPEAKERof printers still.

06:48SPEAKERRight?

06:49SPEAKERYeah.

06:50SPEAKERWow.

06:51SPEAKERI mean, we, we, we went through the hard times and you're missing out on the good times.

06:54SPEAKERI, I'm going to go and tell you, I have, I've been looking again, like, well, like honestly

07:00SPEAKERwhen micro center opened and I started looking at what you can do with the kind of printers

07:03SPEAKERthat they're selling at a store that you can go to, I was like, Oh, this, this is, this

07:08SPEAKERis a thing.

07:09SPEAKERAnd then I started following some 3d printer people, like people who design stuff who like

07:14SPEAKERhave YouTube channels that are about designing stuff, but also they sell the models and you

07:18SPEAKERcan like join their Patrion to get the models and all that stuff.

07:21SPEAKERAnd I started following a couple of them and I'm like, Oh, we've moved, we moved into the

07:25SPEAKERtime when like, yes, I would buy this planter that this guy has designed that lives on a

07:29SPEAKERdowel.

07:30SPEAKERRight.

07:31SPEAKERThat's a cool planner.

07:32SPEAKERI would put that in my office.

07:33SPEAKERThat looks nice.

07:34SPEAKERAnd, and we've, we've reached a time where it seems much more useful.

07:36SPEAKERSo is it correct or not?

07:39SPEAKERAre you still pretty much tickets and yeah, it's supposed to trick it.

07:42SPEAKERBut like, I think everything around the ecosystem of 3d printing has converged to a point where

07:49SPEAKERit just, the dream that, you know, the people who started rep rap is really fulfilled.

07:54SPEAKERThese are appliances now.

07:55SPEAKERThey are term key appliances that you can go to a best buy and best buy has like ads

08:00SPEAKERfor how to use entry-level 3d printers and can buy a reliable 3d printer that you can

08:06SPEAKERbring home to a your family, put in the home office and their ecosystems of files, their

08:15SPEAKERcommunities and their tools for you to generate your own your own models.

08:20SPEAKERAnd it all is so much easier.

08:22SPEAKERAnd there's, you're spending 95% of the time 3d printing and the 5%, not even like repairing

08:29SPEAKERthe printer, but like, you know, tinkering.

08:31SPEAKERYeah.

08:32SPEAKERSee back, back when I finally reached my limit, when I was, I think, I think I was still doing

08:37SPEAKERthe print of the week and it became like, it was that, that whole thing was supposed

08:42SPEAKERto be like something I could hit the button on and then leave and come back 10 hours later

08:47SPEAKERand redone.

08:48SPEAKERAnd it would never ever was that it was always like, do it.

08:53SPEAKERYou start it, you stop it, you start it, you start it, you know, and it ended up being

08:55SPEAKERa lot of fiddling.

08:56SPEAKERAnd it seems like between like self-leveling beds and like the surfaces that the, that

09:02SPEAKERthe plastic sticks to and all the different stuff that's going on, it seems much, much

09:07SPEAKERmore turnkey now.

09:08SPEAKERYep.

09:09SPEAKERYep.

09:10SPEAKERYou know, that's just a little bit of their speed so much faster now, you know, the, the

09:15SPEAKERvariety of materials of hotends and all of these are interchangeable.

09:20SPEAKERThe printers are modular themselves and there's still a lot of fundamental shared technologies,

09:25SPEAKERbut what do you want to start?

09:26SPEAKERCause we're talking primarily FDM right now, right?

09:28SPEAKERYeah.

09:29SPEAKERI mean, I wanted to, I wanted, I think we have a, like the overview of the market is

09:32SPEAKERthat there's a couple of different technologies.

09:35SPEAKERIt seems like the interesting stuff is happening in FDM again.

09:38SPEAKERLike there were a couple of years there where resin, where the resin ULB printers got pretty

09:43SPEAKERexciting, but, but like, what are you like if somebody comes up to you at, at a school

09:48SPEAKERevent and is like, Hey, you're the 3d printer guy, can you explain 3d printers to me?

09:52SPEAKERLike I want to get a 3d printer.

09:54SPEAKERWhat do you tell them?

09:55SPEAKERDo you tell them like, where do you start?

09:57SPEAKERIf they want, I guess if you want to spend $250 on a 3d printer right now, you can get

10:02SPEAKERa bamboo lab, a one mini, and that is a great printer to start with kids with a relatively

10:10SPEAKERsmall build area and build volume.

10:14SPEAKERAnd that one, that one will get, get it done for all your small trinkets and, and it can

10:19SPEAKERdo multicolor.

10:20SPEAKERSo, but that's, that's like on the low end, the entry level, I really depends on, I guess

10:24SPEAKERthe price range, right?

10:25SPEAKERLike, are you telling people, you're telling you you're, you're seeing people to FDM now,

10:29SPEAKERright?

10:30SPEAKERNot like, Oh yeah.

10:31SPEAKEROh yeah, yeah, yeah.

10:32SPEAKERLike I think between like 2020 and 2023 resin like exploded because of how affordable got

10:39SPEAKERand we covered the early resin printers too, right?

10:41SPEAKERThe first form labs and their SLA had been in the realm of like industrial printers for

10:47SPEAKERa long time.

10:49SPEAKERAnd it just became commoditized where these companies like Anycubic and Elegoo would pump

10:55SPEAKERout, literally pump out like six printers a year of various build volumes and that stabilized.

11:01SPEAKERI think they're in like their fifth generation of those printers now and resin is way more

11:08SPEAKERtoxic.

11:09SPEAKERI mean, you get crazy amount of fidelity in terms of layer heights and just the resolution

11:13SPEAKERof the print.

11:14SPEAKERSo for some specific communities like miniatures, it's really awesome for that.

11:20SPEAKERBut FDM just in that 2024 era when bamboo lab put out the X one carbon things just changed

11:29SPEAKERcompletely and now FDM is the way to go.

11:31SPEAKERWe should take a step back.

11:32SPEAKERFDM is fused deposition models, modeling, and resin printers, we're talking about resin

11:39SPEAKERprinters.

11:40SPEAKERWe're talking about resin that's activated with UV light.

11:43SPEAKERSo it's like a liquid material lithography.

11:45SPEAKERYeah.

11:46SPEAKERYeah.

11:47SPEAKERYeah.

11:48SPEAKERSo fundamentally like the way I would tell like a teenager is that, you know you're turning

11:53SPEAKERa digital object into a physical object and the digital object you can think of as a 3d

11:59SPEAKERmodel has a dimension.

12:01SPEAKERSo like you can, you can think about a cube or any type of shape that's in 3d and in all

12:07SPEAKERtypes of 3d printing that work today, the way that that digital object gets turned to

12:13SPEAKERa physical object is that you slice it into layers.

12:17SPEAKERSo you're literally turning the 3d device into a series of two 2d planes.

12:21SPEAKERExactly.

12:22SPEAKERExactly.

12:23SPEAKERSo you can think of how many layers it really is kind of up to you and up to the fidelity

12:27SPEAKERof the printer and the size of the thing you want to make.

12:31SPEAKERBut the software that turns the 3d model into basically 2d planes and then here is where

12:37SPEAKERyour paths open and how those 2d planes, how these cross sections of the 3d model get then

12:44SPEAKERmanifested into plastic.

12:47SPEAKERYou can choose between a couple of different techniques.

12:50SPEAKEREven when you're talking about since our nylon or censored metal, it's all fundamentally

12:55SPEAKERthe same process.

12:56SPEAKER3d printing is just layering on slices of shapes that then together become a large volumetric

13:05SPEAKER3d shape.

13:06SPEAKERIt's like that scene from resident evil, but backwards.

13:09SPEAKERYeah.

13:10SPEAKERThat was more of a grid.

13:11SPEAKERRight?

13:12SPEAKEROh yeah.

13:13SPEAKERI guess it was a grid.

13:14SPEAKERI'm thinking maybe I'm thinking about the cell.

13:15SPEAKERI think it's the cell, right?

13:17SPEAKERYeah.

13:18SPEAKERThree body problem, right?

13:19SPEAKERYeah.

13:20SPEAKERSo with FDM, it's it's, it's like a nozzle, right?

13:26SPEAKERIt's rolls of plastic that get melted through a heating element and extruded, meaning just

13:33SPEAKERpushed out of a tube and the nozzle is kind of like, it's a, you know, it's like the equivalent

13:40SPEAKERof going to a soft serve machine, you know, and pulling the tube and you are kind of drawing

13:47SPEAKERthe shape with layer by layer, line by line of melted plastic and that's basically it.

13:55SPEAKERAnd you know, these are like, as we did that video way back in 2010, these are fundamentally

14:00SPEAKERstill, you know, computer numerical numerical control.

14:03SPEAKERIt's still code that tells a series of motors how to move a, a print head across 3d space,

14:11SPEAKERX, Y, Z space.

14:13SPEAKERAnd so there are motors that then that move it, you know, in X, Y, Cartesian space.

14:18SPEAKERAnd in a line with another motor that extrudes the plastic layer by layer, you get something

14:24SPEAKERthat can take, you know, in the old days, days to make.

