FusCoating™️ NexABS-CF20 is one type 3D printing ABS filament with co-extrusion skin-core structure and 20% Carbon fiber to improve its mechanical properties.
Product Description
FusCoating™ NexABS-CF20 is a carbon fiber reinforced ABS material with a skin-core structure. The inner core is ABS reinforced with 20% chopped carbon fiber, and the outer shell is unfilled ABS resin with high bond strength.
The polymer fluid is always in a laminar flow state in the throat and nozzle so the skin-core structure of filaments can be maintained even after being extruded through the nozzle. This skincore structure not only contributes to the low shrinkage, warpage resistance and excellent mechanical properties which ordinary fiber-reinforced materials have, but stronger interlayer bonding performance for printed parts as well. It has fixed the defect that the ordinary fiberreinforced material will lose the bonding strength between layers. Meanwhile, there is no floating fiber on the surface of the printed part, and the surface presents a bright matte texture.

Printing Tips：
- FusCoating™ NexABS-CF20 has a higher fiber content compared with ordinary ABS-GF/CF. This technology further improves the warping resistance and rigidity of ABS materials, so the chamber temperature can be properly reduced to achieve energy saving.
- 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 60-70°C for 4-6 hours.
- It is recommended to place the printer in a well-ventilated environment when printing with ABS material.
- FusCoating™ NexABS-CF25 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.
- 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.
