其他建议： 1. PET材料虽然吸湿率极低，但对水分却非常敏感。材料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FusForceTM PET-GF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。 2. 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100-120℃烘箱内干燥4-6h，即可恢复FusForceTM PET-GF的打印质量。 3. 建议选用Phaetus硬化钢及以上等级喷嘴，可以有效提高打印质量，建议加热块厚度不小于12mm。 4. 打印完成后可以对打印件进行退火处理，可以进一步提高FusForceTM PET-GF打印件的强度，退火条件：80-100℃温度下放置4-8小时后自然冷却到室温。
Additional Suggestions: 1. Although the moisture absorption of PET material is very low, it is very sensitive to moisture. Printing after absorbing moisture will result in 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 FusForceTM PET-GF vacuum foil bag for printing. Please put the unused filament back into the original aluminum foil bag for sealed storage. 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 100-120℃ for 4-6h to restore the printing quality of FusForceTM PET-GF. 3. Phaetus hardened steel and above grade nozzles shall be selected, which can effectively improve the print quality. Besides, it is recommended that the thickness of the heating block should no less than 12mm. 4. After the printing, the printed part can be annealed to further improve the strength of FusForceTM PET-GF print part. Annealing conditions: place the printed part at 80-100℃ for 4–8 hours and cool to room temperature naturally. | |
