Abstract
Volumetric additive manufacturing (VAM) via tomographic projection is an emerging platform for ultra-rapid 3D printing. By projecting all layers in parallel, print times orders of magnitude faster than standard polymer 3D printing can be easily achieved, without the need for support scaffolds. Despite these advantages, print results are in certain cases inferior to commercial vat polymerization due to the infancy of the technique. In this talk, we will outline recent progress made at the National Research Council of Canada to extend the capabilities of VAM and address inherent challenges in VAM. Topics covered will include the role of depletion and polymerization kinetics on print quality and novel resins for larger, faster, and functional prints.
