摘要： Aspects of the disclosure are directed to treating a substrate, the substrate including at least one of a refractory metal or a ceramic material, and depositing a media onto the treated substrate to generate a casting core. Embodiments include a fixture, a substrate located on the fixture, the substrate including at least one of a refractory metal or a ceramic material, and a delivery head that deposits media onto the substrate to generate a casting core. Aspects are directed to a core configured for casting a component, the core comprising: a substrate that includes at least one of a refractory metal or a ceramic material, and media deposited on the substrate, the media having a dimension within a range of between 0.5 and 100 micrometers.

摘要： 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.
