Polymaker Fiberon™ PA12-CF10 – Black – 500 g

It is suitable for machine components, automotive parts, production tools, jigs and fixtures, robotics, drones and functional prototypes. PA12-CF10 is particularly useful when a part must remain stiff and dimensionally stable under changing humidity.

The recommended nozzle temperature is 280–300°C, with a build plate at 40–50°C. Speeds of up to 300 mm/s are possible when the hotend can deliver the necessary volumetric flow. Reliable use requires a hotend capable of sustaining temperatures around 300°C.

No. Fiberon™ PA12-CF10 is designed for printing at room temperature without an actively heated chamber. Carbon fibres and Warp-Free™ technology limit shrinkage and improve dimensional stability. An enclosure can still help maintain consistent conditions for large parts.

Yes, when it has absorbed moisture. Polymaker recommends drying at 100°C for 10 hours and storing below 20% relative humidity. PA12-CF10 is considerably less moisture-sensitive than PA6-CF, but it remains a polyamide and gives the best results when dry.

Yes. Carbon fibres are highly abrasive, and Polymaker recommends hardened steel, ruby or another wear-resistant nozzle material. According to the technical data sheet, a standard brass nozzle may last around 9 hours with this filament, making it unsuitable for sustained use.

No. The recommended part cooling fan setting is 0%. This improves layer adhesion and reduces the risk of internal stress and delamination. For PA12-CF10, even cooling of the whole part is more important than strong local airflow.

Yes, when maximum mechanical and thermal properties are needed. Fiberon's current technical data sheet recommends annealing at 100°C for 16 hours. Small dimensional changes may occur during annealing, so this should be allowed for when designing parts with critical tolerances.
