METHOD FOR MANUFACTURING NON-SUPPORT LASER ADDITIVE MATERIAL APPLIED TO DIFFICULT-TO-MACHINE OVERHANGING STRUCTURE IN EASILY-DEFORMED METAL MATERIAL

原文（中国語）

A method for manufacturing a non-support laser additive material applied to a difficult-to-machine overhanging structure in an easily-deformed metal material, forming a metal non-supported overhanging structure by adopting a laser powder melting the metal power, in a process of laser-melting metal powder layer by layer to form forming layers of the metal non-supported overhanging structure, when a current forming layer is equipped with an overhanging area relative to a previous forming layer, the overhanging area of the current forming layer is formed by a S1 forming strategy; when the previous forming layer is equipped with an overhanging area, an area where the overhanging area of the current forming layer overlaps with that of the previous forming layer is formed by a S2 forming strategy; and remaining areas are all formed by a S0 forming strategy.
