[@davidf2281]

Joel has a great interviewing style -- engaged and enthusiastic, guides the conversation but lets his interviewee talk without interrupting. Lovely stuff 👍

[@dwang085]

He really is fantastic!!

[@joetkeshub]

that hasn't prevent his audience i.e. followers number from shrinking since a while...

[@mjdarby714]

It's clearly evident in the video that David is not only incredibly knowledgeable about this process, but enthusiastic and excited about it. So refreshing to see someone in manufacturing who takes genuine pride in their work.

[@3DPrintingNerd]

David is SUCH a good human. Wicked smart and VERY excited about this tech!

[@dvomang]

I’m shocked you didn’t mention dental 3d printing with ceramics more than just in passing. We are literally already doing this. There are thousands of dentists printing ceramics everyday. I have patients with 3d printed ceramic crowns in their mouth right now. They show an animation of DLP vs SLA and it’s courtesy of Sprintray who is the biggest dental 3d printing company.

[@daviddiegel1239]

The 3DCERAM system is making Dental implants, Abutments, Crowns, and Orthodontic brackets in production now. That is for another show. We talked about it more but that was edited out. The use of a large production system like this would be for mass customization where we print 2,000 unique parts in one printing for many different patients. This would be more for the parts that require high temperature sintering like implant screws and abutments that are customized to the patient. This is the new normal that people will come to see in dental labs soon.

[@MakersMuse]

You know the equipment is serious when the engineers choose granite! I've only seen a couple sexy CNC granite machines and this is one of them... 😍

[@robertheinrich2994]

there was a CD manufacturing site in salzburg/austria (maybe it is still there) by sony, and they showed their CD manufacturing system, essentially a CD burner that used a 1.5t granite block as rest. on another note, granite tables are actually fairly common in chemistry if a scale is required that can measure down to the microgramm-level. they are allergic to vibrations. and in 3d-printing, a simple concrete slab is a recommended accessory that is insanely cheap.

[@twoheadedpanthr]

A lot of the newer cnc grinding machines use epoxy granite for the machine bases since they're super good at absorbing vibration.

[@Jessterrr]

I've only seen granite used on machine tools in lab settings. It was cool seeing it used on a 3d printer.

[@davidtobin]

You would absolutely LOVE this machine!

[@hardwareful]

yeah, but the precision is in the tens of µm.. it really doesn't add up, except for bulk mass and temperature stability.

[@CanuckCreator]

Been waiting on this video since you teased some of it on the livestream a few weeks ago, great to finally see it!

[@FilamentStories]

So amazingly exciting what the future holds and seeing 3DCeram keep Mini Joel and future space travelers safe. Love it!

[@woodwaker1]

Thanks for this continuation of serious 3D printing - many of us hobbyists want to see how additive manufacturing is changing so many processes

[@Jessterrr]

Nice job finding industrial 3d printing content that's really different and interesting. Print ceramic objects using resin seems so strange. I always dismissed gyroid as overly complicated and unnecessary but it sounds perfect for heat shielding.

[@ScuffedEngineer]

They've done it decades before in gel casting. Just change the polymer to a photosensitive and you can print.

[@VAXHeadroom]

17:50 The Space Shuttle Columbia disaster in 2003 was NOT the result of a faulty heat shield (which implies that either the design or implementation of the heat shield was not correct). The heat shield was hit by debris from the external tank. The heat shield was not designed to be hit by debris (which was fine). The TANK insulation - impregnated with ice - failed, broke up, and hit the heat shield creating a very large hole. I suppose you could say it was a FAILED heat shield, but it failed because of a situation it was never supposed to see... (yes, I know, space nerd being picky...)

[@davidtobin]

Well, that's just it. This material is far stronger and more efficent. If the same thing occured with this, the incident would not have happened.

[@VAXHeadroom]

@@davidtobin a cubic foot of ice at 100s of MPH slamming into this material? Probably would still shatter. BUT: it wasn't the main tiles that were hit on the Shuttle, it was the carbon reinforced material on the wing leading edge. So not a straight comparison at all.

