"The speed, geometry, and surface quality limitations of additive processes are linked to the reliance on material layering. We demonstrated concurrent printing of all points within a three-dimensional object by illuminating a rotating volume of photosensitive material with a dynamically evolving light pattern. We print features as small as 0.3 mm in engineering acrylate polymers, as well as printing soft structures with exceptionally smooth surfaces into a gelatin methacrylate hydrogel"

"Two limitations of additive manufacturing methods that arise from layer-based fabrication are slow speed and geometric constraints (which include poor surface quality). Both limitations are overcome in the work reported here, introducing a new volumetric additive fabrication paradigm that produces photopolymer structures with complex nonperiodic three-dimensional geometries on a time scale of seconds."

"Powder bed fusion would be excluded for now mainly because it would likely require way too much energy to be able to control it. Even if researchers were able to develop a volumetric powder bed fusion process for polymers (perhaps an evolution of EOS’s LaserProFusion), it would still take many years before even beginning to consider applying it to metals (although EOS’ CEO Adrian Keppler did tell us it would theoretically be possible at formnext)"

I'm 61 years old,... and now I'm officially living in the future I dreamed of as a kid! The first time I saw a 3D printer and CNC machines was a big deal... now we are hopefully headed toward creating fully realized, functional replacement parts for us aging humans... I could use some new parts!!
Dr. Aubrey deGrey seems to have quite a good angle of attack with regards to the Problem of aging. Check him out, if you're interested in our progress on that. :)
Have you heard of NAD+ pill. It's used for de aging process. It's still in development and hasn't been perfected but I read that it help cells to regenerate and also helps us stay younger longer. I hope this isnt farce and actually works cause I haven't tried it yet.
I'm with on that my friend!
Hope you many more years to see more sir
where is my flying car damnit XD
I think it's *AMAZING* if it actually works as intended. That being said I suspect there are a lot more problems to overcome than this video would have you believe and the implication that the material will be cheap is something SLA and CLIP both claimed but it turns out they were talking about relative to the most expensive 3D technologies there are like SLS and not compared to FDM which is what most people think of. This kind of reminds me of the CLIP 3D printer where the demo was amazing with crazy print times and watching the items just materialize before your eyes over a few minutes and then when it came out it was hundreds of thousands of dollars and the material was stupid expensive.
Here are a few problems I anticipate...
1) The material will not only be expensive but also have a short shelf life due to its photoreactive properties and oxygenation
2) The photoreactive nature of the material will make it break down faster in sunlight vs. FDM materials like PLA, PETG, Nylon, etc
3) You can only print in this one material so you'll have to make casts from the prints to produce parts that are durable and functional for your specific needs
4) The bulb in a DLP projector progressively gets dimmer (unless it's Laser) meaning you won't get too many prints before needing expensive bulb replacements
5) Particulate that forms in the vat will need to be removed meticulously to prevent print quality degradation from light deflection
6) Resolution at larger scales is going to be hard limited to the DLP projectors resolution, will look great on tiny prints but garbage on large prints
7) I don't see build volume on this improving much because even if it did the cost of material to fill the vat for any size print would be insane and more waste when it goes bad
8) Just like with SLA I'm sure you need to post-process the prints with UV curing to further solidify the material to its full hardness (this adds time which negates its speed)
... So, like I said, if it works and they solve all these problems you won't be able to keep these printers on the shelves but I suspect this will end up being used only for printing very small things and the cost will be high so it wouldn't be used to manufacture final shipping products but rather prototypes. But, as I said, if it works I'll be the first to buy one if it's cost effective or even on par with Form 2 for that matter 👍