14:27SPEAKERAnd now with the faster machines and the faster motors and the optimized algorithms can take

14:33SPEAKERjust hours to make.

14:34SPEAKERYeah.

14:35SPEAKERIt's something I think I didn't understand when we were starting out for sure.

14:38SPEAKERAnd also there was, there wasn't really a lot of choice in the slicer world at the time.

14:43SPEAKERBut I didn't really appreciate how important the slicer was and how, you know, it's not

14:50SPEAKERlike a printer, a 2d printer, a paper printer where like the, the thing that the world,

14:57SPEAKERthe software world has stabilized over the last 50 years until there's like an intermediate

15:01SPEAKERformat that all printers understand.

15:03SPEAKERAnd you like, you don't have to have like your computer doesn't have to speak the printer's

15:07SPEAKERlanguage and know how to send it fonts and all that stuff.

15:10SPEAKERBut like with the slicers, the slicer has to understand the capabilities of your printer.

15:14SPEAKERSo your slicer has to know about your printer, right?

15:17SPEAKERJust some variables.

15:18SPEAKERI mean, the open source slicers, you know, they have to know, you know, the volume of

15:24SPEAKERthe printer.

15:25SPEAKERThey have to know the hot end that you're using, right?

15:29SPEAKERThe diameter.

15:30SPEAKERAnd like the one, you know, there's, there's a speed variable, right?

15:33SPEAKERWhereas the way these printers design, whether it's a bed slinger printer and a bed slinger,

15:38SPEAKERit just means that the, the actual bed of the, the print bill build plate is moved across

15:44SPEAKERthe Y axis and your X and your Z axis are moved up a gantry or a an arm.

15:52SPEAKERAnd that was a very popular style design of printer.

15:57SPEAKERAll of that is just, you know, these are just numbers and through a configuration setting

16:00SPEAKERthat the slicer gets in and you know, the more the, the, the, the higher end common

16:06SPEAKERprinters are on now in this, what's called a core X, Y design.

16:11SPEAKERSo when you think of like the enclosed bamboo boxes or what even in crowdy and what even

16:17SPEAKERproves us put out now these are the fastest printers and that's because the bed moves

16:22SPEAKERup and down.

16:23SPEAKERYou know, they, there's like one one screw drive that moves and you know, one motor,

16:28SPEAKERthe separate motor that helps the bed move and usually lowers or starts at the top and

16:32SPEAKERlowers to the bottom.

16:33SPEAKERAnd then the X, Y axes are controlled by two motors, but they're controlled by belt drives

16:39SPEAKERthat work simultaneously.

16:41SPEAKERSo the math is done.

16:42SPEAKERSo it's not just one motor that moves the X axis, the X and Y.

16:45SPEAKERThey move diagonally really fast and using this belt drive, these belt drives, the X,

16:52SPEAKERY drawing of that, that, you know, the, that each layer, each cross section can happen

16:58SPEAKERreally fast.

16:59SPEAKERAnd then they also built in compensation for the motors.

17:01SPEAKERAnd a lot of this has to do with algorithms developed in like the drone world.

17:06SPEAKERYou know, the, like the DJI engineers that now were founded bamboo, but also in the open

17:13SPEAKERsource 3d printing community, there was a algorithm called Kipler or a software, a firmware

17:18SPEAKERsuite called Kipler, and they also introduced these kind of resonance compensating algorithms.

17:24SPEAKERAnd so these, the hot end and the motors can move extremely fast, but you don't get any

17:30SPEAKERof the negative effects of resonance.

17:32SPEAKERThe wobble and jitter that you used to get if you made your, it's funny, the belt, the

17:37SPEAKERbelt drive stuff, it makes me want like, it's, it's essentially, it's essentially like you're

17:41SPEAKERcontrolling it with the belt drive units.

17:43SPEAKERIt's essentially like you're doing an edge sketch drawing, right?

17:46SPEAKERIt's really, really fast, really fast et cetera.

17:49SPEAKERAnd when we first saw them operate, it was unbelievable.

17:53SPEAKERAnd you know, you look at the stats of the printers, you look at the, the, the speed

17:56SPEAKERat which there's a max speed that the, uh, the hot end, the extruder can move at.

18:01SPEAKERThere's a max speed, there's max acceleration that they move out.

18:05SPEAKERAnd these are all in like the hundreds of millimeters per second.

18:08SPEAKERBut then also there's the variable that matters the most is the throughput kind of the, um,

18:14SPEAKERhow much plastic it can poop out.

18:16SPEAKERYes.

18:17SPEAKERYeah.

18:18SPEAKERYeah.

18:19SPEAKERUm, and the, the, the actual literal, like, yeah, which is a derivative of also the movement,

18:24SPEAKERright?

18:25SPEAKERAnd also the layer height, but the, that the, uh, the heat of the nozzle, how hot it can

18:31SPEAKERget, how reliable that extruder is, the quality of the material, um, all of that then funnels

18:37SPEAKERinto this number of your, your throughput.

18:40SPEAKERAnd then, you know, layers like the complexity of a print really affects, it's correlated

18:47SPEAKERto how long a print takes a cube is in a small cube is going to be much less time than something

18:52SPEAKERthat has like a, let's say a large, um, surface area or each cross section is having a big

18:57SPEAKERoutline, right?

18:58SPEAKERCause then you have to actually do a lot of physical movement, um, to draw each of those.

19:03SPEAKERUh, but it's all so reliable now.

19:05SPEAKERAnd then the things that we used up to worry about, like adhesion, that's completely problems

19:10SPEAKERsolve problem.

19:11SPEAKERBut PLA is a standard.

19:12SPEAKERNow these, uh, these PI build plates, textured bill plates, you know, the level of self-leveling

19:18SPEAKERis all done really.

19:19SPEAKERUm, uh, it's all standard and the heated plates plus the PI texture means that, you know,

19:26SPEAKERit's warm.

19:27SPEAKERIt sticks.

19:28SPEAKERYeah.

19:29SPEAKERYou maybe have to do a little bit of a brim, but then once you finish printing, they just

19:31SPEAKERpop off and there's zero scraping.

19:34SPEAKERThat sounds, yeah.

19:35SPEAKERZero scraping.

19:36SPEAKERI remember having to get the acetone out and smear the ABS all around.

19:40SPEAKEROh my God.

19:41SPEAKERIt was a nightmare.

19:42SPEAKERYeah.

19:43SPEAKERUm, so, okay.

19:44SPEAKERSo are the slicers, cause the slicing is where the hard for, for me to success and failure

19:50SPEAKERthe print, the old days was a lot in how you sliced it.

19:53SPEAKERAnd the slices were kind of dumb weirdly.

19:57SPEAKERLike they didn't, they wouldn't, they wouldn't look at a print and be like, Oh, you need

20:00SPEAKERsupport material here.

20:01SPEAKERCause this is going to sag.

20:02SPEAKERThey would just let you print it and then it would sag and then you ended up with spaghetti

20:05SPEAKERnightmare at the end of 10 hours.

20:07SPEAKERLike, are they, had they gone beyond that point or it's still some skill and nuance

20:10SPEAKERin using the slicers?

20:13SPEAKERThis they are turnkey in that you can literally press a button and 95% of the time old work

20:19SPEAKERand you can say generate supports and even the style of support.

20:23SPEAKERSo you can tune everything, right?

20:24SPEAKERYou can turn layer height.

20:26SPEAKERYou can tune even like the, the, the width of the line with, you know, if you're using

20:31SPEAKERa point for a nozzle, you have actually have a nice range of how wide your line is, how

20:35SPEAKERmuch it smushes it in.

20:37SPEAKERSo exactly.

20:38SPEAKERRight.

20:39SPEAKERRight.

20:40SPEAKERYup.

20:41SPEAKERYup.

20:42SPEAKERAnd that, you know, how, how fast the nozzle moves, how thick it lays down that line.

20:44SPEAKERYou can tune the infill, right?

20:46SPEAKERLike we used to have to do it like, you know, thick the shell of this print is and the style

20:51SPEAKERof infill, right?

20:52SPEAKERWhether it's a gyroid design or a zigzag and exactly the eat, all these offer different

20:57SPEAKERproperties and how much filament uses and how fast they can move.

21:01SPEAKERBut supports even in supports, right?

21:05SPEAKERThere are these organic tree supports now.

21:07SPEAKERSo it's not just like these pillars that come up from the ground or from, from the build

21:11SPEAKERplate and attached to the overhangs, you know, they're more organic and so the supports don't

21:16SPEAKERfail themselves, but you can even tune things like how much the support is touching the

21:21SPEAKERmaterial.

21:22SPEAKEROh, right.

21:23SPEAKERLike what that content, what that contact point is, what the interface layer is.

21:29SPEAKERAnd the, the thing that you probably want to worry about most is just the orientation

21:32SPEAKERof your print.

21:33SPEAKERAnd so there's, you know, the, the thing that printer won't understand is gravity, right?

