In this study, we performed the optimization study of selective laser sintering (SLS) 3D printing mode for the material is a mixture of Green Bean Powder and Polylactic acid powder (GBP/PLA) to createed a new biodegradable synthetic material (GBCP). The study was designed with 2 factors changing: print speed and laser power, fixed factor is the ratio of GBP/PLA is 20/80. Through Scanning Electron Microscope (SEM) to assess the structure of materials; tensile strength, flexural strength and impact strength evaluate the mechanical properties of materials. Experimental results show that with the printing speed of 2 m/s, the printing power of 21W, the GBP/PLA material has the best quality with a tensile strength of 2.89 MPa, flexural strength of 5.91MPa and impact strength is 0.57KJ.m 2 .
