Novel printing geometries for tomographic volumetric additive manufacturing
28 January 2025 • 2:40 PM - 3:00 PM PST | Moscone South, Room 155 (Upper Mezz)
Abstract
In this talk we present improvements and novel printing results obtained with our differentiable ray optical framework (called Dr. TVAM) for Tomographic Volumetric Additive Manufacturing (TVAM).
In TVAM different 2D patterns are illuminated on a rotating vial containing a photosensitive resin. Dr. TVAM produces patterns which outperform printing results in scattering media by simulating the ray optical propagation physically.
Also, for the first time we print in a square vial without index matching bath. And for striation mitigation we print in a tilted TVAM geometry where the light illumination is not perpendicular to the rotation axis.

Felix Wechsler is a PhD student at the École polytechnique fédérale de Lausanne (EPFL) in the Laboratory of Applied Photonics Devices (LAPD) led by Christophe Moser.
Prior to joining EPFL, he obtained his bachelor's degrees in physics and computer science at the Technical University of Munich. He holds a master's degree in Photonics from the Friedrich Schiller University of Jena.
His master's thesis about the Kaleidomicroscope, a multi-view single shot microscope, was awarded the Applied Photonics Award. Further, Felix is a gold and silver medal winner at the International Young Physicists' Tournament.
His current work is focused round computational optics such as 3D printing, imaging and algorithms implemented in Julia.
