In view of the existing problems of complexity of process parameters and the difficulty in determining the optimal process in the field of 3D printing, polylactic acid (PLA) samples were prepared by fused deposition modeling (FDM). Orthogonal experiments were designed with 3D printing parameters (layer height, filling density and printing speed) as factors. The effects of layer height, filling density and printing speed on the tensile and compressive properties of PLA were studied. When layer height is 0.15 mm, the filling density is 100%, and the printing speed is 30 mm/s, the sample has the best comprehensive mechanical properties.
