Claim Text:
1. A molding, method comprising: injecting, a metal powder-liquid binder slurry into a disposable mold formed from at least one of an ultraviolet curable acrylic or a photosensitive material and having internal walls that form a negative imprint of a complex three-dimensional geometry of a complex three-dimensional metal part, wherein the volume of the metal powder-liquid binder slurry is substantially equivalent to the volume of the complex three-dimensional geometry; heating the disposable mold and the metal powder-liquid binder slurry therein to form a cured, complex three-dimensional structure from the metal powder-liquid binder slurry, the liquid binder in the metal powder-liquid binder slurry being cured by the heating; removing the disposable mold from the cured, complex three-dimensional structure to release the cured, complex three-dimensional structure, wherein removing the disposable mold from the cured structure comprises removing the binder from the cured, complex three-dimensional structure to form the complex three-dimensional metal part; and sintering the complex three-dimensional metal part.
