We introduce an optimization framework for ray and wave optical tomographic volumetric additive manufacturing (TVAM). In TVAM, tomographic patterns are projected with a light modulator onto a photocurable resin from different angular directions. Once an energy dose threshold is crossed, the resin starts polymerizing. Current approaches assume a ray optical model for light propagation, using the Radon transform as backbone, which breaks down for small features in the region of 20 μm. In this work we describe how a wave optical framework allows to optically print smaller feature sizes. The optimization framework is written in the programming language Julia and allows for high-performance optimization of ray or wave optical based patterns for volumetric additive manufacturing.
