In order to study the impact of fused deposition(FDM)3D printing process parameters on the molding accuracy of parts and improve the application level of polylactic acid(PLA)materials in this technology,four aspects including printing speed,layer thickness,printing temperature and filling rate were focused on the influence of factors on the dimensional accuracy of parts.Based on the four-factor and four-level orthogonal test method,a range analysis was performed on the measurement re-sults of the dimensions of the printed parts,and the optimal printing parameters were found to be a printing speed of 50 mm/s,a layer thickness of 0.10 mm,a printing temperature of 210℃,and a filling rate of 15％.The results of multi-factor variance analysis show that:printing speed and filling rate will affect the dimensional accuracy in the X and Y directions.Filling rate and layer thickness will affect the dimensional accuracy in the Z direction.
