| Abstract: | Compressive strength is one of the important factors affecting the reliability of 3D printed parts.In order to determine the main process parameters affecting the compressive strength,a set of L8 orthogonal test was designed by using the Taguchi method,and the pressure test was carried out.The process parameters were studied by analysis of variance,and the printing direction and printing temperature were preliminarily determined to affect the compressive pressure.The main factors of strength;through the experimental data,combined with the two-parameter Weibull distribution model,the reliability analysis of the compressive strength of 3D printed parts is completed,and the quality of 3D printed parts is improved by optimizing the process parameters. |
