为提高金属模具材料的性能，研究了激光增材技术(3D打印)、激光熔覆技术和激光淬火技术等。结果表明：激光3D打印技术制备的镍基合金表面结晶细致均匀，可用于制造模具镶块材料。在25号钢上激光熔覆钴基合金制备的模具材料的硬化层深度可达1.45 mm，模具硬度达到维氏硬度500以上。半导体激光淬火处理作为H13钢热处理的最后一道工序，使模具钢的硬度提高了50%以上。

In order to improve the performance of metal mould material,three kinds of manufacturing laser processing technolo-gy were used in this paper:material increasing technology (3D printing), laser cladding technology and laser quenching technique. The results showed that:nickel base alloys prepared by crystalline 3D laser printing technology were uniform, which could be used in the manufacture of the mold insert material. The depth of the cobalt base alloy on the 25# steel surface was1.45mm, and hardness was more than HV500. Hardness of H13 steel after laser quenched increased more than 50%.
