An inverse rendering framework for tomographic volumetric additive manufacturing

2025

Abstract

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.

Computer science

Computer science is the study of computation, information, and automation. Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software). Though more often considered an academic discipline, computer science is closely related to computer programming. Algorithms and data structures are central to computer science.

Printing

Printing is a process for mass reproducing text and images using a master form or template. The earliest non-paper products involving printing include cylinder seals and objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of printing as applied to paper was woodblock printing, which appeared in China before 220 AD for cloth printing. However, it would not be applied to paper until the seventh century.

Printing press

A printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth), thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper, or other medium was brushed or rubbed repeatedly to achieve the transfer of ink and accelerated the process. Typically used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium.
