摘　　要：介绍了选择性激光烧结制造不锈钢成型件的工艺,以及在此基础上的脱脂降解和高温烧结后处理实验,并分析经过后处理的成型件组织和性能.真空烧结后的原型件没有发生金属氧化现象,表面呈现金属光泽,经真空烧结后的原型件体积收缩较大,致密度提高,质量减少约8％～9％.通过对真空二次烧结的研究发现,烧结温度比烧结时间对原型件的影响更大,高温烧结后,原型件强度大幅度提高.This study introduces the technological process of manufacturing stainless steel parts using the selectivity laser sintering （SLS） technique and the post treatment experiment of degreasing,heat Sintering based on the process,and analyzes the organization and function of the part after post treatment.The prototype part after sintering in vacuum,no metal oxidation,surface is metallic luster,after vacuum sintered prototype of volume shrinkage,density increased,the quality was reduced by about 8％ ～ 9％.Through the study of vacuum two sintering,sintering temperature is greater than the sintering time effect on the prototype parts,high temperature sintering,the prototype part strength greatly increased.
