The FUTURE of 3D Printing? Computed Axial Lithography!

Axial Lithography... so hot right now...

Hell yeah! Kudos to these folks for making things open source!

Really neat! The overprinting probably provides a lot of interesting use cases.

This dude's a really good presenter. He even has the textbook engineer nerd voice.

This guy was on it! Taylor rules!

WOW, the implementation of print time alon, for medical supplies is incredible. BUT THE ABILITY TO PRINTOVER OBJECTS?! Especially at that scale is INSANE, great work. Excited to see this get used for incredible things.

I love it when science is also open source. This is amazing stuff!

"links down below"... yes, I see lots of links, but none of them seem to be relevant to the video? Shouldn't there be a link to the open source project y'all were discussing?

These guys definitely had fun hanging out.

Automatic thumbs for using a Monty Python clip after someone says Python.

This is a great video and Taylor just seems like a great person. I can feel the enthusiasm from here and it is infectious. 👍

This is basically a CT scanner in reverse. A CT (computed tomography) works by having an Xray camera rapidly spin around an object taking hundreds of Xrays that a computer then reconstructs into a 3D scan of the object. This works in reverse, taking a 3D scan and splitting it into many still images that get projected like a video onto the object as it rotates. The high transparency of the resin means the light can pass through like an Xray and interact with the whole vial, but only cure when repeatedly exposed from multiple angles as the vial rotates.

So awesome. Thanks so much for sharing your expertise and advances. Can't wait to see what else you'll have to share in the future.

Fantastic work, BUT, what I don't get is how comes the photons passing through the resin to form the structure don't actually polymerise the path they pass through?! In fact they probably do but the intensity of the light is designed to be high where the structure is and lower on the way to it. This raises the question of how reusable the remaining resin which probably would contain semi-polymerised resin, which is unlike SLA is mostly reusable.. worth clarifying...

Taylor mae this a joy to watch. Passionate about what they're going there, and able to communicate it in a natural way.

Thank you Joel for your great coverage of such cool technology for our future! And thank you to all my fellow engineers making our tomorrow possible for the world to enjoy.

I've seen something like this about 20 years ago at NJIT. Instead of a projector they used multiple lasers around the object. Not sure what happened to it, though. The professor that showed me an example print was quite peeved that they were using it just to make models of molecules and not seeing the value of the creation.

That's really interesting. I have a doubt though. When we are rotating a container filled with liquid, the liquid may not rotate with same rate as the container. This effect will be lower for a liquid with high viscosity and less density, but it will always be present. Does this pose an issue in this technique? The solution could be simple, i.e. rotate it slowly or rotate the light source.

Cool to see a video of that. I visited UC Berkley 5 years ago and talked with Hossein Heidari (left one in your picture) about that. We also made a "Thinker" in a glass vile which I still have. Cool technology.

Wow!! Looking forward for this technology to improve!
