Abstract

A metal additive material manufacturing support method based on a shape following base plate is used for reducing the distance between a supporting point and a base plate, various generated support areas serve as a base, the shape following base plate related to the surface of a formed component is downwards established, a new support is generated on the shape following base plate, and accordinglythe support height is lowered. The shape following base plate can guarantee the generated support forming quality along with constant changes of the height, the shape and the thickness of the formedface. A metal additive material manufacturing support device based on the shape following base plate is provided. When formed components are complex in shape and structure and the support areas are high, on one hand, a conical support can be continuously utilized, materials are saved, and the removal difficulty is lowered; and on the other hand, the height of the support, making contact with the formed bottom face, of the base plate can be effectively reduced, and the component bottom face and structure forming quality is improved.