I'm glad to find someone else who is thinking a little more about the many challenges of this form of printing. Two more potential huge limitations to add to your list: 1) precise timing between the speed of the rotated image and jar of rotating material. 2) Rotating fluid is subject to increased mixing (entropy). Keeping the newly polymerized particles at the same eccentricity from the center, in a rotating medium seems extremely imprecise. Compare the smeared Thinker in the video to a high quality print from nearly any commercially available FDM printer.
The big selling point is that it doesn't need scaffolds, but if you're trying to print in a discrete location in space in a swirling bath of material YOUR SOLIDIFIED POLYMER is going to move! To prevent this, one could add scaffolding. At which point, you may as well use an SLA printer.
What a wonderfully thought out and constructive comment. Never even been near a 3d printer I don't have nearly the insight you do but I can still appreciate all of this.
@@roberthermosillo5727 the higher the viscosity, the better the support, which means the solid will not move much due to rotation.
I believe penetration depth of the light is still a big problem, that's why you only see small objects printed.
We are now one step closer to having Star Trek replicators.
And also printing Hot Russian Babes like The 5th Element! 😈
@@andreysimonov1667 She wasn't Russian, but yeah, okay. I'm on board with that.
Make more great videos bud
Replication in theory releases lots of heat that would destroy whatever it's being replicated , Star Trek one doesn't so it isn't based on sound science.
Actually Arthur C Clarke invented the concept of replicators, Star Trek stole his idea ;)
YUGI: Summon this monster using POLYMERIZATION!! 4:08
You tried buddy
Frog Prince I did ! Haha XD
1. Resin starts after few objects to increase in viscosity.
2. Mechanical proterty of cured resin, temp curing after presume
3. Price of tech and material
4. Chemical property, tech prop.
( gluing, velding, adherence of finish, metalization)
I think that the potential of the clip 3d printer is still greater with the fact that that printer can print in very tiny scale with incredible precision, when it will improve even further it will become truly game changing.
Now i just need a friend who has one i can use...
Dont get to excited, this is still in its infancy stage, as well failing to meet certain requirments funding for this has been cut to more than 1/2.
Although there was a good deal of excitment for this in the beggining.
it has taken a back seat to more ground breaking 3D tech that will be revealed mid 2020.
The US Navy used 3D printing, in their subs, in the 1980's. It cost $40M! Why spend that much? Because if something broke on a mission, they needed to fabricate it while underwater. The 3D printer could create metal objects like tools and reactor parts.
Imagine what they are using today..........
Bob Bobby companies like space x use metal 3d printing to make custom unmachinable parts for their rocket boosters! Crazy stuff :)
Is a first step about molecular reconstruction. Congrats!!! 👏🏻👏🏻👏🏻👍🏻
I don't know… It's an improvement, sure. But it depends on a special type of transparent resin. It's a good idea, which will have its uses. But it would be even better if they can get it to work with a wider range of materials.
game changer 😒😒😒
Given how many polymers and organic materials react at certain wavelengths, this can be quite easily expanded upon. Using a quencher like an abundance/removal of oxygen is already done in the 3d printer world let alone a lot of other production methods. I bet you now that in ten years we will have discovered at least 5 other reactive polymer groups and 3 quenching methods that can work with photon hardening. Adjust the structural part of the polymer to a different length, add special side groups or extra interpolymer bonds and you will have a wide range of tensile strengths, elasticity and other properties to choose from.
Another way would be to suspend photoreactive enzymes in the resin that will catalyze reactions when hit with photons. A competitive inhibitor could work as a quencher, and you can polymerize everything we have enzymes for.
