Description
Engineered Strength Meets Everyday Printability
PETG-CF Carbon Fiber combines the chemical resistance and toughness of PETG with 16% chopped carbon fibre reinforcement, delivering a filament that prints almost as easily as standard PETG but produces parts with noticeably higher stiffness and reduced warping. The carbon fibre content improves dimensional stability during cooling, making it well suited to larger prints and parts with tight tolerances.
The result is a filament that bridges the gap between basic PETG and full engineering-grade composites — without the extreme temperatures or enclosed chamber requirements of materials like polycarbonate or nylon carbon fibre.
Why Choose Carbon Fiber PETG?
Contains 16% chopped carbon fibre for increased rigidity and stiffness
Reduced warping and improved dimensional accuracy on larger prints
Professional matte surface finish that hides layer lines
UV stable — suitable for outdoor and semi-structural applications
Excellent chemical resistance inherited from the PETG base
Lower moisture sensitivity than nylon-based carbon fibre filaments
Prints at standard PETG temperatures with no heated chamber required
High strength and impact resistant while remaining beginner friendly
Ideal Applications
Carbon Fiber PETG is the go-to filament when standard PETG isn’t rigid enough but you don’t need the full performance envelope of PA-CF or PC-CF. Common applications include drone frames, camera mounts, tool holders, jigs and fixtures, enclosure panels, automotive interior parts, and functional prototypes that need to hold their shape under moderate load.
Hardened Steel Nozzle Highly Recommended
Carbon fibre is abrasive and will rapidly wear a standard brass nozzle. A hardened steel extruder and nozzle are highly recommended. We suggest a 0.4 mm or larger nozzle diameter for best results — a 0.6 mm nozzle can further reduce the chance of partial clogs from fibre bundles.