21:37SPEAKERThe weight of an object understand, you know, shape wise, geometrically, there is an overhang

21:43SPEAKERor you'll, you'll know that like for this part of the print, it's at this angle and

21:47SPEAKERthere's nothing underneath it.

21:49SPEAKERYou should probably automatically generate a support underneath it.

21:52SPEAKERBut what it can't determine is that, Oh, at this point, the cantilever is so far out that

21:58SPEAKERthe weight of the object will maybe apply forces to the base of the print and want to

22:03SPEAKERlift it off the bed or something.

22:05SPEAKERSo they won't do the thing like, cause the thing, the thing that people who are good

22:08SPEAKERat this do is they'll look at the model and be like, Oh, I need to rotate this model like

22:11SPEAKER30 degrees to the left.

22:13SPEAKERSo it's kind of, so the whole thing gets support automatically and, and know that, and they're

22:18SPEAKERnot, the software doesn't, doesn't give you that recommendation yet.

22:22SPEAKERYeah.

22:23SPEAKERYeah.

22:24SPEAKERI mean, it'll, it'll, it'll do some math and the thing better.

22:26SPEAKERBut also it won't care about your finishes, right?

22:29SPEAKERYou might want to angle your print because you want your layer lines to be oriented in

22:33SPEAKERa certain direction.

22:34SPEAKERLike if you're printing a portrait, you typically want to tilt the face up.

22:37SPEAKERSo the tip of the nose gets like, you know, the last drawn, you know, you don't want to

22:41SPEAKERhave your overhang being underneath the nose.

22:42SPEAKERYou know, there are certain just orientations for certain types of objects that just make

22:46SPEAKERmore sense.

22:47SPEAKERRight.

22:48SPEAKERAnd so, yeah, I think the software has gotten, you know, long story short software has gotten

22:53SPEAKERreally good.

22:54SPEAKERAnd not a lot of that's open source.

22:55SPEAKERYeah.

22:56SPEAKERYeah.

22:57SPEAKERWhat are the, what are the kind of big, cause like if you buy a commercial printer, you

23:02SPEAKERget the software they come with, but then also a lot of the open software work with

23:05SPEAKERthat as well.

23:06SPEAKERRight.

23:07SPEAKERFor the most part.

23:08SPEAKERYeah.

23:09SPEAKERFor the most part.

23:10SPEAKEROkay.

23:11SPEAKEROrca is the most popular one.

23:12SPEAKERKira, which also maker makes a still very popular, you know, proves a slicer works with,

23:17SPEAKERwith everything.

23:18SPEAKEROrca stuff is, you know, kind of derivative of the, of what proves that had developed

23:21SPEAKERand put out in the open source community.

23:24SPEAKERYeah.

23:25SPEAKERAnd I primarily use, you know, the bamboo lab stuff cause they have all their profiles.

23:31SPEAKERBut the Orca stuff is also really good.

23:32SPEAKEROkay.

23:33SPEAKEROkay.

23:34SPEAKERSo let's talk about printers then.

23:35SPEAKERSo we talked a lot about FDM.

23:37SPEAKERThe basic idea I think we've gotten, but the stuff that's changed lately is multi multi

23:42SPEAKERfilament printers seem to be the rage right now.

23:46SPEAKERThat's this year.

23:47SPEAKERThis year, the big thing is multi material, multi filament.

23:52SPEAKERAnd it happens in a bunch of different ways, right?

23:54SPEAKERSo what bamboo lab and then proves that done this for a while.

23:58SPEAKERBut what bamboo lab really popularized is the idea that with one nozzle, with one extruder,

24:03SPEAKERyou can automatically feed in different colors or different types of filament by having a

24:10SPEAKERbox that stores four different roles in them.

24:13SPEAKERYeah, this is there.

24:14SPEAKERWe call this the AMS system, the automatic material switching system.

24:18SPEAKERAnd so in that box, the printer knows it is connected to it via data cable.

24:23SPEAKERThere's one bounding tube that connects to the printer.

24:26SPEAKERIt retracts and you can like dispense whichever of these four filaments you want.

24:32SPEAKERAnd for me, it's like really convenient just to not have to remove a wall and, you know,

24:36SPEAKERsnip off the printer and feed something in.

24:38SPEAKERSo these are my four favorite colors.

24:40SPEAKERAnd you know, I'm in the slicer and say, today I'm going to print in gray or it's my black.

24:44SPEAKEROr if you want to say all of them are my generic white rolls.

24:47SPEAKERAnd if I finish about the kilogram will automatically feed in another spool.

24:52SPEAKERAnd so you don't have to worry about like running out of filament or wasting having

24:55SPEAKERthese like, you know, tens of grams of film that left in a spool.

24:59SPEAKERBut for multicolor, the slicer basically can work in a couple different ways.

25:03SPEAKERIn the old days, you think of a multicolor print is basically like a puzzle piece of

25:08SPEAKERdifferent colors.

25:09SPEAKEREach color is a like a different model and the model is basically split up into however

25:16SPEAKERmany different colors you'd want.

25:18SPEAKERNow you can actually go into the slicer software and just kind of literally paint, you know,

25:22SPEAKERwhat paint bucket.

25:23SPEAKERYep.

25:24SPEAKERReally just say for these facets or this surface and this amount of tolerance, you know, Photoshop

25:29SPEAKERstyle, just paint that white and paint that black and it will automatically parse that

25:34SPEAKERout.

25:35SPEAKERThat is wild.

25:36SPEAKERLike do the, like if you're doing something, will it, and can you specify which color you

25:41SPEAKERdo for fill and stuff like that too?

25:42SPEAKEROh yeah.

25:43SPEAKEROh yeah.

25:44SPEAKERYeah.

25:45SPEAKERWith supports can be a different material.

25:46SPEAKERSo going back to even supports, one of the great things that we do is there used to be

25:50SPEAKERlike, you know, water soluble supports was a really popular thing.

25:53SPEAKERYeah.

25:54SPEAKERNow what was actually really important is the interface layer is the part that you want

26:00SPEAKERto have a different material.

26:01SPEAKERSo the interface layer between the support and the, Oh, between the support and the model

26:06SPEAKERexactly.

26:07SPEAKERRight.

26:08SPEAKERSo if I'm printing a PLA model, I'm probably printing, most of it's going to be PLA, including

26:13SPEAKERthe supports, but the part where the support touches the model, which just needs to be

26:18SPEAKERlike a physical piece of contact, right.

26:20SPEAKERIt doesn't need to actually, adhesion is not super important, but I would select that as

26:25SPEAKERPTG and PTG and PLA do not, they, they, they have different like melting points and they

26:31SPEAKERdon't, you know, when they cool down, they actually separate.

26:34SPEAKERThen if I'm printing a PLA model, my interface layer is PTG, if I'm printing a PTG model,

26:40SPEAKERmy interface layer is PLA.

26:41SPEAKERAnd then when the print's done, they don't shear apart.

26:44SPEAKERThey just literally separate.

26:46SPEAKEROh, wow.

26:47SPEAKERYeah.

26:48SPEAKERSo it just provides while it's warm and then release.

26:50SPEAKERWow.

26:51SPEAKERThat's wild.

26:52SPEAKEROkay.

26:53SPEAKERSo multiple zero, right.

26:54SPEAKERRight.

26:55SPEAKERSo let's say color model.

26:56SPEAKERYep.

26:57SPEAKERYeah.

26:58SPEAKERI, you know, the slicer will do the math and do the calculation and even like a factor

27:01SPEAKERin the fact that if you're using a single nozzle printer with like, you know, four or

27:06SPEAKERmore filaments being funneled through a single tube, it'll need to purge between the colors.

27:14SPEAKERSo your cross sections look a little more complicated.

27:16SPEAKERSo let's say you're printing a model and it's a character and at the feet of the model,

27:20SPEAKERthe base of the model, the feet, you have like two colors, right?

27:23SPEAKERYou have like the feet and the toes and the feet, right?

27:26SPEAKERBlack and like a Pikachu or I don't want to see the toes, man.

27:29SPEAKERYou have the detail there.

27:32SPEAKERSo like your cross section might have two or more colors.

27:35SPEAKERAnd so it will draw the outline and draw the shape of one of the colors.

27:40SPEAKERAnd then when it reaches the end of that point, the printer will retract automatically cut

27:45SPEAKERand retract that spool.

27:48SPEAKERAnd then it will feed in the next, where does it cut at the, at the end of the hot end?

27:53SPEAKERNo, that's actually the hot end at the entry.

27:56SPEAKERYes.

27:57SPEAKERSo not at the nozzle, not the exit point cuts at the.

27:59SPEAKERAnd so there's a little bit of a space, right?

28:01SPEAKERThere's still over, you know, a couple of centimeters of that.

28:06SPEAKERIt's the mystery dumb dumb flavor.

28:07SPEAKERIt's where the, where the filaments mix.

28:09SPEAKERRight.

28:10SPEAKERAnd so, you know, in these types of printers, there needs to be a purge, right?

28:14SPEAKERSo it will purge out into its little poop chute.

