其他建议: Additional Suggestions: 1. 纯铜喷嘴耐磨性较差,建议使用不锈钢或硬化钢喷嘴打印,可以有效提高打印质量,同时在选用钢制喷头后需要提高一定的喷头温度。 2. 在打印过程中将线材放入干燥盒内,可以有效减少拉丝,表面粗糙等现象。 Additional Suggestions: 1. Phaetus hardened steel and above grade nozzles shall be selected, which can effectively improve the print quality. 2. After the material is damp, there will be more printing ozzing, bubbles extruded and rough printing surface. Please dry the filament in an oven at 60-70℃ for 4-6h to restore the printing quality of FusFunTM PETG-Matte. |
