Bambu Lab PA6-CF - Black (72100)
Bambu PA6-CF is a carbon fiber reinforced PA6 (Nylon 6) filament. The carbon fiber reinforcement provides significantly high stiffness and strength properties in dry environments and maintains exceptional heat resistance and impact resistance. Similar to other Bambu CF Filaments, these outstanding mechanical properties make it an ideal choice for printing fixtures, clamps, automotive and mechanical components and various structural and engineering parts that used in dry environments.
Superior Strength and Stiffness
As a new member of Bambu high performance filaments, PA6-CF keeps superior stiffness and strength properties in dry environments, it is perfect for printing load-bearing structural components.
Impact & Vibration Resistance
Bambu PA6-CF offers excellent impact resistance, ensuring effective vibration resistance for your prints. It is commonly used to print models that need to withstand impact, collision, and vibration.

Printing Tips
- Drying conditions: 80 °C for 10 hrs. PA6-CF is highly moisture-sensitive; dry before and after storage for best results.
- Absorbed moisture decreases strength and stiffness; damp models become tougher but less stiff—ideal for impact resistance.
- Remove support structures within 2 hours to avoid difficulty due to moisture softening.
- Dry and cool down prints if support becomes hard to remove.
- Apply waterproof coatings like paint or wax to prevent water absorption and maintain dimensional stability.
