摘　　要：研究在选择性激光烧结(SLS)过程中,复合尼龙粉末激光烧结工艺参数的优化。讨论激光功率、预热温度、扫描速度、铺粉厚度等工艺参数对制件强度的影响。采用正交试验的方法,在不同工艺参数下将复合尼龙粉末烧结成9组哑铃状试样,以强度为指标,计算出强度最好的工艺参数组合,并结合比较试件的尺寸精度得到激光烧结复合尼龙材料的最优工艺参数为:激光功率14W,预热温度95℃,扫描速度1400mm/s,铺粉厚度0.1mm。This paper studies the optimum sintering parameters ot laser smtermg nylon composites in Selective Laser Sintering process and discusses the effects of sintering parameters, including laser power, preheating temperature, scanning speed and power bed depth on the strength of parts. The nylon composites were sintered to nine dumbbell-shape parts with different sintering parameters determined by orthogonal design. By comparing the strength and dimension of parts, the optimum sintering parameters of laser sintering nylon composites is obtained： laser power of 14 W, preheating temperature of 98 ℃, scanning speed of 1 400 mm·s^-1 and power bed depth of 0.1 mm.
