摘　　要：研制开发了几种复合蜡粉,经过烧结测试,筛选出了一种适合激光选区烧结用精铸蜡粉。研究了激光烧结性能和烧结成型工艺,得到了激光烧结成型最佳工艺参数。结果表明,筛选出的精铸蜡粉最佳烧结为激光功率10 W、预热温度60℃、激光扫描速度2 000 mm/s、铺粉厚度0.15 mm。Several kinds of composite wax powders were developed, and a kind of precision casting wax powder suitable for laser selective sintering was selected through sintering test. The performance and sintering process of laser sintering were studied, and the optimum technological parameters of laser sintering were obtained. The results show that the selected precision casting wax powder is optimized for sintering with laser power of 10 w, preheating temperature of 60 ℃, laser scanning speed of 2,000 mm/s and powder thickness of 0.15 mm.