This invention will ease my line of work considerably and I cannot to get my hands on one of these bad boys
Finally, I predict that once we will have active areas that polymerize on different wavelengths, we will be able to make products that have different properties in the same products by activating these bonds placed at different sites on the polymer in different areas of the product. Spongy in the centre, hard on the outside etc etc etc.
What a time to work in chemical innovation
You don't need it to print using different material. You can use the first object to make a mold container that you would use as a matrix for creating objects of different materials. It is not even important if this material is organic or not, because you can use this for fast prototyping and then create a shape container for other materials.
Dennis Klomp Hmm… Okay, cool! Seems like there are plenty more potential uses for this.
finally an innovation that actually matters....as far as printers go.
For those interested, I'm pretty sure they are using Radon transform to translate 3D shapes to 2D projections. Check it out it's pretty cool!
IMHO, better to rotate the light source around the object. There is centrifugal force on the object on the current prototype. Even by a small amount will still be a huge factor in improving accuracy.
They say it sets all at once, although I'm pretty certain that the outer most layers cure first. I wonder if the inner most core of the component is partially unset resin in some conditions?
I love this technique, can't wait to work with it. I have worked with all and i am most excited by this one.
Great, now we can start from scratch the months long learning curve on 3d printing. All the while convincing ourselves we need to build something ourselves that could of just bought that is 5000% cheaper and took 94 hours less time.
That's exciting 😁 I've often thought of using a holographic image to solidify resin lol
How does this relate to how a holographic image is stored/created? Is there any way to exploit holographic properties to speed this up? Or perhaps do this without spinning? Like using an LED sheet/ring filter around the vat and doing all sides at once?
Beam me up, Scotty! (Scotty uses laser to kill the crew members on the planet surface and spawn clones in the transporter, Scotty is the captain now)
i wouldn't start making synthetically produced cats or anything you need the other half of the teleporter tech for the ease of doing its job.
What sort of polymer is the product? And whats the monomer called? Genius stuff
What a time to be alive. I cant wait until they can print around someones amputated limb to make a perfect fit.
The company I work at is Magority AM and I would love to see this printer on our shop floor
I can see that this would be far more limited in the shapes in can print compared to "traditional" 3D printing. Concave shapes or any complex shape where some details can be obscured from the laser by other sections of the shape will be very problematic.
This was superb...
Humanity already knew the Fabricate spell. Now we've learned Creation. Give it a few more decades and maybe we'll figure out Wish.
I'm glad my childhood YuGiOh Polymerization is being used in science.
What about this principle to Target and destroy cancer or any unwanted cells and Tumors using frequencies?
Any possible pigmentation is out of the question.
Other than the 'edge quality' I don't see the HUGE STEP described.
How is this so much better than, say, a 3D printer that prints metal rocket engines ready to use?
it's not. lol. its pretty fast, and it has places where it works better than another type, but it has drawbacks tied to it. It's roughly equal to anything else, if you're only looking at the end product.
When;
1. The process can be used with metals. Game Changer.
2. Both in the same time.
More so.
3. Food.
Seems to require a transparent resin, so metal would be difficult, Food is probably do-able, so long as your ok with a translucent burger
@@UNSCPILOT
Yes..
Although..
1. Hardening could be done in a medium that becomes opaque..
Or a metal containing Emulsifier..
Where the heated stuff attracts the Metal containing blubbs. Where they will form..
Remember it's not creating something out of nothing. It's changing the state of the gel. In order to make food you'd have to use some sort of edible material, and why sculpt something from edible material when you could just eat the edible material?

