Abstract: Generally, compositions and methods of producing dimensionally stable three dimensional objects using an additive build up process. Specifically, materials combinable in an additive build up process using a materials printer for the production of stable three dimensional molds useful in the production of molded or formed parts.
Abstract: A mold material castable to provide a mass reduced work piece machinable to produced a mold and methods of utilizing such mold material to cast mass reduced work pieces machinable to produce a mold.
