Dense sintered parts of ceramic and/or metallic materials are formed using stereo photolithography. An initial flowable mixture of sinterable inorganic particles, photocurable monomer, photoinitiator and dispersant is flowed over a substrate and cured in a selective pattern. Subsequent layers of the mixture are flowed over the substrate and cured to build a three dimensional body. The body is then fired to produce a dense sintered part. Parts having in excess of 95% of theoretical density can be produced. |
