The fact that they could test how the printing in "zero g" would turn out, simply by printing in a "zero g" nose dive of a plane, because the print times are THAT fast is outright amazing...
I'm thinking that with print times measured in seconds it's feasible to employ some sort of tracking to follow the print as it rises and keep the projection aligned. A smart approach to printing the object might allow finished portions to rise above the surface as the rest is printed. And of course supports are probably an option. Here's an idea! Magnetorheological additives in the fluid, use an electromagnet to make the stuff more viscous, then turn it off and it returns to its base state. So many possibilities.
I love they're making this open source. As we've seen in 2D printing, the researchers come up with a cool tech, and then when the garage tinkerers get their hands on it things really take off.
forreal, i was so sure that this was going to be a proprietary thing where the research group would license it out to pay back their student loans and shit, but no, open source, that's amazing
Hey Joel! I was one of the engineers and the operator of the 3D Printer (Manufacturing Device) as well as the ceramic resin 3D printer (T-CMM) on the International Space Station a while back. Love seeing this tech! Knowing the current issues facing additive manufacturing in a micro-gravity environment, this is absolutely a game changer if they can work out a quick and easy post processing method that is space (as in volume) efficient and space environment friendly.
I definitely believe you that you’re an astronaut (in the public sense of “someone that goes to space”. Don’t know if your job is actually called that). No sane human being would use “microgravity environment” when talking about being on a space station.
@@EXAPHI I’m a little confused what you mean… Are you saying you where operating the 3D printers that where/are on the space station remotely? That’s the only may I see that makes sense.
Man, look at what Stratasys is doing with full color, multi material printing. Not to mention the new core xy printers that are doing fdm at insane speeds. I think the novelty of 3d printing has worn off for a lot of hobbyists, but the current innovation is insane. Can't wait for all the tech to trickle down to consumers.

I can't believe I missed this at OpenSauce, but to be fair I was running my own booth too. That is absolutely fascinating. I want to try this at a large scale, like in a big 50 gallon acrylic barrel with a movie projector.
Oh man so sad I missed this, was at OpenSauce (showing some custom made camera rigs I built in my garage) but wish I had more time to get around to everyone elses booth, so glad you were able to showcase this!
6:28 did he say 10 years off as the guy is pulling the mic away!? When will the project go up to the ISS as the ISS is going to be planed to be retired in 2030
I saw this like ten years ago! The earlier versions used multiple projectors; in addition to the one on the side there was one above and below. I am very excited to learn research has continued, the device has improved, and it's going open source! I hope the 3d printing community grabs this and runs with it. Sub-minute prints would be worth the hassle of SLA printing.
I had a similar idea a few years ago and I am happy someone did it, just my concept was more focused on using 2 sources of lights at a 90° angle, and crossing lights would create heating points. It wouldn't have to rotate.
"all at once" is a bit of a misnomer. The layers are applied in a rotational direction. The reverse scan anaolgy is more accurate. I am impressed the fluid is solidifying in the middle of the container and not on the outer edges. That type of solidification control is the real star of this process. Another question is whether the excess fluid can be reused. I would assume some of it as partially solidifed like current resin exposed to UV and we have to strain it to store and reuse.
The fluid is solidifying "in the middle" because these points ("voxels") are receiving the laser light all the time. So they heat up until they harden. The other points in the resin do not receive the laser light all the time, due to the vial rotating, so they do not heat up enough to harden. This is how the solidification in controlled. For example a point near the edge of the vial is rotating fast. It will only briefly pass in front of the laser, so it will not have time to get hot enough for the resin to harden. The trick, naturally, is to make sure that all the points you want to harden receive the laser light all the time, and as the vial is rotating, you must constantly update the image you are projecting.
Absolutely amazed by this technology! It's truly refreshing. This innovation is set to revolutionize the market, just as LCD and FDM have. I'm curious, are there any LCD printers that can match this speed for such volumes? Does anyone have insights? Also, printing larger volumes is certainly a challenge.
finderone 136？how about this printer?How accurate is it? I have a 3D printer, but its accuracy and volume it prints are no longer enough for me. I'm thinking of a new and better one.
Awesome! I remember going to ERRF 2019 and Adrian Bowyer was going to be a keynote speaker. He discussed this being an interesting new method to do 3D printing, though questioned ability to do some sharp details and lamented the use of resin (which still requires careful handling with gloves and all). He proposed using an alternative material (which they were supposed to be in the process of testing candidates) that could be formed with electrodes on the outside of the container... Back to the point: this is still an awesome process, love that there's a plan to make it open source, and will be curious to see where this goes and alternatives (like Bowyer's project) that do something similar.