More fun that way.
I just want my Star Fleet issued replicator already!
Hopefully the precision gets much better, otherwise there is very limited usage for this technology.
You were an awesome speaker. I want to see you on cbs news someday. Oh yes. Great technology.
Well, thanks to new developments of modern science, I'll be finally able to print a life size sex doll at home!!!
How long before it reaches the average consumer?
AWESOME ... Big THANKS for great video ... 👏😎
Great! IF these printers will be affordable and resins will be with all necessary kinds and qualities (features) then it will become the era of cheap tooth implants (not all the implant parts, it's just to simplify), custom prosthetics and etc... Who knows but maybe this will be the new step to growing human/animal organs.

OMG ! You too? What is it with 10 mill ?!
This is HUGE, and the tech is still in it's infancy. It's going to be amazing what CAL can do in the next 12-18 months.
It's neat for sure, but not quite what it's described as. The rotating method is a reversal of space carving, and simply uses more angles than stereolithography - which STL is named after. There is still a resolution limit from the projector, although dynamic because the edges vary in distance from it. Rotation speed must be kept low so the gel does not shift much, and since it projects through it all the gel is used up for each print. As usual real world approaches are rife with compromise.
this tech has been around since the 90's
I want to see some makers in the community put together their own. None of the actual tech is unique, it's an off the shelf DLP projector with a lens. The rest of the materials look like they could be bought or readily made.
@@0LoneTech Using up all the gel could be made a little easier by varying the size of the container to match the size of the printed object and filling the flask to the bare minimum amount to cover the object.
Also I think the resolution limit is actually a function of the projector resolution and the degrees rotated per frame. So it might actually be quite good.
It seems to me that this isn’t technically 3D printing, but more of an emerging technique that will possibly rival and/or supplement 3D printing. The very fact that they didn’t make or modify a printer fascinates me. They just took two ideas, SLA printing and STL, which has been used for years to make those cool blocks of glass with 3D sculptures etched inside with lasers and tweaked and combined them. That’s so clever!
Whoa it's like 3D printing hard holograms in seconds, using light!? That's incredible and with that resin they're using kinda looks like they're printing stuff out of thin air. Pretty freaking amazing!
I was working on this back in 2004, 15 years ago. I am glad they pushed the technology to the point where it worked! Amazing

Extremely important step in the evolution of 3d printers. May be in 5 years we may be able to order these type of printers.
'Order' Hell the fact you said, 'five years' when traditionally we'd have wait around ten to twenty shows the advanced state we are living in, maybe in five years we could just simply 'print' these printers from our home printers.

