摘要：In the process of selective laser sintering, the forming parameters will affect the dimensional accuracy and performance of the forming parts. At present, there is no reference standard for the optimal forming parameters of PA material. Aiming at this problem, the three factors of laser power, scanning pitch and scanning speed are analyzed, and the influence of the tensile strength of PA2200 material forming parts is analyzed. Through theoretical and experimental analysis, the optimal combination of process parameters is obtained by orthogonal experiment. The best combination of parameters is laser power 40W, scanning speed 3000mm/s, scanning pitch 0.4mm, and tensile strength up to 46.42MPa.
