FusCoating™️ 一种共挤包覆结构的25%短切玻璃纤维增强ABS材料
产品简介
FusCoating™ NexABS-GF25是一款具有双层包覆结构的25%玻璃纤维增强ABS 3D打印线材。线材外层为高粘接强度的纯ABS树脂，线材内芯为25%短切玻璃纤维增强的ABS树脂。FusCoating™ NexABS-GF25 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。

其他建议： 1. FusCoating™ NexABS-GF25对比普通ABS-GF拥有更高的纤维含量，这种技术进一步提高了ABS材料的抗翘曲能力和刚性，因此可以适当降低环境温度以达到节能的目的。 2. 长期打开包装后的线材，如打印过程中发现气泡、拉丝等打印质量下降问题，请将线材置70℃条件下干燥4-6h。 3. 建议在打印ABS材料时将打印机放置在通风环境中。 4. FusCoating™ NexABS-GF25基于熔体稳定流动时处于层流状态的机理，材料在喷嘴挤出的细丝结构中依然能保持双层结构。但当打印速度过高时，熔体流动状态将变得不稳定，耗材在喷嘴挤出后的细丝将会破坏双层结构，最终导致打印件的表面质量变得粗糙。当出现此现象时建议提高打印温度或降低挤出速度。 5. 建议使用Phaetus硬化钢及以上等级耐磨喷头，可以有效提高打印质量，建议加热块厚度不小于12mm。
Additional Suggestions： 1. FusCoating™ NexABS-GF25 has a higher fiber content compared with ordinary ABS-GF. This technology further improves the warping resistance and rigidity of ABS materials, so the chamber temperature can be properly reduced to achieve energy saving. 2. If the filament has been opened for a long time and problems such as air bubbles and stringing appear during the printing process, please dry the filament at 70°C for 4-6 hours. 3. It is recommended to place the printer in a well-ventilated environment when printing with ABS material. 4. FusCoating™ NexABS-GF25 can maintain a core-skin structure when extruded from the nozzle. It is based on the mechanism that the melt polymer is in a laminar state when it flows stably, However, when the printing speed is too high, the melt flow state will become unstable, and the filaments extruded from the nozzle will no longer have the skin-core structure anymore, which can cause the rough surface of the printed part. When this phenomenon occurs, it is recommended to increase the printing temperature or reduce the extrusion speed. 5. It is recommended to use Phaetus hardened steel nozzles or nozzles with greater abrasion resistance, which can effectively improve the printing quality. The thickness of the heating block is recommended to be no less than 12mm. | |
