NexPA-CF25 – FUSROCK

TDS技术文件

共挤包覆结构25%短切碳纤维增强高温尼龙3D打印材料。

产品简介

FusCoating™ NexPA-CF25是一款具有双层包覆结构的25%碳纤维增强高温尼龙3D打印线材。线材外层为高粘接强度的纯尼龙树脂，线材内芯为短切碳纤维增强的高温尼龙。FusCoating™ 3D打印包覆线材利用了高分子熔体在挤出过程中一般为层流运动的特性，线材在通过打印机喷头后仍能保持稳定的双层包覆结构，打印时的Z轴层间方向可以始终保持为外层的纯树脂之间粘接，大幅度提高了纤维增强类FDM材料的Z轴层间强度，同时25%填充含量的短切碳纤维又进一步提高了打印零部件件的整体机械性能与耐热性，非常适合打印薄壁类和高机械性能要求的零部件。

其他建议：

Additional Suggestions：

1. 尼龙材料非常容易吸收环境内的水分，吸湿后打印会出现拉丝，挤出有气泡等现象，降低打印质量。建议您打开FusCoating^TM NexPA-CF25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。

Nylon material is very easy to absorb moisture within the environment, 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 FusCoating^TM NexPA-CF25 vacuum foil bag for printing. Please put the unused filament back into the original aluminum foil bag for sealed storage.

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80-100℃烘箱内干燥4-6h，即可恢复FusCoating^TM NexPA-CF25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 80-100℃ for 4-6h to restore the printing quality of FusCoating^TM NexPA-CF25.

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。

It is recommended to use hardened steel and above grade nozzles made by Phaetus, which can effectively improve the print quality. Besides, it is recommended that the thickness of the heating block is longer 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FusCoating^TM NexPA-CF25打印件的强度，退火条件：80-100℃温度下放置4-8小时后取出即可。

After the printing is completed, the FusCoating^TM NexPA-CF25 printed part can be annealed to further improve the strength of print part. Annealing conditions: leave printing part in an oven at 80-100℃ for 4 to 8 hours and cool to room temperature naturally.
