Ultimaker PET CF Blue is a carbon-fiber-reinforced PET composite filament for the Ultimaker S-series printers. It combines PET's chemical resistance and dimensional stability with carbon fiber stiffness for high-performance structural parts. The blue color enables color-coded identification in multi-component assemblies, making it easy to distinguish PET CF Blue parts in inspection and production workflows.

Like all Ultimaker PET CF variants, this filament is well suited for functional end-use parts, brackets, housings and structural components requiring stiffness, low weight and resistance to industrial chemicals. Requires a CC print core.

Key features

• Carbon fiber reinforcement delivers high stiffness and improved strength-to-weight ratio over standard PET-G.
• Inherent PET chemical resistance for parts exposed to oils, fuels and cleaning agents.
• Blue color for color-coded component identification in assemblies and production workflows.
• 2.85 mm, 750 g spool compatible with Ultimaker S3, S5, S7 (requires CC print core).
• Also available in Black (art. 210000005142) and Gray (art. 210000005144); expansion kit (art. 210000005145) available.

Compatible with: Ultimaker S3, S5, S5R2, S7 (with CC print core)
