This sounds like the technique shown by 3D Printing Nerd on YouTube: <a href="https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=oHPrnYMdLow" rel="nofollow">https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=oHPrnYMdLow</a> There they called it computed axial lithography.

You need a powerful light source such as a LED laser or a high power LED. Also the setup is not super trivial. To set up for non optics people.

Amazing stuff. I wonder what hardware you need to try it out.

So, it&#x27;s software for driving super-fast resin printers that work similar to beam radiation therapy (but with lasers and resin). Very cool.

Clicking the first image on the Github page takes you to a paper with a very good abstract <a href="https:&#x2F;&#x2F;rgl.epfl.ch&#x2F;publications&#x2F;Nicolet2024Inverse" rel="nofollow">https:&#x2F;&#x2F;rgl.epfl.ch&#x2F;publications&#x2F;Nicolet2024Inverse</a>&gt; Tomographic Volumetric Additive Manufacturing (TVAM) is an emerging 3D printing technology that can create complex objects in under a minute. The key idea is to project intense light patterns onto a rotating vial of photo-sensitive resin, causing polymerization where the cumulative dose of these patterns reaches the polymerization threshold. We formulate the pattern calculation as an inverse light transport problem and solve it via physically based differentiable rendering. In doing so, we address long-standing limitations of prior work by accurately modeling and correcting for scattering in composite resins, printing in non-symmetric vials, and supporting unusual printing geometries. We also introduce an improved discretization scheme that exploits the ray tracing operation to mitigate resolution-related artifacts in prints. We demonstrate the benefits of our method in real-world experiments, where our computed patterns produce prints with an improved fidelity.

There’s not much detail on this GitHub page. Is there an explanation for a regular person that isn’t deeply familiar with additive manufacturing? Is this software to be used to control a 3D printer? Or something else?

We published this work at SIGGRAPH ASIA 2024.Based on Mitsuba 3 and Dr. JIT we provide our software Dr. TVAM to optimize patterns for TVAM. 
TVAM allows to print centi-meter scale objects within seconds.
