Abstract
A combined additive manufacturing method applicable to parts and molds relates to moldless-growth manufacturing of parts and molds, which includes steps of: S1: layering and slicing a three-dimensional CAD (computer-aided design) model of a workpiece to be formed according to shape, thickness and dimensional accuracy requirements of the workpiece, so as to obtain a plurality of layered slice data; S2: planning a forming path according to the layered slice data, and generating layered slice numerical control codes for forming; and S3: deposition-forming a powder material on a substrate layer-by-layer and performing pressure forming or milling forming according to the layered slice numerical control codes in the step S2, which uses a numerically controlled high-speed cold spray gun to spray the powder material to a determined position for deposition-forming. The method of the present invention overcomes thermally induced adverse effects of hot processing and drawbacks of cold spray deposition.
