Abstract

3D printing has revolutionized the manufacturing of volumetric components and structures for use in various fields. Owing to the advent of photocurable resins, several fully volumetric light-based techniques have been recently developed to push further the limitations of 3D printing. However, these new approaches only work with relatively transparent resins so that the light is not impacted along its propagation through the material. Herein, we present a method to address this problem and print in scattering materials. It consists of characterizing how light is distorted by the curable resin and then applying a digital correction to the light patterns to counteract the effect of scattering. Using a tomographic volumetric printer, we experimentally demonstrate the importance of taking light scattering into account when computing the projected patterns and show that our applied correction significantly improves printability.
