Due to the limited low performance material choice, selective laser sintering (SLS)of polymers is limited to prototyping applications. There is a need to produce SLS 3D print production-grade parts. Here presents a study to evaluate the processibility of a high performance polymer, Polyphenylene Sulfide (PPS). It has a high heat resistance as well as a good mechanical strength. When it mixes with fillers such as ceramic particulates, PPS powders can have improved processiblity and mechanical properties on the SLS parts. The powder’s rheology was characterized. Various combinations of process parameters, such as laser power, scan speed and chamber temperature, were used to determine the best resulting SLS parts. SLS ASTM tensile specimen was used to determine the mechanical characteristics.
