摘要
面向快速铸造工艺的激光选择性烧结(SLS)工艺制造可以制造可烧蚀的高分子快速原型,结合熔模铸造工艺能够实现金属零件的无模快速铸造。选择既适合激光烧结工艺又满足铸造要求的高分子材料是快速铸造工艺的前提。在系统地比较和分析了常用高分子材料的特性,并进行了粉末激光烧结实验后,选择了聚苯乙烯(PS)材料作为快速铸造用SLS原型的粉末原材料。
The polymer rapid prototype made by selective laser sintering （SIS） process could be burned out, so the metallic parts could be rapidly manufactured without moulds by combing casting process with SIS prototype. It is the precondition of rapid casting process to select polymer material that meet the case of bath laser sintering and casting process. The characteristics of common polymer materials are compared and analyzed systematically, and the laser sintering experimentation of polymer material powder is carried out, in which polystyrene （PS） is selected to be the raw material of SIS prototype powder for rapid casting process.
