摘　　要：对复合尼龙粉末材料激光烧结成型的加热过程进行了分析,在此基础上研制了一种适合于粉末材料激光烧结成型过程温度场的测试系统。该系统利用红外测温仪测量粉末表层温度,利用热电偶测量粉末内部温度,测量结果由计算机打印输出。根据输出结果成功进行激光烧结工艺参数优化。Based on analyzing the laser sintering course of composite nylon powder, a measuring system was developed to study the laser sintering temperature field. Infrared meter was introduced to measure the surface temperature of sintering powder, and the temperature of inside part was measured by using of thermo-couple method, with the testing data processed by computer. The laser sintering parameter was optimized successfully according to exported results.
