The present disclosure provides a photopolymerizable composition. The photopolymerizable composition comprises at least one urethane component, at least one monofunctional reactive diluent, an initiator, and optionally an inhibitor. The present disclosure also provides an article comprising the reaction product of the photopolymerizable composition. Additionally, the present disclosure provides methods of making articles. The method includes (i) providing a photopolymerizable composition and (ii) selectively curing the photopolymerizable composition to form an article. The method optionally further comprises (iii) curing the unpolymerized urethane component and/or reactive diluent remaining after step (ii). Furthermore, a method is provided that includes receiving, by a manufacturing apparatus having one or more processors, a digital object, data contained in the digital object specifying an article; and based on the digital object, utilizing the manufacturing apparatus to generate an article through an additive manufacturing process. A system is also provided that includes a display that displays a 3D model of an article; and one or more processors that, in response to a user-selected 3D model, cause a 3D printer to form a physical object of the article . |
