Abstract Soligen Technologies' Direct Shell Production Casting (DSPC), enables production of a functional metal prototype or parts without a production tool. DSPC works by producing ceramic molds directly from a CAD file, which are then poured with any metal alloy, obtaining a fully functional part in a matter of days. A ceramic mold can be made with an integral core, which separates it from other rapid prototyping methods that have no way of incorporating complex cores in their plastic, wax, or paper patterns. XX
