In this study, a new type of friendly environment material including polyether sulphone resin powder (PES), and limestone flour (CaCO 3 ) (referred to as CO-PES-CaC) has been developed for selective laser sintering (SLS) additive manufacturing that is low cost, environmentally friendly and energy efficient. The aims of this study were to optimization of PES/CaCO 3 composite powder for SLS printing technology. The mechanical properties and microstructure of CO-PES-CaC affected by different the ratio of PES powder and CaCO 3 powder has been studied. The experimental results indicate that the CO-PES-CaC quality was optimum when the ratio of PES powder and CaCO 3 powder was 75/25. The mechanical properties peak at 8.09 MPa for tensile strength and 15.28 MPa for flexural strength, and 3.91 kJ/m 2 for impact strength.
