Abstract
Some variations provide a preceramic resin precursor formulation comprising: first molecules comprising at least one Si—N bond and/or at least one Si—C bond; and second molecules of the formula R—N═C═O or R—N═C═S, wherein Ris a UV-active functional group. In some embodiments, Ris selected from acrylate, methacrylate, vinyl ether, epoxide, oxetane, thiol, or a combination thereof. The first and second molecules are reacted with an isocyanate or isothiocyanate to form third molecules, providing a preceramic radiation-curable resin composition. The resin composition contains at least one Si—N bond and/or at least one Si—C bond in the main chain of the third molecules. Side chains of the third molecules may be selected from hydrogen, unsubstituted or substituted hydrocarbon groups, halides, esters, amines, hydroxyl, or cyano. The resin composition may be 3D printed and thermally treated to generate a ceramic material.