28:16SPEAKERIt will push out a little bit of it'll do the, it'll know, it'll do the math and know

28:22SPEAKERlike I need to purge out a couple of grams or, you know, a couple of centimeters of the

28:27SPEAKERold filament engines of filament that it pushes in is what it knows probably right.

28:30SPEAKERYeah.

28:31SPEAKERWho comes out and then it'll create a, what's called a prime tower.

28:34SPEAKERSo it'll start wiping.

28:35SPEAKERI'll heat up the nozzle and I'll kind of like wipe and get the flow working at the, and

28:41SPEAKERthen and then resume printing.

28:42SPEAKERAnd so that switch time is actually a huge part of the time.

28:48SPEAKERIt seems substantial.

28:49SPEAKERYeah.

28:50SPEAKERIt needs to poop.

28:51SPEAKERIt needs a prime and then it needs to draw the second color.

28:56SPEAKERAnd so if you have a really complex model where the cross section is like four colors,

29:01SPEAKERjust to draw that one layer can take, you know, four or five times at least the amount

29:06SPEAKERof time to print as if it was just a single color.

29:10SPEAKERHow does doing the prime tower not crash into the rest of the, like if you're, if you're

29:14SPEAKERbringing it back, it's not, it's not on the bed.

29:18SPEAKEROkay.

29:19SPEAKEROkay.

29:20SPEAKERAnd then some people, you know, you can even tweak the settings to say like, do the prime

29:22SPEAKERas the infill or do the prime as the support.

29:27SPEAKERBut you know, your, your success may vary and you, sometimes you get the, if you don't

29:32SPEAKERdo the prime, you get the boogers that stick out at the edge of the print.

29:34SPEAKERYeah.

29:35SPEAKERNobody wants that.

29:36SPEAKERYeah.

29:37SPEAKERSo that's really time consuming and, but that's a really reliable and kind of really cheap

29:41SPEAKERway to do multicolor.

29:43SPEAKEROkay.

29:44SPEAKERThe more advanced ways, which come out last year and this year are to have more, more

29:50SPEAKERhot ends, right to literally have a tool extrusion printer or more.

29:55SPEAKERAnd so bamboo, you know, had a, they put out the H2D last year and this has on the gantry

30:01SPEAKERor on the, on the core XY system has two, two extruders.

30:06SPEAKERAnd so it can feed in from two different sources.

30:10SPEAKERSo you can have like two of their, their AMS systems feed in, or you can have a big role

30:15SPEAKERin the outside.

30:16SPEAKERAnd what I found that was that two colors actually is pretty, or having two nozzles

30:20SPEAKERis pretty effective.

30:21SPEAKERIt doesn't limit you to two colors, but you can think of like one as your base color.

30:26SPEAKERLike again, going back to the Pikachu example, vast majority of it's going to be yellow,

30:30SPEAKERright?

30:31SPEAKERYeah.

30:32SPEAKERAnd just kind of accents.

30:33SPEAKERYeah.

30:34SPEAKERYeah.

30:35SPEAKERAnd so when you think of a cross section, most of the time, the cross section is going

30:39SPEAKERto be the base color and going to be maybe one of the accents and maybe one or two of

30:44SPEAKERthe accent colors.

30:45SPEAKERAnd so when you have two nozzles and you have one that's dedicated to the base color, that

30:50SPEAKERbase color one never needs to poop, never needs to purr or still needs to prime technically,

30:55SPEAKERbut never needs to poop.

30:56SPEAKERAnd so you're not having to waste as much filament and it cuts down the time significantly.

31:03SPEAKERSo is this smart enough to do like, if it knows it has two color changes coming up,

31:07SPEAKERsay you want to change to PETG in a different accent color, will it do both of those at

31:11SPEAKERthe same time?

31:12SPEAKEROr can it?

31:16SPEAKERIt can't feed two at the same time.

31:18SPEAKERAnd that's really, I don't think that's as important.

31:20SPEAKERI mean, the time consuming process probably is the pooping and the retracting and the

31:25SPEAKERfeeding.

31:26SPEAKEROkay.

31:27SPEAKERCause it needs to spool back up and retract the spool and there are some efficiencies

31:33SPEAKERthat they could be implementing to feed into both hot ends more efficiently.

31:38SPEAKEROkay.

31:39SPEAKERIt still sounds like a pretty remarkable improvement over the single head machines of your, and

31:45SPEAKERthen there are two, like two, two further improvements.

31:47SPEAKERSo there is a H2C printer that was late last year.

31:52SPEAKERAnd this one, instead of having two nozzles has one dedicated nozzle on one end.

31:57SPEAKERAnd the second one could swap between seven, six different nozzles, the six tool head or

32:05SPEAKERsix extruder exchanger that has this mechanized system to actually swap out.

32:11SPEAKERAnd so that little bit of, you know, three centimeters of extra filament, it just stays

32:18SPEAKERwith the hot end and the hot end gets back in and locked into the extruder when when

32:26SPEAKERthe new filament comes in.

32:27SPEAKERSo do you buy a hot end for every new kind of filament you get basically?

32:32SPEAKERYou can still purge.

32:34SPEAKERSo you do want to have like, you know, you want to fill the rack up with those six hot

32:37SPEAKERends.

32:38SPEAKERYeah.

32:39SPEAKERYeah.

32:40SPEAKERYeah.

32:41SPEAKERHow much like hot ends or there's not a whole lot of complexity to hot ends.

32:42SPEAKERIt's just a metal tube with the heating element, right?

32:44SPEAKERAnd a thermistor, or is it more complicated than that now?

32:48SPEAKERThe ones in the changer that I talked about in H2C have electronics in there and they have

32:53SPEAKERinduction heating.

32:54SPEAKERSo, you know, they move some of that complexity to the hot end, but in general, the hot ends

32:58SPEAKERare, and most of the printers are really easily swappable, like really just like pull a latch,

33:04SPEAKERmagnet pulls out and you can, you can buy different diameters.

33:07SPEAKERSo standard is 0.4, but you can go 0.2, 0.4, 0.6, 0.8, fat nozzle hot ends are really great

33:13SPEAKERfor printing really fast because that volumetric throughput is really high.

33:16SPEAKERAnd so you set your layer heights, if you're printing at 0.8, you know, your layer heights

33:21SPEAKERgoing to be, you know, really like 200 microns or something, or like four or 500 microns,

33:27SPEAKERyou could print like a big vase, like in like, you know, 20 or 30 minutes.

33:32SPEAKERYeah, exactly.

33:33SPEAKERLike it'll just print really, really fast.

33:36SPEAKERAnd then there are like fast throughput nozzles as well.

33:39SPEAKERThey're just made with, you know, the better materials and they can heat faster and that

33:43SPEAKERvolumetric throughput is just really, really high.

33:46SPEAKERHow's this like, how accurate is the scaling?

33:50SPEAKERAnd like, if you print something that you feed a model and that you think is going to

33:52SPEAKERbe, you know, 10 centimeters across, is it going to end up 10 centimeters across exactly

33:58SPEAKERor is it going to end up 10.25 or 9.75 or like, what's the tolerances like these days?

34:06SPEAKERReally really close.

34:07SPEAKERAnd a lot of it's the material too, you know, there's going to be a little bit of shrinking,

34:10SPEAKERmaybe a little bit of warping, how strong you set up your model.

34:15SPEAKERSo, you know, more shell layers instead of infill.

34:21SPEAKERBut warping isn't really that much of a problem and dimensionally it's really accurate.

34:27SPEAKERYeah.

34:28SPEAKEROkay.

34:29SPEAKERYeah.

34:30SPEAKERI mean, I got to say it's one of the things that I really loved about laser cutting when

34:31SPEAKERI first started using the laser cutter is that it's like absolutely precise every time

34:35SPEAKERunless you screw something up, which was not the case with the 3D printers at the time.

34:39SPEAKERSo that's cool.

34:41SPEAKERWhat about, okay, so big giant print areas, like do you lose, do you lose speed and stuff

34:48SPEAKERwhen you go with a huge printer or is it just that you can print more and it takes, you

34:51SPEAKERknow, obviously printing a bigger thing takes longer.

34:54SPEAKERYeah.

34:55SPEAKERAnd the printer is now all like the standard size is still probably 256 by 256 by 256 millimeters.

35:03SPEAKERSo it's like 10 inches, 10 inches cube.

35:07SPEAKERThat's a great desktop size.

35:10SPEAKERThe larger ones go over 300, you know, 325 millimeters.

35:15SPEAKERSo you're talking about over a foot.

35:17SPEAKERAnd the way I think about it is those are great if you want to make stuff on Etsy to

35:22SPEAKERsell and you can like have a big build plate with a ton of, you know, you can pack that.

35:27SPEAKEREspecially if you're, if you're doing these, the multi-material printing or the multicolor

35:31SPEAKERprinting, your efficiencies are really increased if you're printing multiple objects.

35:36SPEAKERThat's the other thing I didn't mention because you know, writing 10 things as opposed to

35:40SPEAKERone thing, it still has to do the filament swap, but you're changing the filament swap

35:44SPEAKERnow by printing 10 things as opposed to printing one thing at a time.

