Method of rapidly making casting, comprising: designing a computer graphic model of the casting; sectioning the graphic model into graphic members which are at least one of blocks and slabs; carving a solid member for each of the graphic members, the solid members being (i) constituted of a meltable or evaporative solid material (i.e. wax or polystyrene), (ii) proportional to and enveloping its corresponding graphic member, and the carving being carried out by accessing two or more sides of each solid member to at least essentially duplicate the corresponding graphic member; forming a mold around the pattern, and casting metal within the mold while removing the pattern from such mold either by evaporation during pouring of the molten metal thereinto or by melting prior thereto.

Rapidly making complex castings

Method of rapidly producing a contoured part, comprising: designing a computer graphic model of the part, sectioning the graphic model into graphic members which are at least one of blocks or slabs, carving a solid member (14-150 mm in thickness) for each of the graphic members, the solid member being proportion to and enveloping such graphic members, the carving being carried out by accessing two or more sides (opposite sides) of such solid member to at least essentially duplicate the corresponding graphic member, and securing the carved solid members together to replicate the graphic model as a usable unitary part. The method can be modified to make castings by carving wax or foam solid members which are assembled to form an investment pattern, the was pattern being used in a shell mold casting steps and the foam pattern being used in evaporative casting steps.