From my interpretation of how he's explaining it, it feels like an analog of the the way string art is made, but using light instead of string and with a Z axis as well. Areas where you get more intersections over time are more likely to polymerise. I might be wrong, though 😁
It seems to me that they use light density with a rotating 3d model with an "xray" shading rotating in sync with the printing vase. So the density of light will be the same in each point of the resin. Not clear if they are pulsating slices of the 3d model or just projecting it all at once.
the possibility of room temperature superconductors, and a massive leap in life changing 3d printing technology in just a matter of days... man, what a time to be alive!
Im a senior (pre Donkey Kong ) software architect, we are working with some machines for hip and knee injuries, we have been discussing making some internal scaffolding to help recovery. Amazing to see CAL tech going open-source! It's a huge leap for research communities. Im picturing us integrating our TensorFlow models within an Anaconda environment to manipulate STL files which opens a realm of possibilities for customized tissue support. Thanks for making this revolutionary tech accessible and fueling innovation!👍
very cool! I remember working on a project like this in 2018, I was at a large Canadian 3D printing company and couldn't get them to understand the concept lol
Man, I super regret not stopping by the booth to take a closer look at this. Really neat stuff. Makes me wonder if rotating the chamber in more than 1 axis might provide even better resolution since I assume you can only beam through the same media for so long before everything in the way solidifies.
Seems like the entire vat of resin is "spent" after every print and has to be tossed if I understood how it works correctly, wish they talked more about limitations and downsides tho. I think it can only do solid objects too, nothing hollow so its got some insane print speeds but I have a feeling its very limited in what it can actually print...
What I found funny is that they are looking to use low viscosity resins when in other photopolymerization technologies the look exactly to use high viscosity resins. As they are way stronger in terms of mechanical properties (generally by adding fillers) and have a way more chemical resistance.
Possible idea. If you want to print with low viscosity in gravity, have your vial on a plate that can magnetically suspend a small ball bearing or something similar and build around that. Not sure if that would actually work but maybe worth looking into.
It seems like they could run it faster and avoid strings if they spun the projector around the vial instead of spinning the vial. The printer would be more complex, but I wonder if it would be worth it to avoid dealing with inertia
The projector needs power. If powered by a power cord, the cord would get super twisted. If powered by a battery, that'd make it even heavier than it is. Swinging something heavy in a clean circular motion with such a large radius without wobble is so much more difficult than spinning something on its axis.
@@hughobyrne2588 true. It would probably be worth the extra complexity with a larger vat though. Because of inertia, the larger the volume, the slower it would have to rotate.
This is incredible! What a beautiful, novel idea. Also, the direction they have for the future sounds so promising and wonderful. Human ingenuity really blows me away. That’s how we have progressed as humanity. All the best to the team! Can’t wait to try it myself someday :)
Seeing your video has 150k Makes me smile. Knowing the 3d printing community is expanding in a healthy way. Also thanks for keeping us updated with new technologies coming out every now and then
Very cool - but I suspect that all resin that's left over is ruined because it will have been exposed to the curing light. Obviously not enough to cure it, but probably enough to make it unpredictable in a second usage...?
I talked to these guys at open sauce, but they disappeared right after I talked to them and didn’t see them again. It’s a fascinating process though. Those Lawrence Livermore/Berkeley folks are pretty smart
This is a wonderful and HUGE development in the tech. Especially the bio uses. Imagine if they could bio print parts in a hospital for patients using their own MRI data? Wild!!
Woah... That biomaterial application is really, really promising. Organ printing would be an actual whole other application for the space industry that could potentially be done profitably. Quite a remarkable potential addition to the handful of already viable manufacturing avenues. Congratulations to them that they are involved in such a fascinating and potentially relevant technology.
Up the projector count to 3 to improve quality and production speed. From the bottom, side and 45° off from the top. Probably work great for making lost cast mold rapid prototyping
this is the most insane thing I have ever seen and it makes so much sense, resin printing is about to radically change at least in the next 10 years and calling this magic is NOT clickbait
Would calling this 4D printing be more appropriate, it seemingly surpasses 3D printing, and would make the technologies clearly distinguishable in speech without extra acronyms.
I was merely impressed until the end of the video. Open source!? Holy... 😲 This means formulations will be open source to!? This is beyond impressive, this is a game changer!
Makes you wonder, given the current 3d printing machines we have rn, which methods and mechanisms of printing under what gravitational pressure would produce the most effective prints (integrity wise)
for people having trouble understanding it, it's actually really simple. it's just a projector projecting a 3d model that is rotating at the same rate that the resin is rotating. it's very clever and elegant.