I guess the obvious limitation is non-transparent or coloured objects, or what?
One would think so for now. Shouldn't be long till they invent a resin that cures opaque. Till then: hey, primer still works.
@@drumkommandr9779 I think it would be easy to "drain" the first 3D_making resin (once you have the actual object made), then fill it up with another resin that reacts with the light making an an specific color on selected points of the sculpture´s surface [then you drain it again and refill it with a different one for another color...] until you get the entire surface "painted" using the same laser [that is likely to be the most expensive part of the machine].
I assume you can do the same thing we do with current methods - paint the model after it prints.
@@GrimIkatsui sure, but then you can also CARVE it from wood... the idea it to FULLY AUTOMATIZE it to make them ON MASS (or on demand), no skill, no personal time or effort required -> THAT is a revolution!
@@adolfodef erm that would be a very long term end goal (and one some companies won't keenly agree on), for now this is best for fast prototyping and some DIY just like regular 3d printers.
Im an experienced 3d printer, and although this looks interesting, there are several serious problems with this tech. Resolution is terrible, you cant print accurate parts. The resin is toxic , messy, expensive and final curing time negates the advantage of the quick print time. With a lot of R&D this might get better.
Atleast it’s a step right in the right direction.
Imagine similar principles with different mediums, one could create all manner of resulting qualities, nutrition, or otherwise.
unless you're into manufacturing parts for prototypes, i do not see why the average person would invest in a 3d printer. I haven't even used a normal printer in years.
The execs at IBM felt the same way about the "personal computer".
@@bob_frazier you can't compare personal computers to 3d printers. A 3d printer is useless without a PC and is much more of a niche market.
It's for makers and tinkerers
@@jerrymiao7605 I agree. I personally would not invest in one now because they are too expensive, but i do think this technology is great. If i were an engineer / architect or really into gundam i would definety get one.
I'm confident that one day this tech will be ubiquitous. When you can just go and print a tool or other object you need, using a blueprint you downloaded from the internet, instead of going to the store to buy it, it will be a huge time saver and convenience. People of the future will wonder how we ever put up with having to go get something we didn't have. Of course, there will be limits, but there would still be a huge application even for simple objects. More so if the gel is reusable so you can just recycle it when you're done.
"Tea, Earl Grey, hot."
The screwdriver handle looked like complete garbage. Also, everything looks wet and the detail level sucks, so I have my doubts about it having ANY strength. You can hope all you want that a "new technology" just has a few issues that need to be improved, but there is NEVER any way to know anything can be improved, so whatever you see, is all you can count on. Planting the ideas at 4:22 is nothing more than trying to get people to share this video. The inventors of the device never made such claims, they only made a proof of concept that you can make a Jello into vague shapes. If you want to use it for something like a leg, made out of jello, you're a fool. When asked about bio-compatibility, the reply was just "it's something to learn about", which means, basically nothing. Again, what you see in the video, is all this is. Nobody made a smartphone support stand out of jello, which could be small and would show it's physical strength. Be aware that in the video, never once did anyone touch the jello. Did I mention it's Jello? Just saying...
Also, what about hollow shapes? I'm having a hard time seeing how this can be achieved apart from multiple projectors but even then...
To add to what I said, I'm not saying I am against new technology and achievements, I just don't like when is talked about in a way that a casual listener/reader will get the impression that it's something better than it really is. To be fair, it's what "the news" is basically trademarked for, making things sound way better or way worse than they really are, which can cause people to make bad decisions, which can impact people financially or their health. People may see this video and invest money in it, not realizing the story was embellished, because maybe they are having a stressful time or tired or just wanting to believe what is said is 100% fact.
Can't wait to see commercially this could change 3d printing forever.
What's the resolution?
I assume in a real application those bubbles in the liquid resin would be removed right?
Well realistically the resolution would be limited by the purity of everything and the dlp resolution. The bubbles are probably removed by vacuum
Just look at the airplane it formed... Resolution is out of the question for now.
@@linuspauly2380, I'm not sure what that mean (I agree about using the vacuum to remove the bubbles) but I think you're referring to the gel. As long as its diffraction is accurately known it can be corrected for so I don't think the gel is the major limiting factor here (think of ground-based telescopes correcting for the distortion of earths atmosphere).
@@seiyachan That was what made me ask the question. I think the true resolution limit will be defined by the wavelength of the light, but practically the focusing optics used will be the real world limit. The examples shown in the video were made with a off-the-shelf digital projector, which will have very poor optics. I used to work in R&D Optronics (only as a technician) so I was hoping a techie might reply for a chat.
Bad Monkey i don't think the resolution has anything to do with the wavelength. cause the principle was something like projecting images of the object from different angles (instead of slices of cross section images at vertical layers), they will somewhat overlap at various extend at different images at different angles, which inturn solidify some addtional resin than what you would like.
I hope this could work across different materials someday, maybe using electric fields instead of light.
You could use DUMB microbots (spherical one-use batteries with a simple light sensor that makes them "magnetic" for a brief time), so you can use selective magnetic fields to control their position to BLOCK/reflect the laser [creating a "high density point"], so the resin could coalesce around/next/away from them from the "inside" of the object as it is made.
-> This allows for the use of multiple lasers shooting from all angles at the same time.
isn't visible light a small part of the electromagnetic spectrum? or ju really mean fields theory where fields are superior than particles i.e photons?
@@adolfodef i'm sure people hu envisioned this first thought of that already. then they were shot in the head because of their stupid suggestions.
@@kevintorres7045 not in the same context, no. it is fundamentally, but the actual usage is way different. you can have electricity and magnetism without light, light without either, and so on. It's all just energy and how you're actually applying it. like welding vs casting. both can make the same part.
You don't need it to print using different material. You can use the first object to make a mold container that you would use as a matrix for creating objects of different materials. It is not even important if this material is organic or not, because you can use this for fast prototyping and then create a shape container for other materials.

cool story bro
This seems like it is not much better than the techniques we use currently with molds. This will definitely have niche applications, but I don't think it will replace current methods on a large scale.
If engineers can figure out a way to get other materials into the mix and still have it polymerise, that would be useful.
It’s not really for mad production it will make prototyping better and faster
FDM printers replace current methods today, this will be adopted instantly it becomes available.
Although its a great idea and it does seem way faster, its going to need to get considerably better in terms of quality. I would rather a print take a few hours and look great (sometimes flawless with SLA and DLP) then have an unrecognizable model that was printed in 5 - 10 minutes that looks like a blob of partially cured resin...
Potential is definitely there but its clearly in its infancy.

