摘要：
Aiming at the problem on surface roughness of fused deposition modeling parts, the influence of key process parameters on surface roughness was analyzed by experimental method, and the influence of layer thickness and extrusion width on surface roughness was analyzed emphatically. The change of wire section and the formation process of side surface profile were studied in the process of forming, and the prediction model of surface roughness was established and verified by experiments. The results show that the average relative errors of the predicted surface roughness and the measured surface roughness are 6.25% and 5.04%, respectively, which proves the feasibility of the model. © 2020, Central South University Press.
