Wave optical model for tomographic volumetric additive manufacturing

Christophe Moser, Jorge Andres Madrid Wolff, Carlo Gigli, Felix Wechsler

Tomographic Volumetric Additive Manufacturing (TVAM) allows printing of mesoscopic objects within seconds or minutes. In TVAM, tomographic patterns are illuminated onto a rotating glass vial which contains a photosensitive resin. Current pattern optimizati ...

Inverse Rendering for Tomographic Volumetric Additive Manufacturing

Christophe Moser, Wenzel Alban Jakob, Jorge Andres Madrid Wolff, Felix Wechsler, Baptiste Alexandre Marie Philippe Claude Nicolet

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 polymeriz ...

SwissVAMyKnife.jl: an open-source package for tomographic volumetric additive manufacturing

Christophe Moser, Jorge Andres Madrid Wolff, Carlo Gigli, Felix Wechsler

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 en ...
