Bambu Lab PA6-CF Black
Bambu Lab PA6-CF Black
Bambu PA6-CF is a carbon fiber reinforced PA6 (Nylon 6) filament. Carbon fiber reinforcement provides significantly higher stiffness and strength properties in dry environments, while maintaining excellent heat resistance and impact resistance. Similar to other Bambu CF filaments, these excellent mechanical properties make it ideal for printing jigs, fixtures, automotive and mechanical parts, and various structural and engineering components for use in dry environments.
Excellent Strength and Stiffness
As a new member of Bambu's high-performance filaments, PA6-CF maintains excellent stiffness and strength properties in dry environments, making it ideal for printing load-bearing structural parts.
| Normal PA-CF | PA6-CF | Improvement % | |
| Strength (Flexural Strength - XY, Dry State) | 128MPa | 151MPa | 18% |
| Stiffness (Flexural Modulus - XY, Dry State) | 4420MPa | 5460MPa | 24% |
Bambu PA6-CF features excellent impact resistance, ensuring your prints effectively resist vibration. It is often used for printing models that need to withstand impacts, collisions, and vibrations.
* If PA6-CF is left in a humid environment for more than 1 day, the printed part will harden.
