基于粉体喂料3D打印机的热塑性聚氨酯弹性体成型工艺参数研究

Molding Process Parameters on Thermoplastic Polyurethane Elastomers for Powder Feeding 3D Printing

基于粉体喂料3D打印机,以拉伸强度为试验指标,采用正交试验方法确定了颗粒状热塑性聚氨酯弹性体的最佳成型工艺参数为:机筒温度215℃,螺杆转速8 r·min^(-1),喷头温度230℃,打印平台温度45℃。通过打印轮胎和蜂窝状模型验证了最佳成型工艺参数的合理性。

Based on the powder feeding 3D printer,using tensile strength as an index,the best molding process parameters of granular thermoplastic polyurethane elastomers were determined by the orthogonal test method as follows:barrel temperature 215 ℃,screw speed 8 r·min-1,nozzle temperature 230 ℃,and print platform temperature 45 ℃. The best molding process parameters were verified by printing tire and honeycomb model.