[@MarcelHuguenin]

Great video Joel, enjoyed it a lot!

[@hazonku]

Very cool to see real companies out there making this finally happen. It's just a natural fit for the technology. I know much of the focus here was on commercial spaceflight as that makes sense for the Mini Joel demo but there are numerous terrestrial applications well beyond just the chip manufacturing example mentioned. This technology can support a vast number of other industries and manufacturing processes.

[@sidekick96734]

Any deformation concerns in the finished product as the size of the object increases? Is the amount of shrinking from print to sintering predictable? Just curious.

[@brine1986]

This episode is 2000 degrees awesome! Cool engineering and space thats what I love 🎉

[@theflyinggrip]

Freaking fantastic episode my friend!!! Joel, seriously...thanks for putting out this crazy informative and entertaining content. I really enjoying actually seeing cutting edge tech and how its being used. Enough of this type of content just doesn't seem to make into the general publics eye, at least I don't see it. Cheers!

[@mikeconnery4652]

Excellent interview and information

[@fmtdamian]

As an engineer who work with high temperature sintering ceramic I must say It's awesome technique to produce special ceramic materials 😁😁👍👍

[@TheZombieSaints]

Hasn't Integza been using similar stuff to this for a while now? You have to burn the epoxy out but he's made rocket engines at home with the stuff he uses.

[@tecnobs3d]

Interesting technology. Awaiting more similar videos

[@TheNextDecade]

I used to work on machines like that too, except they were big enough to fit a 6'5" guy on the build plate. massive tanks of resin. SLA is wild.

[@hen3drik]

When the prices for the heat tiles were revealed, I thought I had overestimated. That's when I burst out laughing briefly. 😅

[@Breakfast_and_Bullets]

"Serenity's got more than a few ceramic parts in her."

[@jph290]

This is so cool. They are like an hour away from me!

[@g.s.3389]

amazing and interesting video :)

[@MrGerhardGrobler]

I am actually looking at 3D printed single use nozzles for my motors. But the other option is ceramic nozzles. Very interesting, as I am a fan of space before I got into 3D printing. Great video.

[@davidconner-shover51]

This was my first thought; could you do thruster nozzles and chambers??!!

[@stevehanwright481]

Great work mate

[@westonw311]

It's wonderful to get people more exposed and educated on technical ceramics. For niche applications like this or for prototyping, it's a great technology to have access to. However this will never fully replace traditional ceramic processing methods for actual full production parts, and is generally limited to certain types of ceramic materials. One thing not touched on that would be neat is the actual ceramic powder that goes into making the "slurry" that's being laid down. The particle size distribution and control is incredibly important. Awesome video!

[@ScuffedEngineer]

The slurry part is fairly easy, ceramic slurries have been made for a long long time. Same knowledge can be transferred from traditional non-technical ceramics and even the older knowledge on technical ceramics.

[@C4reful]

Cant wait for my superthin compact gyroidinfill 3d printed ceramic pizza oven! Forget spacetravel, thats where the real money is!

[@3DPrintingNerd]

PIZZA! YES!

[@ScuffedEngineer]

If it's made from corderite it would be very simple.

[@MakerDaveBagnall]

This is pretty fascinating, I do a lot of metal casting into high temperature silicone moulds. Printing a casting mould with this technology would be awesome!

[@retromodernart4426]

You can print ceramic resin with a good MSLA LCD printer, you need a kiln to burn it out for using as a mould afterwards, the issue of burning out the LCD is not true if one uses proper methodology to print the ceramic resin, 3 bottom layers, bottom layer exposure time ~6 seconds, normal layer exposure time only needs to be 2 seconds, with certain ceramic resin. The only problem is the resin is like plaster of paris, but I've printed ~6 hour prints with it, no problem.

[@daviddiegel1239]

@@retromodernart4426 I would love to know if you used a fully loaded ceramic like Zironalite or Alumina or a more lightly loaded ceramic like porcelain or lightly loaded ceramics? I love that you have accomplished this with a MONO SLA. Did you use a Phrozen or other printer?

