Abstract
A vat resin for three-dimensional stereolithography printing of a thiourethane polymer part comprising a liquid mixture including a first type of monomer, a second type of monomer, a photolatent base decomposable upon exposure to a light to form a non-nucleophillic base catalyst having a pKa greater than 7, an anionic step-growth polymerization reaction inhibitor having an acidic group configured to form an acid-base pair with the non-nucleophillic base and a light absorber having an absorbance in the liquid mixture that is greater than an absorbance of the photolatent base at a wavelength of the light used for the exposure. Methods of preparing the vat resin and three-dimensional stereolithography printing a thiourethane polymer part using the vat resin are also disclosed.
