Carbon - Spectrum Carbon PET-G Filament - 1.75mm, 1kg

Carbon PETG 1kg – Strong, Durable, and Built for Demanding Prints

Spectrum Carbon PETG Filament is designed for users who need durable, functional parts with a professional finish. Combining PETG’s toughness with carbon fiber reinforcement, this material delivers increased stiffness, improved dimensional stability, and excellent resistance to wear and environmental conditions.

With a full 1kg spool, it’s ideal for extended print jobs, batch production, and engineering workflows where performance and reliability are essential.

Key Features & Benefits

• Carbon Fiber Reinforced PETG
  Increased rigidity and strength compared to standard PETG
• Matte, Professional Finish
  Produces a clean, low-gloss surface that minimizes visible layer lines
• High Impact Resistance
  More durable than PLA, suitable for functional and real-world applications
• Excellent Dimensional Stability
  Reduced warping and shrinkage for accurate, repeatable parts
• Moisture & Chemical Resistance
  Suitable for outdoor use and demanding environments
• 1kg Spool for High-Volume Printing
  Ideal for print farms, prototyping, and production runs

Typical Applications

• Functional mechanical components
• Outdoor parts and enclosures
• Jigs, fixtures, and tooling
• Automotive and workshop accessories
• Robotics and drone parts
• Structural and load-bearing prototypes

Material & Compatibility

Spectrum Carbon PETG is compatible with most FDM/FFF 3D printers that support 1.75mm filament and PETG materials.

• Works with open filament systems such as Prusa, Creality, Bambu Lab, and similar platforms
• Compatible with PEI, glass, and textured build surfaces
• Suitable for printers with stable temperature control and adequate cooling

Important Usage Notes:

• Carbon fibers are abrasive — a hardened steel nozzle is strongly recommended
• Heated bed improves adhesion and reduces print failure risk
• Moderate cooling helps maintain strength and surface quality
• Slightly slower speeds improve layer bonding and finish

Printability & Performance

• Ease of Printing: Moderate – more demanding than PLA, easier than advanced engineering materials
• Surface Finish: Matte, slightly textured, professional appearance
• Strength Profile: Strong, rigid, and impact-resistant
• Warping: Low to moderate, manageable with proper settings
• Layer Adhesion: Excellent when printed within recommended temperature ranges

Why Users Choose Spectrum Carbon PETG
