An inverse rendering framework for tomographic volumetric additive manufacturing

This presentation about Tomographic Volumetric Additive Manufacturing (TVAM) shows that advances in the computer graphics literature can be leveraged to build a more general optimization framework for TVAM pattern generation. We show that obtaining suitable projection patterns can be formulated as an inverse light transport problem. We present Dr.TVAM, a new open-source framework that implements a physically-based differentiable renderer suited to TVAM, producing high-quality patterns. This approach can account for various printing process effects like refraction and scattering, and outperforms prior methods.
