其他建议： Additional Suggestions： 1. 如果想实现高速打印，推荐使用近程挤出机，例如：BMG挤出机、Titan挤出机、Hemera挤出机，并适当提高喷嘴温度。 If you want to achieve high-speed printing, it is recommended to use direct extruders, such as BMG extruder, Titan extruder and Hemera extruder, and appropriately increase the nozzle temperature.
2. TPU材料暴露在空气中容易吸收水分，吸湿后打印会出现拉丝，挤出有气泡，打印表面粗糙等现象，降低打印质量。建议您打开FusFlexTM TPU78D真空铝箔袋包装后立即将线材放入干燥盒内（湿度控制在15%以下）进行打印。不用的线材请放回原包装铝箔袋内密封保存。 TPU material is very easy to absorb moisture when exposed to air, and printing after absorbing moisture will result ozzing, extruding with bubbles and rough surface appearance, thus reducing print quality. It is recommended that put the filament into a dry box (humidity below 15%) immediately after opening the FusFlex™ TPU78D vacuum foil bag for printing. Please put the unused filament back into the original aluminum foil bag for sealed storage.
3. 材料受潮后会出现打印拉丝增多，挤出有气泡，打印表面质量粗糙等现象。请将线材放入70-80℃烘箱内干燥4-6h，即可恢复FusFlexTM TPU78D的打印质量。 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 70-80°C for 4-6h to restore the printing quality of FusFlex™ TPU78D. | |