From all I understand the first thing the light touches is going to be the thing hardening first, so, like, the liquid right next to the wall will solidify first and quite evenly (because it is spinning) How does Like How does depth information be transferred, via a single projector, with a single point of view of the object? Us humans and, a lot of animal for that matter needed both of our 2 eyes to extract depth info
This is an interesting approach to having a process optimized for use in micro/zero G environments. It would seem that if you wanted to use this here on Earth, you would still need a support structure. I could see something like the part being constructed around a thin metal pin might be all you need to tweak the process.
The viscous resin they use prevents easy flow, even when the projector light is heating things up. The resin itself acts as a support structure because print times aren't long enough to heat the resin enough to make it flow. This is not the absolutely weirdest method of supporting a print I have seen.
According to my calculations the "cure through" dose needed would negatively impact the part accuracy... or if you tuned the absorptivity of the resin to get decent accuracy, you would be left with large radial conversion gradients in your parts... interesting chemical engineering problem 🤓
I'm curious about what kind of resolution this can print down to. Like can it print small gears or 'build in place' mechanisms with break away supports... or is it only capable of printing solid objects?
Resolution would depend on two-ish factors - X-Y resolution of the projector being used and its contrast rate. The brighter and darker that the image being projected can be, the clearer the details along the projection axis of each slice can be. There are a bunch of tricks that can be done to up the resolution, for using collimating lenses so all the light striking the resin is parallel, to using some kind of laser optics on (what I assume) is a DLP reflector. An even slightly powerful UV laser that could project a beam roughly the size of the projection element, routed through optics that first magnified the resulting image and then re-collimated the beam path so that all of the light hit the resin dead-on would make the features as sharp as is reasonably possible. At that point, it's really a matter of resin chemistry. I lie, you can get sharper if you want to start playing with weird split-beam quantum effects and special polymerization chemistry that requires two photons to hit the polymerization molecule at the same time. But at that point you're talking about a process so delicate that you would need to do it in a chip fab's clean room to ensure results. Maybe someone needs resin thingies that can't be made any other way with super-duper fine details, but I doubt that they need it enough to invent it.
1:45 instead of rotating you can use 6 laser projectors to make the image? How you solidifie the inside? This in Space is better because no need of suport. Nice tech.
this is amazing. I might be way off but the only way i could see this to be possible is if you have a beam of light that gets converged to a focal point and in that focal point the energy density is high enough for it to solidify.
This is awesome and mind bending, they need to have this calibrated so good, and take into account scattering, reflection, refraction, energy absorbtion etc.to be able to polymerize only the intended volume. But I believe the surrounding polymer gets compromised and cannot be used a second time, therefore for the moment this will be quite a wasteful process.
Great interview! Calling it lithography obscures the fact that it uses "reverse tomography" which is the brilliant insight that makes this revolutionary technology possible. Thanks for including links. The bioprinting aspect is exciting when done in zero-G and I'm eager to see the experiments and their results.
This is a potentially revolutionary process, it could very well be the foundation for (and I use the term cautiously) a replicator type manufacturing process.
I think this is how they treat cancer with radiation. To minimize the effect of radiation on the healthy cells, they move the radiation source around while directing it at the cancer so although healthy cells are being hit with radiation, it’s all concentrated on the cancer
This is pretty amazing. I can imagine there will be some limits to geometry, but the print speed is really impressive. This really fills the gap where layer resin printing is too slow and injection molding is too expensive.
It was an absolute pleasure having you stop by our booth and to introduce you to our technology in person, thanks Joel!
Your enthusiasm is contagious, man! Awesome job presenting+communicating!
Your freaking awesome cant wait what this technology looks like in 5 years
Absolutely awesome and your overview of it was easy for me to understand
holy moly... what an amazing idea! Never thought of it but definetly looking into building one! Thank you Taylor and team for developping this. And Joel of course for the vid ;)
can't you use a stem to prevent it from moving? if the print is attached to the bottom it should work pretty well with minimal deformation?
The fact that they could test how the printing in "zero g" would turn out, simply by printing in a "zero g" nose dive of a plane, because the print times are THAT fast is outright amazing...
I'm thinking that with print times measured in seconds it's feasible to employ some sort of tracking to follow the print as it rises and keep the projection aligned.
A smart approach to printing the object might allow finished portions to rise above the surface as the rest is printed. And of course supports are probably an option.
Here's an idea! Magnetorheological additives in the fluid, use an electromagnet to make the stuff more viscous, then turn it off and it returns to its base state.
