Polystyrene (PS) is a widely used matrix material in selective laser sintering (SLS). Polystyrene is inexpensive and its powdered form, used as a matrix material in selective laser sintering, enables high accuracy in prototype production, similar to the casting process of wax molds. However, the performance of polystyrene varies significantly due to the differences in its synthetic process and added fillers of different grades available in the market, leading to varying outcomes when used in selective laser sintering technology. Therefore, it is necessary to study the polystyrene materials ava...
