“…There are few reports on the research on the process parameters of PA forming parts. In view of the above problems, PA2200 powder was selected as the research object, and the dimensional accuracy of the formed part was used as the evaluation index to study the influence of scanning distance and scanning speed on the dimensional accuracy of the formed part, and the optimal combination of process parameters was obtained by orthogonal experiment [7] .…”

In selective laser sintering powder forming, the performance and dimensional accuracy of the formed part are affected by the process parameters. Different materials have different process parameters, and there is still no reference standard for PA materials. To solve this problem, in response to this problem, PA2200 material was selected, and the influence of scanning interval and scanning speed on the dimensional accuracy of the formed part was analyzed. Through theoretical analysis and experiments, the optimal process parameters were obtained. The best combination of parameters is a scanning speed of 4000mm/s, a scanning interval of 0.5mm, and the size of the molded part has a X-axis deviation -0.35%, a Y-axis deviation -0.4%, and a Z-axis deviation -0.25%.
