Fiberon ASA-CF08 Filament – 0.5 kg

Fiberon ASA-CF08 from Polymaker is a 1.75 mm ASA filament reinforced with 8% carbon fiber by weight. It pairs the UV and weather resistance of ASA with added rigidity, reduced warping, and a professional matte finish that hides layer lines. This listing is for a 0.5 kg spool.

Made for Outdoor and Functional Parts

ASA-CF08 is a strong choice for parts that live outside or near heat: outdoor fixtures and housings, automotive prototypes, marine and agricultural equipment, drone frames, jigs, and enclosures exposed to direct sunlight. With a heat deflection temperature of 103 °C at 0.45 MPa, it holds its shape where standard materials soften, and it reaches full performance straight off the printer with no annealing required.

Key Features

• 8% carbon fiber–reinforced ASA for higher stiffness
• UV and weather resistant for long-term outdoor use
• Heat deflection temperature of 103 °C at 0.45 MPa
• Matte surface finish that minimizes visible layer lines
• Low warping, with printing speeds up to 350 mm/s
• Prints reliably without a heated chamber
• Vacuum-sealed and tangle-free on a recycled cardboard spool

Printing Recommendations

Use a 0.4 mm or larger hardened steel or ruby nozzle, as the carbon fiber is abrasive and will wear brass quickly. An enclosed printer is recommended for consistent results, especially on tall or large prints, and printing should take place in a well-ventilated area because ASA releases odor and VOCs when heated. The filament is stiff and brittle, so keep its bending diameter above 60 mm while feeding, and use care with AMS and other multi-material systems. PolySupport for PA12 is recommended when supports are needed.
