BambuLab PET-CF Black (71100) with Spool, 0.5kg

Introducing the BambuLab PET-CF Black filament, a high-performance carbon fiber reinforced PET material designed for demanding engineering applications. This 0.5kg spool delivers exceptional strength, stiffness, and dimensional stability, making it ideal for functional prototypes, jigs, fixtures, and drone frames. The black color provides a professional finish, while the 1.75mm diameter ensures compatibility with a wide range of FDM printers, including Bambu Lab X1 Series, P1P, P1S, A1 Series, and others.

Advantages

PET-CF combines the toughness of PET with the rigidity of carbon fiber, resulting in parts that are both strong and lightweight. The 15% carbon fiber content significantly increases flexural modulus and tensile strength, reducing warping and improving layer adhesion. This filament is moisture-sensitive, so proper drying is recommended for optimal print quality. With a recommended nozzle temperature of 260-280°C and bed temperature of 80-100°C, it prints reliably on hardened steel nozzles (0.4mm or larger).

Suitable for

• Engineering parts and functional prototypes
• Jigs, fixtures, and tooling
• Drone frames and lightweight structural components
• Automotive and industrial applications requiring high strength-to-weight ratio
• Replacement for metal parts in non-critical applications

Recommendations

For best results, dry the filament at 65°C for 8 hours before printing. Use a hardened steel nozzle to prevent wear from carbon fiber. Ensure your printer is enclosed to maintain stable temperatures and reduce warping. Store in a dry environment to preserve filament quality.
