Abstract

One purpose of the invention is to provide a forming method. The method can solve the problem of excessive support in the forming process of a part with a cantilever structure. Another purpose of theinvention is to provide a forming part with a cantilever structure. The forming method comprises the steps that a part model is obtained, an inclined supporting part is added to the cantilever structure, the model is layered and sliced, and a formed layer is subjected to scanning path planning. In the formed layer forming an inclined plane, a to-be-formed layer is provided with a suspended area and a non-suspended area which protrude out of the formed layer, a frame scanning path is composed of a first path and a second path, the first path corresponds to the non-suspended area, and the secondpath corresponds to the suspended area. Preparation process parameters are set for the first path and the second path according to the inclination angle, and printing is carried out layer by layer according to the set preparation process parameters. The energy density in the first path preparation process parameter is less than the energy density in the second path preparation process parameter.

Description

technical field [0001] The invention relates to an additive manufacturing technology, in particular to a formed part with a cantilever structure and a forming method thereof. Background technique [0002] Additive Manufacturing (AM) technology, as an emerging manufacturing technology, has developed rapidly in recent years. Laser Melting Deposition (LMD) technology is an advanced technology developed on the basis of Rapid Prototyping (RP). Compared with the traditional forging-machining forming technology, the direct energy deposition additive manufacturing technology has: (1) high material utilization rate and small machining amount; (2) less production process, simple process, and high (3) The forming process does not require molds, the manufacturing cost is low, and the cycle is short, which can greatly meet the low-cost manufacturing of high-melting point, difficult-to-process, and expensive metal materials, and is widely used in Aerospace, automobile, ship and other fie...