Every dollar spent printing prosthetic limbs with this, is a dollar not spent printing genetically engineered catgirls for domestic ownership.
Money well spent
that is really specific to be an actual thought.

Damn, for only €3800? I am already requesting a sample.
Resolution looks pathetic for now but at least the time issue of FDM printing has been solved using this method!
Maybe not... As they said in this video, you need a very special kind of resin to do this. 3D printers are useful because they can print in an extremely wide variety of materials. This is what makes the difference between highly valuable manufacturing 3D printers & the plastic printing toys most people have at home.
Edit: because this is the internet -- when I say "most people" I'm talking about "most people who own 3D printers" obviously.
The way funding works, they need proofs of concepts to get more. if investors were smart enough or had the time enough to learn, they wouldn't need a proof of concept. But because of that they made the first proof of concept to get more funding for the second, which rotates further proving the process, now they will try to get more funding to develop this method further. multiple high def projectors from multiple sides and a better resin is likely all that is needed. I bet a resin that turns opaque when hardened, combined with maybe creating the object minus a few mm's first would prevent some of the light from going too far through and allow them to use greater intensity to harder just one side at a time as they finish it to get the details done.
Def room for improvement.
They're doing this with an off the shelf projector. I imagine one of the next steps is building a projector specifically for this task that can project in greater clarity.
This is what I imagined when I first heard of 3D printers
I think technologies are starting to hit that exponential growth point :D
Yeah but there's too much advancements were someone can be on to something revolutionary but hit a road block and what they need may be out there already discovered but no one knows everthing released in science only ai can do shit like that but I don't know how I feel about that all powerfull computer beings
I hope we make some more advancements in gene editing we have the tools we know how to do it but we don't know what does what. Definitely dangerous stuff but we got laws that probaly won't workout in long run but we're safe for now. Definitely shouldn't be done on humans only on shit like plants in a controlled environment like some kinda cdc containment center type thing. Their doing the studys but the field is very small there is so many advancements that are easily available through trial and error we just need more funding adding that gene editing knowledge to our compendium than we can find newly discovered gene functions and compare them among species which may allow us to know how to safely and ethicaly alter human genes with precision
We have been in a period of exponential growth, in terms of technology, since industrial revolution.
Yes and now more than at any time in the history of humanity we need to start treading with caution as it's said we are barreling headlong towards the Great Filter and that our own technology could pose a true existential threat to us now. I'm all for massive advancement but collectively as a species we need to be on point so we can survive our technological adolescence and survive to technological maturity, at which point we should be able to handle most any existential threats that may come our way.
cool concept but you can tell that the resolution of the model is pretty terrible. Not sure how much they can improve this, but it will be interesting to see where this goes.
Yeah, I was wondering if anyone else noticed this.
Current 3D printers using PLA or Polycarbonate can achieve precision as sharp as ~20 microns which is insanely precise.
Most printers are closer to ~50-200 microns but there are some very precise printers out there.
I’m designing my own “Infinite Precision” motor, I don’t know what to call it but it’s totally insane, you can’t even begin to imagine it’s design lol. But it will allow me to build a 3D printer that should be less than 1K and be better than the million dollar printers, and I have a “new” style of printing also, well it’s a revolutionary mix of different types in one printer being used at the same time
Awesome. Link please?
I don’t have it on a site yet, I’m just recently getting started.
Make a video about it
of course, it's a great project. Innovating things with just a flash of light is mindblowing.
How about printing hollow shaped objects?!...🤔

Why the process is called lithography? It doesn't include stone nor the general chemical procedures of lithography... is like calling a boiled egg a "crystallized" egg.
Lithography is another term for printing, and this is about 3D printing...
New technology? More a step forward from work that began in the 1960s.
