其他建议: 1. 纯铜喷嘴耐磨性较差,建议选用不锈钢或硬化钢喷嘴打印,可以有效提高打印质量。 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. The wear resistance of copper nozzle is poor. It is recommended to use stainless steel or hardened steel nozzle to print, which can effectively improve the printing quality. 2. Please put filament into a dry box, which can effectively reduce the oozing, rough surface and so on. |
