Fiberon™ PA6-CF20 is a high-performance engineering filament based on polyamide 6 (PA6) reinforced with 20% carbon fibers. It combines the exceptional strength, stiffness and thermal resistance of polyamide with the reinforcing effect of carbon fibers, making it an ideal material for functional parts, prototypes and replacement components with high mechanical requirements.

Key features

Carbon fibers in the nylon PA6 matrix ensure high dimensional stability, minimal deformation under load and significantly higher stiffness compared to standard materials. The filament offers excellent thermal resistance, good chemical resistance to oils and solvents, and low surface friction of the print. The carbon filling also suppresses the shrinkage typical of pure PA6, which makes printing larger parts easier. The material is hygroscopic - it must be properly dried before printing.

Printing parameters

Who is Fiberon™ PA6-CF20 filament, 500g suitable for

The material is intended for advanced users and professionals who need parts subjected to long-term mechanical and thermal stress. Typical applications include machine components, gears, brackets, structural elements of drones and RC models, industrial tools, jigs and fixtures, electronics enclosures or functional prototypes with high stiffness requirements. Thanks to the carbon filling, it is also suitable for parts where low weight combined with strength is important.

Printing tips

• Always dry the filament immediately before printing - PA6 quickly absorbs moisture from the air and insufficiently dried material leads to cracking, bubbles and reduced strength.
• Use a wear-resistant nozzle (hardened steel, ruby or diamond) - carbon fibers will quickly damage a standard brass nozzle.
• We recommend printing in an enclosed chamber to suppress warping and delamination between layers.
• For better first-layer adhesion, use an adhesive such as Magigoo PA, PVA glue or a special PA print surface.
• A higher nozzle temperature (around 290-300 °C) improves interlayer strength.
• Reduce print speed for thin-walled parts and fine details to achieve a cleaner surface.
• Store in a dry environment with silica gel or in an active dry box.
