Manufacturing of metallic components via computed axial lithography and hydrogel infusion additive manufacturing

Computed Axial Lithography (CAL) is a 3D additive manufacturing process that is able to form all points within a geometry simultaneously by delivering a light dose to a photopolymer via tomographic reconstruction. CAL can avoid hydrodynamic rate limitations, allowing for higher-viscosity precursors, and fast manufacturing speeds. Hydrogel Infusion Additive Manufacturing (HIAM) is a recent additive manufacturing process that allows for the production of metallic parts but has only been demonstrated with traditional layer-by-layer additive manufacturing. This research demonstrates a modified HIAM process utilizing CAL, in which a higher-viscosity precursor material with additives is used.
