摘要： A composition for preparing a ceramic product by stereolithography, comprising a mixture of a first ceramic material and a second materials comprising a photopolymerizable resin, a photoinitiator, and a dispersant. A ceramic product comprising a first layer formed from the composition, polymerized by UV exposure; a second layer formed from the composition and deposited onto the polymerized first layer, polymerized by UV exposure; and one or more subsequent layers, each formed and polymerized in a manner consistent with the first and second layers, arranged according to a preset pattern of the ceramic product. The composition comprises
the first ceramic material 3% to 28% by volume;
the photopolymerizable resin 70% to 95% by volume;
the photoinitiator 3% to 28% by volume,
the dispersant 10% to 20% by volume.