35:48SPEAKERYeah.

35:49SPEAKERIt's a 10 X improvement.

35:50SPEAKERRight?

35:51SPEAKERYeah.

35:52SPEAKERYeah.

35:53SPEAKERSo mass production, you want, you might not need the Z height because most of these things

35:56SPEAKERbeing mass producer, small squatty, you know, little key chain things, whatever people sell

36:01SPEAKERon Etsy or at farmer's markets or like I buy things that let me mount specific devices

36:05SPEAKERunder my desk that are 3d printed.

36:07SPEAKERRight.

36:08SPEAKERLike that, like that kind of stuff is really convenient and exactly what it's for.

36:13SPEAKERBut all, you know, people printing stuff to, for, you know, costumes and props, I usually

36:18SPEAKERdescribe it in terms of you know, are these hand prop size things?

36:23SPEAKERAre these are these wearable pieces, you know, the helmets, you know, when you're moving

36:29SPEAKERinto that 300 millimeter plus size, you can get into like, you know, helmets that kids

36:34SPEAKERcan wear, but you probably need to print two plates for a helmet for an adult to wear.

36:39SPEAKERAre they, if you buy a big giant printer, are you sacrificing low end, like small scale

36:46SPEAKERresolution?

36:47SPEAKERNo, no.

36:48SPEAKEROkay.

36:49SPEAKERThe accuracy is still there.

36:50SPEAKERIt consumes a lot more power though.

36:51SPEAKERRight?

36:52SPEAKERCause you have a bigger plate, a bigger volume theoretically to heat if you're, if you need

36:56SPEAKERa heated build volume.

36:57SPEAKERAnd so the power consumption just goes through the roof.

37:00SPEAKERI was gonna say, let's talk, can we talk about enclosed printers?

37:02SPEAKERCause I feel like that's the, that's the other thing that's, that's, that was a relatively

37:06SPEAKERnovel concept when I last dipped out and, and now everybody's like, it seems like enclosed

37:14SPEAKERis the way to go.

37:15SPEAKERYeah.

37:16SPEAKERAnd the, you know, there's a really, there was a popular era where these bedslingers

37:20SPEAKERthat, you know, cruelty made we're all open, right?

37:23SPEAKERAnd PLA is non-toxic and you don't want particulates, right?

37:26SPEAKERYou know that you don't want to be like huffing this stuff in.

37:29SPEAKERYeah.

37:30SPEAKERIt seems like those things are non-toxic asterisk in the, Hey, we haven't been doing this for

37:35SPEAKERlong enough to know what the actual long-term repercussions are.

37:38SPEAKERRight.

37:39SPEAKERYeah.

37:40SPEAKERSo most of the ones that are Quarx Y are enclosed.

37:42SPEAKERThey have doors.

37:43SPEAKERThe question is whether they have heated volumes because they can all heat the volume using

37:53SPEAKERthe bed plate.

37:54SPEAKERSo they'll just heat the bed up and then, you know, use check the thermistor to make

37:57SPEAKERsure the volume is heated if you need to print, you know, ABS.

38:02SPEAKERBut the higher end printers will have dedicated blowers that blow hot air in and control the

38:07SPEAKERtemperature that way.

38:08SPEAKERIs that, is that an ABS thing still like the, just because of the warping between the, the,

38:13SPEAKERlike the liquid phase and the solid phase.

38:16SPEAKERYeah.

38:17SPEAKEROkay.

38:18SPEAKERAnd then engineering or engineering filaments.

38:19SPEAKERAnd most of the stuff I'm putting though, the PTG PLA stuff, you don't need the, the

38:25SPEAKERheated volume.

38:26SPEAKERAnd in fact, they, you don't want to have too hot of volume because then that will warp.

38:30SPEAKERAnd so they actually vent out of the air.

38:32SPEAKERThey, you know, the bamboo printers have even like a, a little exhaust, an event that lifts

38:36SPEAKERup for PLA or they asked you to keep the door open because you, you want it to be cooled

38:41SPEAKERfaster.

38:42SPEAKERThey have a cool air blower that blows across the plane of the, the hot end so that the

38:47SPEAKERmoment it comes out of the extruder, it's solid.

38:50SPEAKERDo they, do they filter their, do they filter exhaust in those?

38:56SPEAKERNot really.

38:57SPEAKERThere is an exhaust and you can buy aftermarket filtration systems, which are recommended

39:02SPEAKERlike that, literally attached to the most popular printers and, and little fans there.

39:07SPEAKERAnd people vent out, you know, out their windows if they're doing more toxic stuff.

39:11SPEAKERBut there's not a ton of good filtration that's built in.

39:15SPEAKERI wondered, cause like I remember in the old days when we used to sit in the office in

39:19SPEAKERthe small room with the, with the ABS printer going all the time.

39:22SPEAKERAnd then I think we both ended up with headaches at the end of the day, pretty much pretty

39:26SPEAKERconsistently when we were doing that.

39:27SPEAKERNot too.

39:28SPEAKERRight.

39:29SPEAKERYeah.

39:30SPEAKERLike, like it was a series of bad ideas just to be clear.

39:33SPEAKERBut but yeah, I wondered if they were actually filtering cause cause like we've seen that

39:37SPEAKERin the electronic space where people are more, I mean, some people have always been very

39:41SPEAKERserious about solder fumes and breathing flux, flux fumes and stuff like that.

39:47SPEAKERBut yeah.

39:49SPEAKERI think that's like, what's the kind of, what's the material situation with the, with the

39:54SPEAKERFTF it's mostly PLA, PTG stuff, PT, I can't remember what plastic PTG is.

40:00SPEAKERIt's like water bottle plastic.

40:01SPEAKEROkay.

40:02SPEAKERYeah.

40:03SPEAKERPLA is a corn starch based, right?

40:04SPEAKERYes.

40:05SPEAKERAnd so PTG will last a little better, a little more resilient.

40:08SPEAKERI wouldn't use it for any, like you're not going to install your dryer vent using any

40:14SPEAKERof this stuff.

40:15SPEAKERRight.

40:16SPEAKERYeah.

40:17SPEAKERIt's still going to melt at those temperatures.

40:18SPEAKERBut PT, I mean, there's so many color options, a lot of great suppliers of filament.

40:23SPEAKERIt's getting harder and harder cause there's so many people with 3d printers and like even

40:26SPEAKERbuying PTG, it just sells out so quickly.

40:28SPEAKERSo people stock up a lot, you know, a good rule of thumb is you can buy a roll, a kilogram

40:36SPEAKERfor like 18, 16 to $18.

40:39SPEAKERI think it's a good price for a roll of filament.

40:43SPEAKERBut I sometimes buy like for matter hackers, you know, five kilogram roll, like a giant

40:47SPEAKERroll and then you can print out a little spool feeder cause I just know I needed that much

40:51SPEAKERwhite, black and gray.

40:52SPEAKERRight.

40:53SPEAKERAnd, and so how, how much does a kilogram, like if you're printing vases, right.

40:58SPEAKERIf you're putting like potted potted plant holders for small potted plants that are like,

41:03SPEAKERI don't know, two liter, two liter pots, like how much plastic

41:07SPEAKERA big vase probably, I mean, again, it depends on the infill, but I'd say more like that's

41:12SPEAKERlike 200 grams, 250 grams.

41:14SPEAKEROh, so like five of them for a roll pretty much.

41:17SPEAKERYeah.

41:18SPEAKERThat seems pretty good.

41:19SPEAKERYeah.

41:20SPEAKERIt seems doable.

41:21SPEAKERYeah.

41:22SPEAKERSo those are going to be like 50 grams, 40 grams.

41:25SPEAKERYeah.

41:26SPEAKERAnd do you do a lot of stuff that's full infill these days or is it mostly, mostly hollow?

41:30SPEAKERIt's mostly hollow.

41:31SPEAKERI'd say like I go like 15% infill gyroid.

41:34SPEAKERAnd my rule of thumb is I'd rather increase the outline, the shell thickness for rigidity

41:41SPEAKERthan infill.

41:42SPEAKERGot it.

41:43SPEAKERYou can do full infill if you want weight to have something to feel really weighty,

41:46SPEAKERbut you know, you can also put embed magnets in there or pause it and fill it with the

41:52SPEAKERbottom or something.

41:53SPEAKERYeah.

41:54SPEAKERPeople do really awesome things.

41:55SPEAKERLike there's like, we haven't touched on, you know, the, the, the the type of like art

42:00SPEAKERthat people are making with three prints cause they use the texture of the build plate as

42:05SPEAKERlike the surface of the art face down multicolor and the magnets, they sometimes, you know,

42:12SPEAKERstop the print and have a stop in the G code per certain parts of the layer.

42:16SPEAKERSo they can literally drop magnets into the recesses and then print over the magnets.

42:20SPEAKERAnd so they have embedded materials in the print.

42:23SPEAKERLike these are all pretty common things that people have great instructions and guides

42:26SPEAKERfor doing.

