摘要
现在已经市场化的选择性激光烧结用高分子粉末烧结制件强度低,需要经过后处理才能满足使用要求。针对此问题,本文采用尼龙-6/聚苯乙烯体系复合材料作为选择性激光烧结的基体粉末,探讨氧化铝的加入方式对粉末烧结性能的影响,获得了烧结精度和力学性能都良好的制件。探讨了主要工艺参数对烧结性能的影响,并通过正交试验确定了尼龙-6/聚苯乙烯粉末体系优化的烧结工艺参数:激光功率10W,扫描速率1500mm·s-1,扫描间距0.15mm,铺粉层厚0.20mm。
The mechanical strength of high molecular materials already used in SLS is too low to satisfy the demand without post - treat- ment. To solve this problem, nelon -6/PS composite materials were selected to act as SLS materials in this paper. The addition pattern of Al2O3 was studied. As a result, good sintering and mechanical properties were obtained. The influence of SLS parameters on sintering properties was studied, and the optimum parameters were decided by orthogonal experiments： laser power 10W, scanning rate 1,500 mm·s^ -1, scanning space 0.15 mm, layer thickness 0.20mm.
