Abstract: According to some aspects, a method is provided of casting an object from a mold, the method comprising obtaining a mold comprising a hollow shell of rigid material, the material comprising a thermoset polymer having a plurality of pores formed therein, providing a metal and/or ceramic slurry into an interior of the mold, exposing at least part of the mold to a low pressure environment so that a net flow of gas is produced from the interior of the mold into the low pressure environment. According to some aspects, a method of forming a porous mold is provided. According to some aspects, a photocurable liquid composition is provided, comprising a liquid photopolymer resin, particles of a solid material, in an amount between 30% and 60% by volume of the composition, and a water-soluble liquid.

Abstract: Disclosed herein is a method of forming a mold comprising disposing a film having a textured surface on a support; where the support has a shape of an article to be manufactured; pressing the film onto the support to cover a surface of the support; disposing a backing on the film; separating the support from the backing; and molding a material in the backing. Disclosed herein too is a method comprising contacting a first mandrel with a first mold; where the first mold has a textured surface; texturing a surface of the first mandrel with the first mold; disposing the first mandrel in a die; disposing a first material in the die to contact the first mandrel; imparting a texture from the surface of the first mandrel onto the material to form a second mold; and disposing a texture from the second mold onto a second material; where the second material is different from the first material.
