Description

technical field [0001] The invention belongs to the technical field of materials, and relates to a melting coating forming device and method, in particular to a melting coating forming device and method of a metal material gradient member. Background technique [0002] Additive manufacturing technology (also known as "3D printing") is rapidly changing traditional production and lifestyles. Its core idea is to discretize three-dimensional parts in two dimensions to form layered data. According to the layering of the three-dimensional CAD model of the part Data, the discrete forming materials are gradually combined to form layered cross-sections, and then piled up layer by layer to form solid parts. The parts can be directly manufactured without molds, which can greatly reduce costs and shorten the development cycle. At present, relatively mature metal parts additive manufacturing technologies mainly include laser rapid prototyping, such as selective laser melting (Selective L...
