Fiberon™ ASA-CF08 1.75mm 3D Printer Filament

Fiberon™ ASA-CF08 combines the proven UV and weather resistance of ASA with 8% carbon fiber reinforcement to produce strong, rigid, dimensionally stable parts designed for demanding environments. The carbon fiber reinforcement reduces warping while increasing stiffness, making ASA-CF08 an excellent choice for functional components that need to withstand outdoor exposure and elevated temperatures.

With a tensile strength of 43.5 MPa and bending strength of 69.1 MPa in the XY direction, ASA-CF08 provides the mechanical performance needed for durable fixtures, housings, brackets, jigs, and other functional components. Its 3265 MPa bending modulus provides a high level of rigidity while maintaining the inherent outdoor durability of ASA.

Key Benefits

• 8% carbon fiber reinforcement for increased rigidity and dimensional stability
• Excellent UV and weather resistance for outdoor applications
• High tensile and bending strength for functional components
• Heat deflection temperature up to 103°C at 0.45 MPa
• Reduced warping compared with conventional ASA
• Professional matte finish that helps conceal layer lines
• High-speed printing up to 350 mm/s
• Does not require a heated chamber
• Available in six professional colors
• No annealing required to achieve full performance

Typical Applications

• Outdoor fixtures and mounting hardware
• Protective housings and enclosures
• Automotive prototypes and components
• Marine and agricultural equipment
• Industrial jigs and fixtures
• Drone frames and structural components
• Functional prototypes
• Brackets, supports, and mechanical parts
• Components exposed to sunlight and elevated temperatures

ASA-CF08 is particularly well suited for applications where UV resistance, rigidity, dimensional stability, and heat resistance are more important than impact flexibility.

Because the carbon fiber reinforcement is abrasive, a hardened wear-resistant nozzle is essential. ASA-CF08 is also relatively brittle as a filament, so Polymaker recommends maintaining a bending diameter greater than 60mm during feeding.

Additional Information

ASA-CF08 is moisture-sensitive and should be stored and printed under dry conditions, ideally below 20% relative humidity. For the most consistent results, use an enclosed printer with appropriate ventilation and filtration. The material does not require a heated chamber or post-print annealing.

Due to its abrasive and brittle nature, caution is recommended when using ASA-CF08 with AMS and other multi-material feeding systems.