[@prouttralala]

i see a perfect use for this product: heat shield for Rotating detonation engine

[@mutlubasdas]

Thanks for explaining vestige :)))

[@bobasawrus]

Thankyou for this wonderful presentation. You did a great job explaining the process, and nailing the value statements. My son and I are huge fans of 3D printing, and the mind-blowing potential of these new technologies. We have 2 FDM printers and are looking to get our first resin printer! I am curious how you characterize the shrinkage that takes place with the curing.

[@iankphone]

Columbia was not lost due to a faulty heat shield. I'd also like to know how precision parts are made/designed when the part shrinks in post processing.

[@retromodernart4426]

The shrinkage is known and linear, the model is adjusted to take the shrinkage into account so the final part is accurate.

[@slevinshafel9395]

16:00 that nice.

[@winstonsmith1457]

Hi. I wonder if it's possible some kind of aerogel-ceramics.

[@stevesloan6775]

The Russians had it right when they used oak wood as a Heatshield on their space shuttle. The carbon of burnt oak is incredibly strong and heat resistant. Like the ships of yesteryear were made of wood, so to are the spaceships of the future.

[@CUBETechie]

Can it used to for heat batterys too?

[@zickiea172]

What if you did lateral laser with a “periscope” to the layer at rear level ?

[@David-yo5ws]

With the advancement in mini-sats, I could see bespoke ceramic heat shields allowing specialist 'clustered sats' in orbit, gather data and one by one returning to earth to be processed as needed. Sort of like a dash-cam that records an incident Then re-cycle on the next ride-share. No wonder David, Joel and quite a few others, are excited.

[@TheBrandonhaskell]

Oh man! I live in Grand Ledge. Would have bought you a beer if I knew you were here!

[@TheMadtownman]

It’d be cool to make it double hulled with gyroid in between. It could act as a whipple shield kinda

[@custos3249]

Amazing how we started with stone tools only to come back to them

[@hanslain9729]

A silicone spatula recoats a pan as you use it?

[@3DPrintingNerd]

If you’re very, very careful :)

[@tsclly2377]

Where are the inter locking lugs and the surface inter lockers?

[@robinmartin4464]

Joel goes to space! cue the starwars music.

[@joshuahansen5486]

Remember 3D printer enthusiasts everything that goes from a liquid to a solid can be 3D printed

[@lovro4744]

Great technology, but dam, we need to start building powerplants. The future is hungry for energy.

[@PiDsPagePrototypes]

Plenty of desert property where Solar Arrays can sit, making nice shade while waiting for Solar Electric kilns to cure the prints. Mamosa anyone? ;)

[@scientificidiot4165]

20:00 my brain: break it! Crush it!! Throw it!!! Do not let me near it

[@haitianrefugee8454]

Can you make ceramic body armor with this technology?

[@PiDsPagePrototypes]

The options for Impractical Armor,.... that actually works ! 😂

[@jamesray9009]

[@olivier0092]

Ultimate vector laser 😂

[@aprintedworld]

Frickin’ Lasers!

[@slevinshafel9395]

15:00 If can be automatized no worry about it. But being fragil in rocket cant work.

[@davidgutting4317]

I would love a consumer level version of this printer for making food grade utensils and goods. Automotive products made from ceramics rather than metals is also very attractive,

[@daviddiegel1239]

We have a FFF or FDM printer that is a bit less expensive and simplified for use. You will still need the de-binding and Sintering kilns however and a place to run them. That is not something you are likely to do in a garage or basement.

[@davidgutting4317]

I do prototyping and product design and build a lot of my own equipment when I see a market opportunity so my basement/garage is a little better equipped than most. That said, ceramics are really tricky dur to the amount of energy that needs to be put into them and the amount of shrinkage that has to be calculated for. Do you have enough power and focus in a fiber laser to sinter each level and skip the binder and kiln time and go straight to fused / cured solid ceramic?

[@MakerBees333]

That’s crazy hot 1600c is hot enough to MELT granite! 😱

[@robertheinrich2994]

honestly, I would have loved to see a mini joel made of ceramic with gyroid infill tested to destruction. I can only imagine that this would require some serious force.

