Summary: | Methods for forming a coated digitally manufactured part include forming an article by a digital manufacturing method; coating a surface of the article with a reactive silicon-containing precursor polymer; and treating the polymer to form a silica-containing coating, thereby forming the coated digitally manufactured part. An article includes a digitally manufactured part having surface striations; and a coating encapsulating the digitally manufactured part and comprising silica. An article includes a digitally manufactured part (i) formed by selective lase sintering, (ii) comprising a surface defined by coalesced particles, and (iii) having a surface roughness Ra of at least 0.1 microns; and a coating encapsulating the part and comprising silica. A composition comprising polysilazane is described. |
