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