Ultimaker PET CF Gray is a carbon-fiber-reinforced PET composite filament for the Ultimaker S-series printers. Combining PET's inherent chemical resistance with carbon fiber stiffness, it produces high-performance structural parts with a neutral gray finish that suits professional and industrial applications where a clean, technical appearance is important.

Gray is the most neutral and versatile color option in the Ultimaker PET CF range, suitable for customer-facing prototypes, technical assemblies and production components alike. It requires a CC print core for abrasion resistance from the carbon fiber reinforcement.

Key features

• Carbon fiber reinforcement delivers high stiffness and improved strength-to-weight ratio over standard PET-G.
• Inherent PET chemical resistance for industrial parts exposed to oils, fuels and cleaning agents.
• Neutral gray finish for professional and technical applications where appearance matters.
• 2.85 mm, 750 g spool compatible with Ultimaker S3, S5, S7 (requires CC print core).
• Also available in Black (art. 210000005142) and Blue (art. 210000005143); expansion kit (art. 210000005145) available.
