A method of three-dimensional stereolithography printing a thiourethane polymer part using the vat resin. Adding a resin to a vat of a three-dimensional stereolithography printer, the resin a liquid mixture including: a first type of monomer including two or more thiol functional groups, a second type of monomer including two or more isocyanate functional groups, a photolatent base, an anionic step-growth polymerization reaction inhibitor and a light absorber.
