摘　　要：目前微小零部件的制造方法很多,激光微成形即为其中一种。介绍了在激光选区烧结技术的基础上,结合微成形特点开发的激光微区烧结成形技术。该技术可对金属粉末进行直接微区烧结成形,所成形的金属微型零件强度高,不需后续处理,大大节省了从原材料到最终实体的时间,并具有环境污染小、材料利用率高、成形速度快和效率高的特点。Many methods were developed to fabricate micro parts. Laser micro-fabricatlon is used to process micro part recent year, In this paper we report the newly developed laser micro sintering technology to manufacture micro part with metal powder directly. This technology, which is based on selective laser sintering（SLS）, sinters metal powder in a tiny area using focused tiny spot layer by layer. The powder is deposited with a special micro powder feeding device instead of rolling powder device in SLS,.
