Optimization of 3D Printing Parameters on Surface Roughness and Flatness of PLA Using Taguchi Design of Experiments
摘要
The objective of this research was to evaluate the influence of some parameters of 3D printing on the rough surface and flatness of the parts. For the study, all samples were produced from polylactic acid (PLA), following the Taguchi experimental design method. The printing parameter settings that optimised the roughness and flatness were firstly determined. Layer height, print speed and nozzle temperature were the key printing parameters used to devise the experiments. The experiments were defined by varying these according to the Taguchi L9 orthogonal array. Surface roughness in different orientations (X, Y, Z) and angles (15°, 30°, 45°, 60°, 75°) was then measured whereas flatness was evaluated based on the standard deviation from the value of a reference plane. This study potentially opens a new door to manufacturers to enhance surface finish and dimensional accuracy for various 3D printed components.
