Bambu Lab PA6-CF Black
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 while maintaining excellent heat resistance and impact resistance. Similar to other Bambu CF filaments, these superior mechanical properties make it ideal for printing fixtures, jigs, automotive and mechanical parts, and a variety of structural and engineering components used in dry environments.
Exceptional strength and stiffness
As a new member of Bambu's high-performance wire family, PA6-CF maintains excellent stiffness and strength even in dry environments, making it ideal for printing load-bearing structural components.
| Normal PA-CF | PA6-CF | improve% | |
| Strength (flexural strength - XY, dry state) | 128MPa | 151MPa | 18% |
| Stiffness (flexural modulus - XY, dry state) | 4420MPa | 5460MPa | twenty four% |
Impact and vibration resistance
Bambu PA6-CF offers excellent shock resistance, ensuring your prints are effectively protected against vibration. It is typically used for printing models that need to withstand impacts, collisions, and vibrations.
* Prints from PA6-CF will harden if left in a humid environment for more than one day.
