A photopolymer is a polymer that changes its properties when exposed to light, often in the ultraviolet frequency of the electromagnetic spectrum. These polymers are used as image carriers in flexographic printing, as components of fillings for dentistry, as ADA-compliant architectural signage, and in rapid prototyping for the stereolithography and 3D printing processes. The basic material is soft and light sensitive, and when produced will undergo a selective exposure, development and curing process. Some commercial manufacturers for photopolymer include DuPont Cyrel, Flint Nyloflex, MacDermid, Asahi Photoproducts, Eastman-Kodak, Novacryl, Elaslon, and Soleflex Exaprint.
