Photocurable resins for volumetric additive manufacturing

Abstract

Methods and materials for volumetric additive manufacturing, including computed axial lithography (“CAL”), using photosensitive resins comprising a photocurable resin prepolymer; a photoinitiator; and (optionally) a curing inhibitor. In various embodiments, such photosensitive polymers comprise (a) one or more monomer (or prepolymer) molecules, which form the backbone of the polymer network of the polymeric material and define its architecture; and (b) a photoinitiator that captures illumination energy and initiates polymerization.