So many possibilities.

This is incredibly amazing man, cant wait to see what you do in the next 10 years with this!
It seems like they could run it faster and avoid strings if they spun the projector around the vial instead of spinning the vial. The printer would be more complex, but I wonder if it would be worth it to avoid dealing with inertia
The projector needs power. If powered by a power cord, the cord would get super twisted. If powered by a battery, that'd make it even heavier than it is. Swinging something heavy in a clean circular motion with such a large radius without wobble is so much more difficult than spinning something on its axis.
@@hughobyrne2588 true. It would probably be worth the extra complexity with a larger vat though. Because of inertia, the larger the volume, the slower it would have to rotate.
Wow!
i ran across this research paper in 2019!
great to see some development!
absolutly love this technique!
keep up the good work!
I'm ecstatic, I'll be building one immediately
This technology opens up some amazing possibilities - so happy to hear it will be 'open source' ! high five!
Jaw-Dropping 1000%
This just changed my mind about 3D printing.
Insane technology, and they are going to open source it. Can’t wait for the future!
I remember reading about this in 2013 good to see it coming to fruition.
This is incredible! What a beautiful, novel idea. Also, the direction they have for the future sounds so promising and wonderful. Human ingenuity really blows me away. That’s how we have progressed as humanity. All the best to the team! Can’t wait to try it myself someday :)
I remember walking by you guys filming this video. Really cool to see how that printer works in depth.
This is truely a disruptive innovation in 3D Printing... Amazing
Seeing your video has 150k Makes me smile. Knowing the 3d printing community is expanding in a healthy way.
Also thanks for keeping us updated with new technologies coming out every now and then
Thanks for watching! ❤️
I am really glad youtube recommends this video to my feed.. it's really cool
Glad you enjoy it!
This about how far we have come with printing in the past 10 years. The next 20 will be insane
Very cool - but I suspect that all resin that's left over is ruined because it will have been exposed to the curing light. Obviously not enough to cure it, but probably enough to make it unpredictable in a second usage...?
Most americans can't afford the ambulance to the hospital, they ain't getting a space organ
I talked to these guys at open sauce, but they disappeared right after I talked to them and didn’t see them again. It’s a fascinating process though. Those Lawrence Livermore/Berkeley folks are pretty smart
This is a wonderful and HUGE development in the tech. Especially the bio uses. Imagine if they could bio print parts in a hospital for patients using their own MRI data? Wild!!
I can't wrap my head around the fact that shining a uv light into a container of resin doesn't cure all the resin in the container.
I guess its kind of like radiotherapy? It takes intersecting uv rays from several different angles to actually cure the resin.
Woah... That biomaterial application is really, really promising. Organ printing would be an actual whole other application for the space industry that could potentially be done profitably. Quite a remarkable potential addition to the handful of already viable manufacturing avenues.
Congratulations to them that they are involved in such a fascinating and potentially relevant technology.
Up the projector count to 3 to improve quality and production speed. From the bottom, side and 45° off from the top.
Probably work great for making lost cast mold rapid prototyping
Thank you for the CT scan example. It made it a lot easier to understand.
this is the most insane thing I have ever seen and it makes so much sense, resin printing is about to radically change at least in the next 10 years and calling this magic is NOT clickbait
“Hi, I’d like some of those 3D printed gummy bears please”
-Me, not too far into the future
I totally dig that young man’s vibe. That lab is so awesome.
Would calling this 4D printing be more appropriate, it seemingly surpasses 3D printing, and would make the technologies clearly distinguishable in speech without extra acronyms.
I was merely impressed until the end of the video. Open source!? Holy... 😲 This means formulations will be open source to!? This is beyond impressive, this is a game changer!
EXACTLY!
Very interesting!
I'll be sharing this with my university, this is sure to be interesting to at least more than one person there!
This is awesome!! Im waiting very very impatiently
Makes you wonder, given the current 3d printing machines we have rn, which methods and mechanisms of printing under what gravitational pressure would produce the most effective prints (integrity wise)
for people having trouble understanding it, it's actually really simple. it's just a projector projecting a 3d model that is rotating at the same rate that the resin is rotating. it's very clever and elegant.
H how
From all I understand the first thing the light touches is going to be the thing hardening first, so, like, the liquid right next to the wall will solidify first and quite evenly (because it is spinning)
How does
Like
How does depth information be transferred, via a single projector, with a single point of view of the object? Us humans and, a lot of animal for that matter needed both of our 2 eyes to extract depth info
god the guy is so award. This is why you get a promoter for your big projects.
