SUNLU PA12-CF Black – Carbon fiber reinforced PA12 filament for the highest demands

SUNLU PA12-CF Black is a high-performance 3D printing filament that combines the robustness of polyamide 12 (PA12) with the high strength of carbon fiber. This material offers excellent mechanical properties, including heat resistance up to 176°C , very good impact resistance, and low moisture absorption. This makes it ideal for demanding projects requiring precision, stability, and durability.

Advantages and features

• Carbon fiber reinforced for maximum strength

• Heat resistant up to 176 °C

• Excellent impact and abrasion resistance

• Low moisture absorption for high dimensional stability

• Lightweight material with excellent strength-to-weight ratio

• Suitable for wear-resistant nozzles (e.g. hardened steel)

Possible applications

SUNLU PA12-CF Black is ideal for functional prototypes and final components that must withstand high mechanical stress. Typical applications include the automotive industry , the aerospace sector , industrial tools , and outdoor equipment . This filament impresses with its stability, even for components exposed to extreme temperatures or harsh environments.

Printing instructions

For optimal results, a printing temperature of 260–280 °C and a print bed temperature of 60–70 °C are recommended. The ideal printing speed is between 60 and 100 mm/s. A suitable adhesive (e.g., PVA or Magigoo PA) can be used to improve adhesion.
Since the filament contains carbon fibers , abrasion-resistant nozzles should be used to prevent premature wear.
Before printing, it is recommended to dry the filament at 80°C for 12 hours or at 110°C for 4 hours. Storing it in a dry environment will maintain long-term quality.
