Novel printing geometries for tomographic volumetric additive manufacturing

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.
