Abstract A selective laser sintering (SLS) pattern made of polystyrene (PS) is not suitable for investment casting of complex parts due to its poor mechanical properties. Therefore, high impact polystyrene (HIPS) should be used to make complex parts. The sintering characteristics of HIPS are as good as those of PS, and the mechanical properties are much higher than those of PS. In order to further improve the performance, post-processing is employed infiltrating with wax in this study. Through… CONTINUE READING
