Abstract: The present disclosure provides a method of making a non-oxide ceramic part. The method includes obtaining a photopolymerizable slurry; selectively curing the photopolymerizable slurry to obtain a gelled article; drying the gelled article to form an aerogel article or a xerogel article; heat treating the aerogel article or the xerogel article to form a porous ceramic article; and sintering the porous ceramic article to obtain a sintered ceramic article. The photopolymerizable slurry includes non-oxide ceramic particles; at least one radiation curable monomer; a solvent; a photoinitiator; an inhibitor; and at least one sintering aid. Further, aerogels, xerogels, porous ceramic articles, and non-oxide ceramic articles are provided. In addition, 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.
