3D/4D Printing of Polyurethanes by Vat Photopolymerization

Jessica Mauriello, Romain Maury, Yohann Guillaneuf, Didier Gigmès

Abstract

Abstract Vat photopolymerization relies on the light‐induced polymerization of liquid photopolymer to produce the targeted structure. Among all the polymers prepared by vat photopolymerization, due to their numerous properties polyurethanes have recently gained great attention in the industrial and academic fields. In this review article, recent progress in printing techniques, resin compositions, and applications related to 3D/4D printing by vat photopolymerization of polyurethanes are highlighted.
