aaeCoatingTM NexABS-GF25 is one type 3D printing ABS filament with co-extrusion skin-core structure and 25% glass fiber to improve its mechanical properties.
Phaetus aeCoatingTM NexABS-GF25 is a glass fiber reinforced ABS material with a skin-core structure. The inner core is ABS reinforced with 25% chopped glass 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 skin-core 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 fiber-rein- forced 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.
- Co-extrusion ‘skin-core’ structure
aeCoating® 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
aeCoatingTM 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 aeCoatingTM 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 aeCoatingTM is further improved compared with those printed with pure resin filaments.
- Reducing nozzle abrasive wear
During the extrusion process, the aeCoatingTM 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.
