Sand molding for metal additive casting

Abstract

A casting system for casting an object, wherein the casting system may include a mold system, a replaceable material provision system, and a molten metal processing system. The casting system may be configured to additively produce multiple production layers, one currently-produced production layer after the other. For each currently-produced production layer: (i) the mold system is configured to form one or more mold-layers, (ii) the replaceable material provision system is configured to provide one or more replaceable material layers; and (iii) the molten metal processing system is configured to form one or more current object regions of the currently-produced production layer by providing molten metal that replace the one or more replaceable material layers.
