Title:
COMBINED ADDITIVE MANUFACTURING METHOD APPLICABLE TO PARTS AND MOLDS
Document Type and Number:
WIPO Patent Application WO/2018/091000
Kind Code:
A1
Abstract:
A combined additive manufacturing method applicable to parts and molds, relating to the field of parts and molds manufacturing by mold-free forming, and comprising the following steps: S1, according to the shape, thickness and dimensional accuracy of the workpiece to be formed, layer processing of the 3D CAD model of said workpiece is performed, to obtain multi-layer slice data; S2, on the basis of the multi-layer slice data, planning of the forming steps is undertaken, and the required numerical control code is generated for each layer; S3, on the basis of the numerical control code for each layer obtained in S2, powder material is stacked layer by layer on a substrate to form the shape that is then further processed by pressure treatment or milling; the layer by layer forming utilizes a numerically-controlled high-speed cold-spray gun to apply the powder material to the designated locations and thus build up the form by stacking. The present method overcomes both the undesired effects of heat processing and the defects of cold-spray stacking.
