TOM 3 Optical System Design, Tolerancing and Manufacturing
SwissVAMyKnife.jl: an open-source package for tomographic volumetric additive manufacturing
Laboratory of Applied Photonics Devices, École polytechnique fédérale de Lausanne, Lausanne, Switzerland
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 \SI{20}{\micro\meter}.
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.