[@brightlee9437]

It appears to me that the structure of the 3D print object will be limited as the laser starts from top to bottom where the already printed parts will block the unprinted parts.

[@daviddiegel1239]

the part descends and the next layer is printed on top of the printed part.

[@radioactivesdesigns3554]

Next up: 3d printed aerogel

[@PiDsPagePrototypes]

"Frozen Smoke" would be a great name for a Aerogel printer company.

[@slevinshafel9395]

24:05 But that gyrod must be improved. Because air inside must be closed and not free walk around. I mean a good insulator is a soap bubble but made of ceramic. 3D printers can do it but not this one because the fill inside need to be evacuated. But they can use the brick (like stairs) form to make it. Print a wall brick where the air camara of surface heat dont touch the air camara close to the spaceship. and of sides can evacuate the resin easly. Mean time i was writing this i was think in powder ceramic print but have the same problem. The solution can be calding materials but must be more smaller than actual indutrials ones.

[@slevinshafel9395]

the surface inside dont care to much. and the outside can be treated in sumerged bath and polish it.

[@techforthedisabled9514]

Has anyone 3d printed a Antikythera mechanism

[@Wm200]

They as well print teeth with 3d printers.

[@Everfalling]

the demonstration toward the end doesn't really mean much as you could have set almost anything in front of the aluminum to keep the aluminum from being directly heated. you coulda put a normal brick or even a chunk of 2x4 on it and it'd have done the same thing.

[@darren990]

i bet they cost a bit .bet he got contracts with space x and the DOD

[@yotortellini]

I think he meant Masked SLA instead of mono sla

[@rcmaniac25]

Awesome! And you nailed one point I've said to people: it's real nice to come up with all this tech and systems... on Earth. But what? We're gonna send all the materials to the other planet/moon? We need a way to make the stuff elsewhere from the materials we find there.

[@PiDsPagePrototypes]

Small ceramic engine blocks and cylinder heads, printed instead of cast,... this could be interesting for vehicles that need extremely low mass, such as ultralight aircraft, motorbikes, racecars, drone & RC Aircraft. Then flip the use to pumps, and there's designs for lightweight equipment to move cryogenic fluids around, such as refueling space stations and Starships, or resources for life support, LOx, Water, waste management. Doesn't look to be prices on the website, which means the products are aimed at Corporations, not home builders. Volumne goes up, prices come down, processes get copied,.. So, about 5 years till we see consumer grade options under US$1000.

[@ScuffedEngineer]

It's mostly the lasers that need to come down in price, the rest can be easily scaled for costs. You can do direct ink writing for ceramics rather cheaply though.

[@jerbear7952]

That machine looks like it is made out of solid $100 bills

[@3DPrintingNerd]

Ha! That makes me think “there is money in the banana stand”

[@nerddub]

"like countertop granite" no, like surface plate granite. You wouldn't cut your kitchen counter up for precision metrology or machine ways.

[@3DPrintingNerd]

I mean, maybe not YOUR kitchen, but mine - let’s do it. Heh. :)

[@nerddub]

@@3DPrintingNerd lmao fair enough, probably just salty becuase my counters are made of some sort of horrible plastic sheet

[@anon_y_mousse]

That first info card has a mistake where it says "high templates" instead of "high temperatures". It might be a waste of such a machine's talents, but I'd love to see how complex of a print they could make as an art piece.

[@cptairwolf]

Jesus the cost of making these is astronomical (pardon the pun).

[@Scott_C]

Stainless Steel is the only way to fly. Aluminum is just asking for failures. EX: 23:00

[@ThomasAndersonbsf]

man you better at least give a shout out to Integza since he was using ceramic printing to make rocket parts over a year ago.

[@dirtyqsick]

One thing. The Earth is flat.

[@anon_y_mousse]

That's a dead meme. We all know that no one seriously means that.

[@MrMegaPussyPlayer]

21:38 Or, and hear me out on this, you could launch your spacecraft without heat shield and save the weight (and several thousand tons of fuel from earth) and just retrofit it on the return trim. With all materials sourced outside of earth.
