  • Patent number: 11141878
    Abstract: A method and a fugitive mold for producing a cast-metal part are provided. In some embodiments, the fugitive mold may be formed by three-dimensionally (3D) printing a preceramic resin in the shape of a fugitive mold; curing the preceramic resin to form a preceramic polymer, and pyrolyzing the fugitive mold to convert the preceramic polymer to a metastable ceramic material. The metastable ceramic material may include an amorphous silicon oxycarbide ceramic. A cast-metal part may be formed by filling the fugitive mold with a liquid metal or alloy, and allowing the liquid metal or alloy to solidify over a first length of time. The cast-metal part may then be retrieved by heating the fugitive mold at a temperature lower than the melting point of the cast-metal part for a second length of time longer than the first length of time to disintegrate the metastable ceramic material.
