摘要： Provided is a method for forming a ceramic article, including disposing a slurry in a mold, wherein the slurry includes a ceramic powder and a photoctivable pre-polymer; and forming a green ceramic article wherein forming includes exposing the slurry to radiant energy, such as ultraviolet radiation, wherein the radiant energy catalyzes polymerization of the prepolymer. In another aspect, provided is method for forming an article, including disposing a slurry in a mold, wherein the slurry includes a photoactivable pre-polymer and a powder and the powder includes a ceramic powder, a metal powder, or both; and exposing the slurry to ultraviolet radiation wherein the ultraviolet radiation catalyzes polymerization of the pre-polymer.

摘要： A method of making an object using mold casting, comprising the steps of applying a slip mixture into a mold fabricated by 3D printing or additive manufacturing technique, and firing the mold containing the slip mixture. A composition of a slip mixture for use with a mold fabricated by 3D printing or additive manufacturing technique, the composition comprising calcium aluminate, from 10% to 60% by weight, and a filler. Such method and composition can provide efficient and economically viable ways of fabricating objects having complex shapes and high density.
