Optimization Method of FDM3D Printers Parameters for Energy Efficiency Based on Taguchi

为研究工艺参数与FDM3D打印机能效耦合的复杂机理,提出一种基于田口法的FDM3D打印机工艺参数能效优化方法。通过设计田口法实验,采集了FDM3D打印机加工过程的能耗以及加工时间数据。采用信噪比分析实验数据,确定能耗和加工时间与工艺参数的关系。研究显示在实验范围内,较低的热床温度和喷头温度,以及较大的打印速度和分层厚度,可大幅减少FDM打印时间,有效降低FDM打印能耗。针对自行研制的FDM 3D打印设备,分别给出了面向最高能效和最高打印效率的优化工艺参数组合。

To study the complex interaction between the process parameters and the energy efficiency of FDM3D printers,an optimization method of FDM3D printers parameters for energy efficiency based on Taguchi method is proposed.This method employs a Taguchi method experiment to acquire the energy consumption and processing time of the FDM3D printer process.And then,the Signal to Noise Ratio is utilized to analysis experimental data and hence to determine the relationship between energy consumption and processing time and process parameters.Research shows that low hot bed temperature and nozzle temperature,and the larger the printing speed and layer thickness can significantly reduce the FDM printing time and effectively reduce the energy consumption of FDM print in the experimental range.In view of the FDM3D printing equipment developed by ourselves,the optimization process parameters combination for the highest energy efficiency and the highest printing efficiency are given respectively.
