Abstract

A lost wax molding system has a re-usable, collapsible, chain-linked mesh exoskeleton, one or more inserts to be placed within the interior surface of the mesh exoskeleton to exert outward pressure on the mesh exoskeleton thereby creating a pre-formed, rigid, three-dimensional shape, a waterproof sleeve sized to cover the outer surface of the three-dimensional shape, and a base sized to seal said waterproof sleeve forming an investment mold container.
