Ventajas del producto
Co-extrusion ‘skin-core’ structure
FusRock® is a new generation of industrial 3D printing filament with a skin-core structure by using multi-layer co-extrusion technology. The outer ‘skin’ of the filament is a modified resin with high layer adhesion, and the inner core is reinforced resin containing high chopped fiber content. The co-extrusion skin-core technology has greatly increased fiber content while maintaining the toughness of the filament and thus improved the mechanical properties as well as heat resistance of printed parts.
Excellent layer adhesion
FusCoating™ 3D printing filaments have taken advantage of the laminar flow of polymeric fluids during the extrusion process and maintain the stable skin-core structure even after the filament passes through the nozzle of the printer. Among many other fiber-reinforced filaments, Z-axis layer adhesion loss is always a common issue during printing. However, for FusCoating™ 3D printing filaments, the interlayer adhesion in Z-axis comes from the adhesion between the resin of the outer shell and this can completely avoid the layer adhesion loss caused by the fibers added. In addition, after being extruded through the nozzle, the inner core and outer layer of the filament are heated, melted and bonded together again. In this way, the adhesion between the core and skin can reach the optimal level and the fibers of the inner core can effectively withstand the force from outer layer resin in Z-axis. With these advantages, the Z-axis interlayer adhesion of the parts printed with FusCoating™ is further improved compared with those printed with pure resin filaments.
Reducing nozzle abrasive wear
During the extrusion process, the FusCoating™ can greatly reduce the wear of the nozzle. The material that slides against the inner wall of the nozzle is made of pure resin, which greatly limits the contact between the reinforcing fibers and the nozzle. At the same time, the skin-core structured filament can also help to avoid contact between the reinforcing fibers of the filament and extruders or throats, which prolongs the service life of the entire extrusion parts of the 3D printer.
Odorless
The main raw material of FusCoating™ NexABS-CF20 is an ABS resin synthesized by continuous bulk polymerization technique. Thanks to this advanced production process, the residual amount of solvents and monomers used in the production process in the final ABS product is so low that the filament has a low odor during printing.

- 1. 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.
- 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 60-70°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-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.
- 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.
