Bambu Lab PA6-CF Filament 1.75mm 500g – Carbon Fiber Reinforced Nylon for Engineering Parts
Bambu Lab PA6-CF is a premium carbon fiber reinforced nylon filament designed for high-performance engineering applications. This PA6 carbon fiber filament combines the strength of PA6 (Nylon 6) with carbon fiber reinforcement to deliver exceptional stiffness, strength, and heat resistance.
With 18% higher bending strength and 24% higher bending modulus compared to standard PA-CF, Bambu PA6-CF is ideal for structural parts, fixtures, jigs, and mechanical components that demand superior mechanical properties in dry environments.
Bambu Lab PA6-CF Key Features
- Exceptional Strength – Tensile strength of 102 MPa, bending strength of 151 MPa
- High Stiffness – Flexural modulus of 5460 MPa for rigid, precise parts
- Superior Heat Resistance – Maintains properties at elevated temperatures
- High Impact Resistance – Impact strength of 40.3 kJ/m² for durable parts
- Lightweight – Carbon fiber reduces weight while increasing strength
- RFID Enabled – Works with Bambu Lab AMS for automatic settings

Test conditions per Bambu Lab TDS V3.0. Specimens annealed and dried at 80°C for 12h before testing. XY orientation (dry state).
Important: Moisture Sensitivity
PA6-CF is highly moisture-sensitive. This filament will absorb water from the air, which significantly reduces strength and stiffness. Always:

PA6-CF Filament Applications
- Engineering Fixtures – Jigs, clamps, and assembly fixtures
- Automotive Components – Structural parts, brackets, mounts
- Mechanical Parts – Gears, levers, structural components
- Industrial Tooling – End-of-arm tooling, robot grippers
- Drone Components – Lightweight, stiff frames and mounts
- Prototypes – Functional prototypes requiring high strength
PA6-CF Printing Tips
- Drying is Critical – Dry at 80°C for 10+ hours; wet filament causes bubbles and weak parts.
- Use Hardened Nozzle – 0.6mm+ hardened steel required; brass wears quickly.
- Enclosure Required – Needs 40-60°C chamber to prevent warping.
- Consider Annealing – 80-130°C for 6-12 hours for max strength.
- Avoid Humidity – Parts absorb moisture; not for outdoor use.

Bambu Lab PA6-CF FAQ
Q: What printer do I need for PA6-CF?
A: You need an enclosed printer with high-temperature capability (270-290°C nozzle), heated bed (80-100°C), and a hardened steel nozzle. Bambu Lab X1C, P1S, and similar enclosed printers work well.
Q: Can I use a brass nozzle with PA6-CF?
A: No. Carbon fiber is extremely abrasive and will destroy a brass nozzle within hours. Use hardened steel, ruby, or tungsten carbide nozzles only.
Q: How does PA6-CF compare to PETG-CF or PLA-CF?
A: PA6-CF is significantly stronger and stiffer than PETG-CF or PLA-CF, with much better heat resistance. However, it requires an enclosed printer, careful drying, and is moisture-sensitive in use.
Q: Why are my PA6-CF prints weak or brittle?
A: Most likely the filament absorbed moisture. PA6 is extremely hygroscopic. Dry at 80°C for 10+ hours and print immediately. Wet PA6-CF will be brittle with visible bubbles.
Q: Can I use PA6-CF for outdoor applications?
A: Not recommended. PA6-CF absorbs moisture from humidity, which reduces its mechanical properties over time. For outdoor use, consider ASA or ASA-CF instead.
