FusRock NexPA-CF25 25% carbon fiber content and a skin-core structure.

 

Product Description

FusCoating™ NexPA-CF25 is an outstanding candidate for printing parts that need to have thin walls and high mechanical property requirements. It is one type of 3D printing filament with 25% carbon fiber content and a skin-core structure. The outer ‘skin’ of the filament is a modified resin with high layer adhesion strength, and the inner core is reinforced resin containing high chopped fiber content. FusCoating™ 3D printing filaments take advantage of the general laminar flow of polymeric fluids during extrusion and maintain the stable skin-core structure even after the filament passes through the nozzle of the printer. This technology contributes to the excellent Z-axis interlayer adhesion of FDM fiber-reinforced filaments because the major layer adhesion comes from the outer shell rein without fibers. Meanwhile, 25% chopped cabron fiber content can improve the mechanical properties and heat resistance of the printed parts.

Printing Tips:

1. Nylon material is very easy to absorb moisture within the environment, and printing after absorbing moisture will result ozzing, extruding with bubbles and rough surface appearance, thus reducing print quality. It is recommended that put the filament into a dry box (humidity below 15%) immediately after opening the FusCoatingTM NexPA-CF25 vacuum foil bag for printing. Please put the unused filament back into the original aluminum foil bag for sealed storage.

2. After the material is damp, there will be more printing ozzing, bubbles extruded and roughprinting surface. Please dry the filament in an oven at 80-100℃ for 4-6h to restore the printing

quality of FusCoatingTM NexPA-CF25.

3. It is recommended to use hardened steel and above grade nozzles made by Phaetus, which can effectively improve the print quality. Besides, it is recommended that the thickness of the

heating block is longer 12mm.

4. After the printing is completed, the FusCoatingTM NexPA-CF25 printed part can be annealed to further improve the strength of print part. Annealing conditions: leave printing part in an oven

at 80-100℃ for 4 to 8 hours and cool to room temperature naturally.