42:27SPEAKERYeah.

42:28SPEAKERI follow.

42:29SPEAKERThere's a guy I follow who does a lot of that and he takes advantage of, I don't, they're

42:34SPEAKERlike common mechanical interfaces, I guess is the way to describe it.

42:37SPEAKERSo he buys a bunch of like female quarter inch, like the, the, the screw Mount that

42:42SPEAKERyou use on every photo on every camera tripod ever.

42:46SPEAKERSo then he has a bazillion things you can amount to tripods or to the greater tripod

42:50SPEAKERindustrial complex of which there's a bazillion types of mounts and interfaces and stuff like

42:55SPEAKERthat.

42:56SPEAKERThere's also a lot of like, people have come up with a lot of interesting mechanical mounts.

42:59SPEAKERIt seems like where they like, where you have like a, you know, two pieces that one slides

43:04SPEAKERinto the other and then it snaps into place, just like something you'd get with injection

43:07SPEAKERmolded plastic, which is, which is pretty cool.

43:09SPEAKERYeah.

43:10SPEAKERThere's a whole print in place.

43:11SPEAKERThere's also a design philosophy where because of the way it prints these layers, you can

43:16SPEAKERdo linkages.

43:17SPEAKERLike you just get that benefit of having things that come out, they're linked together.

43:22SPEAKERAnd so these really great 3d designers can like design characters, the arms move, or

43:28SPEAKERthat once you print it, you can lift off the bed and snap a certain thing into place and

43:32SPEAKERyou get this cool mechanical complexity that'd be really hard to do otherwise.

43:37SPEAKERIt's really cool.

43:39SPEAKERLet's see a post-print treatment stuff.

43:41SPEAKERDo you do anything to these printed prints these days?

43:43SPEAKERYou just basically take it out at the printer.

43:45SPEAKERYou're ready to go.

43:46SPEAKERThat's it.

43:47SPEAKERI mean, the quality is so good that, you know, and it's not like it's, it's not a look that

43:52SPEAKERpeople shy away from anymore.

43:53SPEAKERIt used to be that like people are like, Oh no, that's like, that's 3d printed that must

43:57SPEAKERlook cheap.

43:58SPEAKERBut like, you can like, if you look around the world, there's, there are 3d printed parts

44:02SPEAKEReverywhere.

44:03SPEAKERYou know, people use them on buses, people repair houses with them.

44:07SPEAKERLike they sell 3d printed trinkets in stores.

44:09SPEAKERLike, it's just an accepted style and, and you're printing, like people are printing

44:13SPEAKERinto all sorts of like different, like texture materials you can add, like in the slicer,

44:19SPEAKERyou know, settings allow for fuzzy skin, the things have like a, they just feel different.

44:23SPEAKERSo it's not just that kind of layer line look.

44:26SPEAKERAnd even in the industrial world, you know, there are filaments that have like carbon

44:29SPEAKERfiber perfectly inlaid in the, in the film and Mark Forge sells some really like in line.

44:36SPEAKERExactly.

44:37SPEAKERWow.

44:38SPEAKERAnd so you get really strong rigidity with that and it's like, they won't separate and

44:42SPEAKERthey're just as good as, you know, cast parts.

44:45SPEAKERIt's funny.

44:46SPEAKERI, there was a guy at one of the street festivals here in town last year that had 3d printed

44:51SPEAKERstuff that I think he was blow torching to get soft again and then rolling in sand.

44:55SPEAKEROh wow.

44:56SPEAKERAnd it was, it was wild.

44:58SPEAKERIt looked like it almost looked like, like when I was a kid, some of my more hippy dippy

45:03SPEAKERaunts and uncles used to make like sand cast candles where they would go out and dig a

45:07SPEAKERhole in the sand and then pour wax in and put a wick in there and you'd dig it out and

45:11SPEAKERyou get a candle looked like a weird dragon egg or something.

45:15SPEAKERAnd it was very reminiscent of that stuff.

45:17SPEAKERIt was neat.

45:18SPEAKEROkay.

45:19SPEAKERSo let's, if you're recommending printers in this, like a few, like sub 250, 500 to

45:25SPEAKERa thousand and then maybe like if you want to buy something fancy.

45:28SPEAKEROh my goodness.

45:29SPEAKEROkay.

45:30SPEAKERI know this is incredibly reductive.

45:31SPEAKERI'm sorry.

45:32SPEAKERYes.

45:33SPEAKEROkay.

45:34SPEAKERSo if you have a, let's say middle schooler, once again, the three printing, I have a middle

45:39SPEAKERschooler who wants to get a 3d print, what a weird coincidence.

45:42SPEAKERYes.

45:43SPEAKERAnd let's say you don't want to spend more than $250 for about $250.

45:47SPEAKERYou can get the bamboo lab, a one mini and they keep on sale.

45:51SPEAKERAnd I would say just get the standard printer.

45:57SPEAKERYou don't need the multi-material multi feeder that saves you like, you know, a hundred bucks.

46:04SPEAKERAnd you can even buy that as an aftermarket upgrade.

46:06SPEAKERAnd that will get you started just getting the reps of understanding how to slice or

46:10SPEAKERworks.

46:11SPEAKERSo if you buy that multi-material feeder, will that work with their other bigger printers

46:14SPEAKERtoo?

46:15SPEAKEROr is that particular?

46:16SPEAKEROkay.

46:17SPEAKERSo then, so it seems like if you want to like buy a starter printer and don't buy a bunch

46:21SPEAKERof accessories and then if you're going to get into it, then move that one or move it

46:26SPEAKERdown the chain and then buy the accessories for the next one.

46:29SPEAKERRight.

46:30SPEAKERExactly.

46:31SPEAKERExactly.

46:32SPEAKEROkay.

46:33SPEAKERAt $500 there's the P2S and that's the enclosed one core XY system.

46:36SPEAKERThey just put this out late last year.

46:38SPEAKERThis basically replaces the X1C, which has been their workhorse.

46:42SPEAKERAnd this one will do that 10 inch by 10 inch by 10 inch.

46:44SPEAKERIt has the the four filament feeder and that's a great like workhorse printer in the bamboo

46:51SPEAKERlab ecosystem and their ecosystem, you know, it is locked in to, you know, mostly their

46:57SPEAKERsoftware.

46:58SPEAKERYou can use whatever filaments you want.

46:59SPEAKERBut you know, if you want to remote view it on the, using the webcam, you have to use

47:05SPEAKERtheir software.

47:06SPEAKERYou have to create an account with them, but they have like a great repository of models.

47:09SPEAKERCan you make time lapses and stuff?

47:11SPEAKEROh yeah.

47:12SPEAKERAutomatically make time lapses.

47:13SPEAKERThis is always my question.

47:14SPEAKERI mean, you get addicted to like opening the app on your phone and just remote monitoring

47:18SPEAKERyour prints.

47:19SPEAKERYeah.

47:20SPEAKERAnd you can send them remotely too, right?

47:21SPEAKERLike, you know, I'm not home, but that sounds like a bad idea.

47:24SPEAKERI don't love that.

47:25SPEAKEROh, I do it all the time.

47:26SPEAKERAll the time.

47:27SPEAKERRemotely remotely activate.

47:29SPEAKERAnd then by the time you're home, you have a, you have a print.

47:31SPEAKERSo so are you doing these around your kids or do you have it like in the garage or someplace

47:36SPEAKERwhere it's out of the way and you don't breathe it?

47:38SPEAKEROkay.

47:39SPEAKERYeah.

47:40SPEAKERIt's not about breathing it.

47:41SPEAKERI still want them touching it while it's printing.

47:42SPEAKERIt's hot.

47:43SPEAKERYeah.

47:44SPEAKERYeah.

47:45SPEAKEROkay.

47:46SPEAKERAnd then there was a printer that was released that's just shipping now, but they did a very

47:50SPEAKERsuccessful Kickstarter from Snapmaker.

47:53SPEAKERIt's called the U1.

47:55SPEAKERAnd this one is a four tool head changer.

47:58SPEAKERSo this multicolor, but it does really fast multicolor printing with no waste, basically.

48:03SPEAKERAnd it's 850.

48:04SPEAKERThey might've gone $900 at the Kickstarter price, those 800 bucks, basically under a

48:10SPEAKERthousand dollars.

48:11SPEAKERBut at that's, you know, enclosed printer, good build volume and this four color printing

48:17SPEAKERreally fast, really well.

48:18SPEAKERWow.

48:19SPEAKERSnapmaker.

48:20SPEAKERHow much is that one?

48:21SPEAKERI want to say like it's under 900, but it's like 850 or 899.

48:26SPEAKERThat's amazing.

48:28SPEAKERI mean, it seems like the thing that's changed is it seems like you can, A, there's a good

48:35SPEAKERpath on board that seems like you're going to get something that works and doesn't require

48:38SPEAKERa lot of futzing with and that you're going to get, like, if you, if you want to make

48:42SPEAKERstuff for shops or whatever, for an Etsy shop or for going to grab fairs or whatever, that

48:46SPEAKERseems pretty attainable now.

