NexASA-GF25 is a 25% glass fiber reinforced ASA filament with a skin-core structure. The inner core is ASA reinforced with 25% chopped glass fiber, and the outer shell is unfilled ASA resin with high bond strength. The polymer fluid maintains laminar flow in the throat and nozzle so the skin-core structure is preserved after extrusion. Interlayer bonding along the Z axis stays in the pure resin shell, while the glass fiber reinforcement improves overall mechanical performance and weather resistance for thin-wall and high-performance parts.
製品の強み
Co-extrusion ‘skin-core’ structure
FusRock® invented a new generation of industrial 3D printing filament with a skin-core structurer 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 and heat resistance of the printed parts.
Excellent layer adhesion
FusCoating™ 3D printing filaments have taken advantage of the general laminar flow of polymeric fluids during the extrusion 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 Z-axis interlayer adhesion comes from the adhesion between the resin of the outer shell and this can completely avoid the layer adhesion loss. In addition, after being extruded through the nozzle, the inner core and outer layers of the extruded filament are heated, melted and bonded together again. In this way, the adhesion between the inner and outer layers can reach the optimal level and the fibers of the inner core can effectively withstand the force from the z-axis outer layer resin. With these two advantages, the Z-axis interlayer adhesion of final parts printed with FusCoating™ is further improved compared to parts 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 contacts 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 avoid the 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.
