Black - Bambu Lab PETG-CF Filament - 1.75mm,1kg

Carbon Fiber PETG for Strong, Clean, and Reliable Prints

Bambu Lab PETG-CF Filament in Black combines the ease of PETG with the strength and stiffness of carbon fiber reinforcement. Designed for users who need durable, functional parts without the complexity of nylon-based materials, PETG-CF offers an excellent balance of printability, mechanical performance, and surface quality.

With improved rigidity over standard PETG and a signature matte finish, this filament is ideal for functional prototypes, end-use parts, and professional applications.

Key Features & Benefits

• Carbon Fiber Reinforced Strength
  Increased stiffness and structural integrity compared to standard PETG.
• Easy-to-Print Engineering Material
  More forgiving than nylon composites while still offering enhanced performance.
• Low Warping and Good Dimensional Stability
  Ideal for consistent, accurate prints without enclosure requirements in many cases.
• Matte Black Surface Finish
  Produces clean, professional-looking parts with reduced visible layer lines.
• Improved Layer Adhesion
  Strong interlayer bonding for reliable functional components.
• Balanced Durability and Flexibility
  More rigid than PETG, but less brittle than PLA-based composites.

Typical Applications

• Functional prototypes and end-use parts
• Tooling, jigs, and fixtures
• Enclosures and structural components
• Robotics and mechanical assemblies
• RC parts and lightweight structures
• Brackets, mounts, and housings
• General-purpose engineering prints

PETG-CF is widely used when strength, ease of use, and visual quality are all important.

Material & Compatibility

Bambu Lab PETG-CF is compatible with most 1.75mm FDM 3D printers and is easier to print than many carbon fiber nylon materials.

Printing Characteristics:

• Semi-rigid material with added stiffness
• Low warping compared to ABS and nylon
• Smooth extrusion with reduced stringing when tuned
• Matte surface finish with subtle carbon fiber texture

Printing Considerations:

• Hardened steel nozzle recommended due to abrasive carbon fiber
• Heated bed improves adhesion
• Moderate cooling helps balance surface quality and layer strength
• Enclosure optional but beneficial for larger parts

Compatible with:

• Bambu Lab X1 and P1 Series (with hardened nozzle recommended)
• Prusa, Creality, Anycubic, and most 1.75mm FDM printers

Why Users Choose Bambu Lab PETG-CF