48:48SPEAKERDo you want to talk, can we talk about resin printers just for a minute?

48:52SPEAKERIs it, if you're, if you're starting out, is it worth even looking at them or is it,

48:56SPEAKERI wouldn't, I wouldn't introduce any kids to resin printing.

49:00SPEAKERAnd the thing with material safety, it's way more, way more dangerous.

49:07SPEAKERJust the footprint for what you need to have on your work bench for resin printing is like

49:12SPEAKERthree times as much as filament printing because you have the printer, you have the resin that

49:18SPEAKERyou need to store.

49:19SPEAKERThese are this liquid now, right?

49:21SPEAKERAnd then you also have to have the post-processing is the, is the messy part.

49:25SPEAKERAnd so to take a step back, resin printing works.

49:28SPEAKERThis is SLA resin printing, still taking a digital model, slicing into layers, but as

49:34SPEAKERopposed to being printed from the ground up on a bed, the bed is actually upside down.

49:40SPEAKERIt's on a plate, right?

49:42SPEAKERAnd that the plate moves up and down into a vat of liquid resin.

49:46SPEAKERAnd then underneath the printer is a UV light that blasts through a clear film onto your

49:53SPEAKERplate.

49:54SPEAKERAnd that clear film has a, separates it and a masking layer.

49:59SPEAKERSo this is like an LCD screen and that generates basically what parts to print and what parts

50:04SPEAKERnot to print.

50:05SPEAKERA positive and a negative, right?

50:06SPEAKERExactly.

50:07SPEAKERAnd these, and then this is all kind of benefiting off of cheap, you know, tablet LCDs in the

50:13SPEAKERstart and that's why you could have like 4k, 5k, 8k LCDs are all like tablet aspect ratios.

50:19SPEAKERNow they're using mono LCDs cause it really, they realize you don't even need color right

50:24SPEAKERin the LCD.

50:25SPEAKERIt's just an outline.

50:26SPEAKERAnd so these black masking layers, which are what, like high end video monitors, you know

50:34SPEAKERhow like Apple cinema displays or the high end production displays get really high brightness

50:38SPEAKERbecause they actually combine a black masking layer plus the color LCD.

50:43SPEAKERAnd so it can blast more light through and this is basically that.

50:49SPEAKERSo as opposed to having to draw the outline of every layer, you know, taking like a minute

50:55SPEAKERto draw your exposure time on the UV for the type of resin you're using can be like five

51:00SPEAKERseconds and you're curing a layer every five seconds.

51:04SPEAKERSo the prints are much faster.

51:06SPEAKERThe accuracy is much higher because the resolution of, you know, the XY resolution of the masking

51:12SPEAKERlayer can be really high.

51:13SPEAKERSo cause that's the defining, that's what defines the resolution of each layer, right?

51:18SPEAKERSo you know, then they can do anti-aliasing as well to smooth things out.

51:23SPEAKERThe plate, the accuracy of the build plate moving up and down is also, that's just step

51:26SPEAKERremover technology.

51:27SPEAKERAnd so it can be really fine, like 0.05 or five microns of layer height.

51:33SPEAKERAnd so what you get is really fast printing, really high fidelity printing for things like

51:37SPEAKERminiatures, but you're working with toxic resin that should never touch your skin, that

51:43SPEAKERyou should not be breathing in and that you're running for hours at a time.

51:48SPEAKERSometimes an enclosed box, but you know, without proper ventilation most of the time and definitely

51:53SPEAKERnot great to have just in open space in the house.

51:56SPEAKERAnd also the resin, because the resin's UV and oxygen reactive, like once you open the

52:01SPEAKERjar you have to kind of use it fast, right?

52:03SPEAKERYeah, there's lifespan for sure.

52:05SPEAKERI mean, you know, they'll all come with an expiration date, but I know people use resin

52:10SPEAKERway past expiration date.

52:12SPEAKERIt's more UV reactive than oxygen reactive.

52:16SPEAKERSo if you keep it in a cold area sealed, then you know, the bottle should last on time.

52:21SPEAKERHe's got to mix and stir them.

52:23SPEAKERThey also are temperature reactive.

52:25SPEAKERAnd so, you know, some of the innovations with resin printing is now the vats of resin

52:29SPEAKERare heated, right?

52:30SPEAKERSo I kept it a nice temperature and that helps with consistency and adhesions to the build

52:35SPEAKERplate.

52:36SPEAKERThe build plate stuff can all be, have different like textures on them for better adhesion

52:40SPEAKERas well.

52:41SPEAKERYou can't get away from scraping.

52:43SPEAKERSo you have to be scraping off this and that's a dangerous part because you're using a sharp

52:46SPEAKERscrape knife, but they're like flexible build plates that people can use for resin printing

52:51SPEAKERas well.

52:52SPEAKERThat you pop things off.

52:53SPEAKERYeah.

52:54SPEAKERDo you have to do post-print treatment on stuff to harden it up still?

52:58SPEAKERSo there's a cleaning process and a curing process, and this is where it's just really

53:02SPEAKERmessy.

53:03SPEAKERSo your resin print is done.

53:06SPEAKERYou lift it off the build plate, still dripping resin.

53:08SPEAKERYou're wearing a mask, ideally.

53:10SPEAKERMost people don't.

53:11SPEAKERWearing a mask, you're wearing gloves for sure.

53:14SPEAKERAnd then you got to go pry the model off the plate onto, into a washer.

53:20SPEAKERAnd so these companies all sell their own washer that you're using IPA or some type

53:25SPEAKERof washing fluid and that stuff is a consumable.

53:28SPEAKERYup.

53:29SPEAKERIsopropyl alcohol.

53:30SPEAKERJust to be clear.

53:31SPEAKERYeah.

53:32SPEAKERAnd you're washing and rinsing.

53:33SPEAKERAnd some people even encourage like getting a toothbrush or a brush in there to scrape

53:37SPEAKERoff any resin.

53:38SPEAKERAnd once it's rushed and dried, so you have to wait for it to dry.

53:43SPEAKERThen you put it into another UV oven.

53:46SPEAKERThat's sometimes temperature controlled or sometimes more often just like on the turntable

53:51SPEAKERwith the UV light.

53:52SPEAKERAnd then you got to cure it for a certain amount of time and different resins will cure

53:56SPEAKERat different rates.

53:57SPEAKERSo some resins, if you over cure it, it becomes too brittle.

54:00SPEAKERSome if you cure it too fast after washing, you get like a weird shine on it.

54:04SPEAKERSo it becomes alchemy.

54:05SPEAKERYou have your recipe book of like with this resin, here is my process.

54:09SPEAKERAnd after all that, you still have probably resins splashing everywhere and you got to

54:12SPEAKERwipe down and spray with isopropyl alcohol in your workspace.

54:16SPEAKERAnd it's really, really messy.

54:18SPEAKERWhen you use, and because this resin is UV reactive, the plastics can be very reactive

54:22SPEAKERtoo.

54:23SPEAKERSo if you use it outside, it's not going to last as long.

54:24SPEAKERYeah.

54:25SPEAKERYou probably want to code it.

54:26SPEAKERYeah.

54:27SPEAKERCode it with some primer or something.

54:28SPEAKERLike a clear coat or something.

54:29SPEAKERYeah.

54:30SPEAKERYeah.

54:31SPEAKERExactly.

54:32SPEAKERInteresting.

54:33SPEAKERHow do you handle waste?

54:34SPEAKERLike you can.

54:36SPEAKERYou're supposed to.

54:37SPEAKERSo, so resins.

54:38SPEAKERDoes this have to go to hazardous materials?

54:40SPEAKERIt should technically go to hazardous materials.

54:42SPEAKEROh no.

54:43SPEAKERYou can, you can filter out and reuse some of that isopropyl alcohol, but like resin

54:49SPEAKERshould not just go in a trash can and it should be separated and properly disposed of.

54:56SPEAKEROkay.

54:57SPEAKERShould be.

54:58SPEAKERThis is, this is the problem with these, you know, there was no regulation.

55:01SPEAKERThe companies crank out the printers and some, you know, they're not very repairable and

55:07SPEAKERthere's so, so much of these are commodity items now that, you know, they upgraded so

55:11SPEAKERquickly people burned out just buying printers and you know, I had at some point, you know.

55:17SPEAKERYeah.

55:18SPEAKERAt one point you were like, Hey, do you want a resin printer?

55:19SPEAKERI was like, no, I'm good.

55:21SPEAKERYeah.

55:22SPEAKERSo the, the, like when you're done with a print, what do you do with the residents in

55:28SPEAKERthe trade?

55:29SPEAKERJust dump it back in the bucket or in the, in the resin container or is that like, is

55:33SPEAKERthat just measure it carefully when you put it in so you don't have a bunch of resin leftover.

55:37SPEAKERYou know, you can, there are lids you can use to seal the, the, the vat.

55:41SPEAKERBut if you want to change colors, right?

55:44SPEAKERCause there are different colors of resin.

