Abstract: A molding apparatus is provided. The molding apparatus includes a first block configured to receive a moldable article therein, a second block positioned a distance from the first block, and a shim including graphite. The shim is positioned between the first block and the second block, wherein the shim gradually disintegrates when heated such that the second block contacts the first block.

Abstract: A composition suitable for forming a support using a three-dimensional (3D) deposition method is presented. The composition includes a wax including at least one functional group capable of reacting with a build material used in the 3D deposition method, when exposed to an actinic radiation, wherein the functional group is itself substantially non-reactive to the actinic radiation. A method of forming a three dimensional (3D) article is also presented.

Abstract: Compositions and methods useful for forming ceramic articles, such as, for instance, cores and shells for investment casting, are provided. The composition comprises a liquid that comprises a siloxane species; a plurality of particles, comprising a ceramic material, disposed within the liquid; a catalyst material disposed within the liquid; and a pore-forming agent disposed within the liquid. The pore-forming agent comprises a silicon-bearing agent that is substantially inert with respect to the liquid, and has an average molecular weight less than about 1300 grams per mole. The method comprises disposing any of the compositions described above in a desired shape; curing the siloxane species, and volatilizing the pore-forming agent to form a porous green body.
