Abstract: A photo-curable liquid composition for additive manufacturing of silicon-containing carbide ceramic includes a polymethylvinylsilane (PMVS) resin that has photo-reactivity over a first photo-wavelength absorption range and a photo-initiator additive mixed with the PMVS resin. The photo-initiator additive has photo-reactivity over a second photo-wavelength absorption range that has an overlapping wavelength range with the first photo-wavelength absorption range. The PMVS and the photo-initiator additive are reactive to polymerize upon exposure to radiation having a wavelength in the overlapping wavelength range.
