UV‐curable inorganic precursors enable direct 3D printing of SiOC ceramics

3D ceramic parts are of great interest for various applications including aerospace, defense, electronics, photonics, and biomedical. Yet, additive manufacturing ceramics is challenging due to their poor machinability. Herein, two approaches based on the chemical modification silicon resins obtain UV-curable preceramic precursors SiOC described. The dual functionality synthesized acting both as precursor photopolymerizable entity under UV light exploited. A set characterization techniques has allowed investigation mechanisms involved in synthesis inorganic according following approaches: (1) blend resin with photoactive monomers (2) a single source resin. correlation between nature properties derived analyzed. From technological point view, materials can be fabricated dense or crack-free porous customized objects low mass loss optimal surface quality.
