High-Speed Strength with Carbon Fiber Reinforcement

R3D High Speed Carbon Fiber PETG in Black is engineered for fast, reliable 3D printing without sacrificing strength or surface quality. Reinforced with carbon fiber, this PETG-based filament offers improved rigidity, dimensional stability, and a professional matte finish—making it ideal for functional parts and demanding applications.

Designed for modern high-speed printers, it delivers consistent extrusion and excellent layer bonding even at increased print speeds.

Key Features & Benefits

• Carbon Fiber Reinforced PETG
  Enhanced stiffness, reduced flex, and improved structural performance.
• High-Speed Printing Capability
  Optimized for faster print speeds without compromising print quality.
• Matte Black Finish
  Clean, professional look that helps hide layer lines and imperfections.
• Low Warping & High Stability
  Better dimensional accuracy compared to standard PETG.
• Improved Layer Adhesion
  Produces strong, durable parts with reliable bonding between layers.
• Reduced Stringing vs Standard PETG
  Cleaner prints with less post-processing required.

Typical Applications / Use Cases

• Functional mechanical parts and brackets
• Tooling, jigs, and fixtures
• Automotive and engineering components
• Robotics and drone parts
• Structural prototypes
• Enclosures and durable housings

Material & Compatibility

Carbon Fiber PETG combines the durability and flexibility of PETG with the stiffness of carbon fiber reinforcement.

Compatible with:

• Most 1.75mm FDM / FFF 3D printers
• High-speed printers (recommended for optimal performance)
• Enclosed and open-frame machines

Important considerations:

• Use a hardened steel or wear-resistant nozzle due to abrasive carbon fiber content
• Works best with stable extrusion systems and good cooling control

Printability & Performance

• Ease of Printing: Moderate difficulty; easier than many engineering filaments but requires proper setup
• Surface Finish: Matte texture that minimizes visible layer lines
• Strength Profile: High rigidity with reduced flexibility compared to standard PETG
• Bed Adhesion: Strong adhesion on PEI, textured plates, and glass with proper preparation
• Warping Behavior: Low warping, suitable for larger functional parts
• Speed Performance: Maintains quality at higher speeds compared to standard PETG

This filament is ideal for users looking to balance speed, strength, and surface quality in production-style workflows.

Why Users Choose Carbon Fiber PETG

Users choose R3D High Speed Carbon Fiber PETG for its ability to produce strong, dimensionally stable parts at faster speeds. The added carbon fiber reinforcement improves rigidity while the PETG base ensures durability and ease of printing compared to more advanced engineering materials.

The matte finish and reduced stringing make it especially appealing for functional parts that also need a clean, professional appearance.
