Description

Technical field [0001] The invention belongs to the technical field of materials, and relates to a melt coating forming device and method, in particular to a metal material gradient member melt coating forming device and method. Background technique [0002] Additive manufacturing technology (also known as "3D printing") is rapidly changing the traditional production and lifestyle. Its core idea is to discretize three-dimensional parts in two dimensions to form layered data, which is layered according to the three-dimensional CAD model of the part. Data, the discrete forming materials are gradually combined to form a layered section, and then stacked layer by layer to form solid parts, without molds, directly manufacturing parts, 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 Malting (SLM), Direct Metal Laser Sintering (D...
