Zusammenfassung:	A system and a method of fabricating a complex three dimensional part are described. The system comprises a rapid prototyping machine configured to provide a disposable mold having a negative imprint of a complex three dimensional structure, a mixer, an injection molding machine, and a furnace system. A slurry comprising a powder and a binder is introduced into the disposable mold, the binder is cured, the disposable mold is removed, and the binder is removed, leaving an intact cured structure. The cured structure is sintered to fabricate the complex three dimensional part.
