Rapidly making complex castings

Method of rapidly making castings, 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 mould around the pattern, and casting metal within the mould while removing the pattern from such mould either by evaporation during pouring of the molten metal thereinto or by melting prior thereto.
