Patent ID: 8813824

Claim:
A device comprising: a ceramic or wax first form comprising: a first plurality of surface artifacts that are integral to the first form and that substantially spatially replicates a surface geometry of a first stacked foil mold from which the first form descended, wherein: the first plurality of surface artifacts resemble seams but do not extend substantially below a surface of the first form; and each surface artifact from the first plurality of surface artifacts geometrically replicates a thickness of a foil of the first stacked foil mold; and a first prong that: has a predominantly ceramic composition; is integral to the first form; is structurally configured to form a first hole in a metallic cast product that is cast in a molten state substantially around the first prong; is structurally configured to substantially structurally disintegrate due to thermal stresses imparted on the first prong as the metallic cast product cools from a molten state to a solid state; and defines a prong longitudinal axis, an intersection of the first form and the first prong defining a fillet that is integral to the first prong and the first form, the fillet defining a first midpoint fillet depth measured in a first plane that contains the prong longitudinal axis, the fillet defining a second midpoint fillet depth measured in a second plane that contains the prong longitudinal axis, the first plane separated from the second plane by a predetermined angle measured perpendicular to the prong longitudinal axis, the fillet comprising one or more surface artifacts from the first plurality of surface artifacts.
