摘要： The invention is a system for and method of manufacturing metallic parts through weld arc additive manufacturing with conductive granular media as support, to manufacture parts which have overhangs, hollow sections, a plurality of openings, a geometry having a discontinuous structure when formed by additive manufacturing steps that is joined, or a combination of geometries known in the art of manufacturing that could heretofore only be produced by cutting and assembling a variety of different parts. The system and method of the invention contemplate use of conductive granular media support material which may become at least partially incorporated in, or part of, a final part produced using the system or method of the invention.
