摘　　要：以聚苯乙烯(PS)粉末为基底材料的快速烧结原型件力学性能较差,通常达不到使用要求,为改善其力学性能,采用浸渍环氧树脂(EP)固化体系增强后处理的方法,使部分EP浸入原型件的空隙中,利用扫描电子显微镜对材料断裂面的形态结构进行了研究,并对测试件的拉伸性能、冲击性能等进行了测试,证明原型件经增强后处理,各项性能都得到了很大的改善。The mechanical properties of polystyrene（PS） powder rapid sintering pieces was had and could not achieve the use requirements. For improving the mechanical properties, PS was post-processed by soaking epoxy resin（EP） curing system and partial EP was plunged in prototype crevice. The morphology of rupture surface was studied by scanning electron mieroscpoe, and the tensile strength and impact strength of testing samples were tested. The results showed that various performances were improved after enhancement post-processed.
