AN ADDITIVE MANUFACTURING SYSTEM WITH A MULTI-ENERGY BEAM GUN AND METHOD OF OPERATION

摘要

An additive manufacturing system includes an energy gun having a plurality of energy source devices each emitting an energy beam. A primary beam melts a selected region of a substrate into a melt pool and at least one secondary beam heat-conditions the substrate proximate the melt pool to reduce workpiece internal stress and/or enhance micro-structure composition of the workpiece.
