基于正交试验的FDM 3D打印工艺方法研究

正交实验设计和分析方法是研究多因素多水平工艺优化实验的有效方法。针对目前3D打印领域缺乏行业标准、影响3D打印成型结果的工艺参数繁多、最佳工艺流程难以确定的问题,采用正交实验方法研究影响3D打印成型质量的工艺流程,分析出层高设置、打印速度、填充密度依次为影响FDM(熔融沉积)3D打印成型的主要因素,并得出层高0.18mm,打印速度40 mm/s,填充30%时表面质量较好。正交实验方法对优化3D打印工艺流程、提高打印效果具有借鉴意义。

Research of FDM 3D Printing Technology Method Based on Orthogonal Experiment

Orthogonal experimental design and analysis method is an effective method to study the technology optimization experiment with multiple factors and levels. On the present issue of three dimensional (3D) printing standard deficiency and the different and varied technological influence parameters, which was difficult to determine the optimum process for 3D printing modeling, the orthogonal experiment was used to study the 3D printing technological process, and analyzeded the influence to the Fused Deposition Modeling (FDM) of modeling quality by related factors which were, in order, the layer height setting, print speed and packing density. The results show that the best quantization parameters of each factor are 0.18 mm, 40 mm/s and 30% for the surface quality. The orthogonal experiment method has a reference meaning for optimizing the 3D printing technology process and improving the printing qualities.