Can it do hollow sections within the print like channels and arteries or is it only solid objects?
This is an interesting approach to having a process optimized for use in micro/zero G environments. It would seem that if you wanted to use this here on Earth, you would still need a support structure. I could see something like the part being constructed around a thin metal pin might be all you need to tweak the process.
The viscous resin they use prevents easy flow, even when the projector light is heating things up. The resin itself acts as a support structure because print times aren't long enough to heat the resin enough to make it flow.
This is not the absolutely weirdest method of supporting a print I have seen.
Rotate the projected image in stead of the vial and you get rid of the centripetal force.
According to my calculations the "cure through" dose needed would negatively impact the part accuracy... or if you tuned the absorptivity of the resin to get decent accuracy, you would be left with large radial conversion gradients in your parts... interesting chemical engineering problem 🤓
Just the outside layers?
I'm curious about what kind of resolution this can print down to. Like can it print small gears or 'build in place' mechanisms with break away supports... or is it only capable of printing solid objects?
Resolution would depend on two-ish factors - X-Y resolution of the projector being used and its contrast rate. The brighter and darker that the image being projected can be, the clearer the details along the projection axis of each slice can be. There are a bunch of tricks that can be done to up the resolution, for using collimating lenses so all the light striking the resin is parallel, to using some kind of laser optics on (what I assume) is a DLP reflector.
An even slightly powerful UV laser that could project a beam roughly the size of the projection element, routed through optics that first magnified the resulting image and then re-collimated the beam path so that all of the light hit the resin dead-on would make the features as sharp as is reasonably possible. At that point, it's really a matter of resin chemistry.
I lie, you can get sharper if you want to start playing with weird split-beam quantum effects and special polymerization chemistry that requires two photons to hit the polymerization molecule at the same time. But at that point you're talking about a process so delicate that you would need to do it in a chip fab's clean room to ensure results. Maybe someone needs resin thingies that can't be made any other way with super-duper fine details, but I doubt that they need it enough to invent it.
1:45 instead of rotating you can use 6 laser projectors to make the image?
How you solidifie the inside? This in Space is better because no need of suport.
Nice tech.
This mind blowing...🤯...and it is very reassuring to see that some of this generation are setting the right priorities.
this is amazing.
I might be way off but the only way i could see this to be possible is if you have a beam of light that gets converged to a focal point and in that focal point the energy density is high enough for it to solidify.
Later for the zero g. We can project supports. More importantly! We can increase or decrease UV intensity at a specific distance🤔from the projector
What a insane process of printing objects. I love it.
Open Sauce was an amazing time! So glad I got to have a booth, so many amazing creators!
I was not expecting space organs when i clicked this video. This is an awesome technique.
NO ONE expects space organs!
This is awesome and mind bending, they need to have this calibrated so good, and take into account scattering, reflection, refraction, energy absorbtion etc.to be able to polymerize only the intended volume. But I believe the surrounding polymer gets compromised and cannot be used a second time, therefore for the moment this will be quite a wasteful process.
Great interview! Calling it lithography obscures the fact that it uses "reverse tomography" which is the brilliant insight that makes this revolutionary technology possible. Thanks for including links. The bioprinting aspect is exciting when done in zero-G and I'm eager to see the experiments and their results.
I honestly want to call it "reverse 3D Picross".
Can the prints have internals or is it currently limited to solid/external structures only?
That's what I'd like to know as well!
This could quite possibly be the future of resin 3D printing.
this is so cool, i wonder if we could get some slow mo footage of the printing process in action, id love to watch in detail how the material forms!!!
What a nice guy! Really liked his explanations
The zero gravity printing reminds me of gigastructural manufactoriums in sci-fi, so awesome.
Wow, oh my goodness, I'm geeking out to I want space organs. I am absolutely going to make one of these printers
Game changing, it will be interesting to see if there is a way to print opaque resins. Also great its open source so everyone can contribute.
This team just made a money printer along with a 3D printer. Happy theyll get funded. Hope they can release it to mass production
This is a potentially revolutionary process, it could very well be the foundation for (and I use the term cautiously) a replicator type manufacturing process.
This tech is incredible, I cannot wait to research further.
I think this is how they treat cancer with radiation. To minimize the effect of radiation on the healthy cells, they move the radiation source around while directing it at the cancer so although healthy cells are being hit with radiation, it’s all concentrated on the cancer
This is pretty amazing. I can imagine there will be some limits to geometry, but the print speed is really impressive. This really fills the gap where layer resin printing is too slow and injection molding is too expensive.
This is amazing. And I love that they’re making it open source too