55:46SPEAKERThen you got, then you got to use a funnel and pour it back into the bottle and then

55:49SPEAKERpour.

55:50SPEAKEROh God.

55:51SPEAKERYep.

55:52SPEAKERAnd then you got to spray the, you know, spray the vat, clean the vat so you don't have any

55:54SPEAKERmixing of the resins.

55:56SPEAKERThat's why Formlabs, you know, which made the first SLA printers that we saw, the first

56:01SPEAKERconsumer ones.

56:02SPEAKERYeah.

56:03SPEAKERYeah.

56:04SPEAKERTheir whole thing is you just buy different vats and their vats become the consumables.

56:05SPEAKEROh, that makes sense.

56:07SPEAKERAre is the residence still expensive compared to the, the FDM plastic?

56:12SPEAKERYeah.

56:13SPEAKERYeah.

56:14SPEAKERI, it's like 25 to $30 a liter liter.

56:18SPEAKERWhat's a liter way?

56:19SPEAKERLike a half a kilogram or something?

56:20SPEAKERNo, it's, it's like 800, 800 grams or so.

56:23SPEAKERYeah.

56:24SPEAKERSo it's like, you know, you're talking about, you're still talking about mass and so I could,

56:30SPEAKERyou know, a 150 gram model you printed in FDM is going to be basically the same thing,

56:34SPEAKERsame size.

56:35SPEAKEROkay.

56:36SPEAKERSo, you know, the price is kind of comparable.

56:39SPEAKERYou're probably wasting a little more with the cleaning.

56:43SPEAKERBut it's one of those things that once you start a bottle of resin, you kind of want

56:46SPEAKERto get through it.

56:48SPEAKERYeah.

56:49SPEAKERAnd, and I mean, if you're doing really small fine detail stuff, it makes a lot of sense

56:52SPEAKERto do that.

56:53SPEAKEROr especially, especially if like, like one of the guys I watch uses these to do gears

56:58SPEAKERand stuff like that because they're, they're, they're predictable, they're mechanically

57:01SPEAKERthe same and that makes a lot of sense to me.

57:04SPEAKERAnd then the resin can be really strong too.

57:06SPEAKERLike there are some really strong resins, really hardened resins that require longer

57:10SPEAKERcure time, longer post-processing time with heat and light.

57:14SPEAKERAnd that's what, you know, a lot of these industrial companies use too, like just industrial

57:18SPEAKERresins.

57:19SPEAKERDoing mechanical processes, mechanical prototyping and stuff like that.

57:23SPEAKERYep.

57:24SPEAKERYep.

57:25SPEAKEROkay.

57:26SPEAKERSo last, last couple of things.

57:27SPEAKERWhere do you get print storm?

57:28SPEAKERAre you designing stuff yourself or you go to stores or their AI model generators?

57:32SPEAKERLike what's the process?

57:34SPEAKERThere's so much bad AI models out there.

57:35SPEAKERSo a lot of good rate repositories and like, because more people have printers now and

57:39SPEAKERyou know, it's, it's, it's like MP3 players.

57:42SPEAKERWhen everyone bought MP3 player, the, the, the avenues for getting MP3s just became,

57:48SPEAKERyou know, got real popular.

57:50SPEAKERIt turns out like media became cheap.

57:53SPEAKERSo Thingiverse is still around, right?

57:57SPEAKERRemember Thingiverse?

57:58SPEAKERMy mini factory, it was bought by Ultimaker and they just sold to my mini factory.

58:03SPEAKERSo we'll see how that goes, but Thingiverse is still free.

58:06SPEAKERIt still has an archive, all these models.

58:08SPEAKERMy mini factory is a great place to buy models of miniatures from creators.

58:12SPEAKEROkay.

58:13SPEAKERSo a lot of people who do the Patreon thing also sell on my mini factory.

58:18SPEAKERSo if you just want to get like one model or a handful or set of designs or something.

58:22SPEAKERYeah.

58:23SPEAKERAnd various different licenses too.

58:24SPEAKERYou know, if you want to pay more for license to be able to sell it at the farmer's market,

58:28SPEAKERyou know, you should do it the proper way with these places.

58:32SPEAKERModels is what Prusa runs in it, but it's not just for Prusa printers.

58:36SPEAKERYou can download the OBJ SEL files, the 3MF files, even the step files, which allow you

58:41SPEAKERto scale and increase different facets.

58:45SPEAKERAnd then you know Bamboo Lab has their own maker world, which you could access via their

58:50SPEAKERapp as well as the website.

58:52SPEAKERAnd that's makes it super easy to browse in the app and they have slicer profiles for

58:56SPEAKERtheir printers.

58:57SPEAKERSo really tap a model and say, I want to print this model at 10 of these on my printer at

59:04SPEAKERhome.

59:05SPEAKERGo.

59:06SPEAKERAnd you can do it from the phone.

59:08SPEAKERI've seen things lately pop up some.

59:11SPEAKERYeah.

59:12SPEAKERIs it problematic?

59:13SPEAKERIs there scene drama here?

59:16SPEAKERI don't want to get too much into scene drama.

59:17SPEAKERThere are certain places that, you know, if you just Google 3D models, I think there are

59:21SPEAKERa couple that I didn't mention that I'd rather not purchase from or get from just because

59:26SPEAKERof widespread piracy or just like bad policies.

59:34SPEAKERSo I'd say go with the ones I recommended.

59:36SPEAKEROkay.

59:37SPEAKERGood to know.

59:38SPEAKERGood to know.

59:39SPEAKERIncreasingly, there are like AI models and you see bad AI art as the thumbnails that

59:45SPEAKERtrick people because a lot of these repositories reward people who upload like if they're affiliated

59:50SPEAKERwith Bamboo Lab right by Maker World, they're incentivized to people are incentivized to

59:55SPEAKERget people to download their models because the more models and the more people vote you

59:59SPEAKERand donate or whatever, the more credits you can get to redeem fulfillment or even printers.

1:00:03SPEAKERRight.

1:00:04SPEAKERSo you get a lot of people just spamming or stealing in different places.

1:00:11SPEAKERAnd it's, you have to kind of have an eye for, you want to like the best models have

1:00:15SPEAKERgreat photos of the actual actual model of the print.

1:00:19SPEAKERYeah.

1:00:20SPEAKERAlmost all of these places have a section where people can share images and settings

1:00:24SPEAKERof what they've printed from this model.

1:00:27SPEAKERAnd you kind of vet that way.

1:00:29SPEAKERThat makes a lot of sense.

1:00:32SPEAKERIt's funny.

1:00:33SPEAKERI see a lot of people complaining about the AI model generators as being like easier to

1:00:38SPEAKERjust learn to do it yourself than to try to clean up something that was janky and made

1:00:41SPEAKERby the AI generators.

1:00:46SPEAKERMaybe we'll get better, but like, you know, there are a lot of places where like you can

1:00:48SPEAKERtake a photo, upload a photo and it'll just kind of infer and get something that looks

1:00:53SPEAKERright from one angle, but never right from the other angles.

1:00:56SPEAKERAre you, are you like, like what tools are you using to change your touch up stuff?

1:01:01SPEAKERLike if you want to jam a wall mount on something, are you just opening it up in blender and

1:01:05SPEAKERmelding them together?

1:01:06SPEAKEROr do you have other tools you use for that stuff?

1:01:09SPEAKERTinkercad.

1:01:10SPEAKERTinkercad.

1:01:11SPEAKERWeb based.

1:01:12SPEAKERYeah.

1:01:13SPEAKERYou can upload models.

1:01:14SPEAKERYou can do Boolean operations.

1:01:15SPEAKERYou can merge meld stuff.

1:01:16SPEAKERAnd yeah, it really works.

1:01:17SPEAKERVery cool.

1:01:18SPEAKERWhat's the best thing you've printed lately, Norm?

1:01:22SPEAKERThis stuff for kids, like, you know, printed a bunch.

1:01:25SPEAKERThere's a, there's a three, a modeler who runs a patron called Matt Meyer makes, and

1:01:30SPEAKERhe does really great multicolor characters and I've been doing a ton of his stuff to

1:01:35SPEAKERsend with the kids to school.

1:01:37SPEAKERSo the backpacks of key chains, like charms and stuff charm.

1:01:40SPEAKERExactly.

1:01:41SPEAKEROh, that's fantastic.

1:01:42SPEAKERWell, cool.

1:01:43SPEAKERThank you.

1:01:44SPEAKERThank you so, so much, Norm.

1:01:49SPEAKERchannel or send an email to techpottycontent.town and I'll circle back with Norm when we get

1:01:53SPEAKERto the questions at the end of the month and if there's specific stuff, where should people

1:01:57SPEAKERfind you?

1:01:58SPEAKERWhat is the plug section?

1:01:59SPEAKERTested.com?

1:02:00SPEAKEROh, they can just go to Tested, tested youtube.com/tested.

1:02:03SPEAKERI think I'm on Blue Sky, but I don't know my Blue Sky account.

1:02:06SPEAKERYeah.

1:02:07SPEAKERI think you're, you're nchan.bsky.whatever.
