OzFDM PETG-CF filament is an advanced 3D printing material, offering superior strength and resistance due to its carbon fibre reinforcement. This 1.75mm filament has a diameter tolerance of ± 0.05mm, and comes in a 1KG spool for long-term use. It's the perfect choice for engineering, automotive, and other industrial applications.

OzFDM's PETG-CF (Polyethylene Terephthalate Glycol + Carbon Fibre) filament combines the toughness and reliability of PETG with the added rigidity, heat resistance, and dimensional stability of carbon fibre reinforcement. The finely chopped fibres increase overall strength while reducing shrinkage, warping, and surface imperfections, resulting in prints that are both durable and visually refined. This advanced blend maintains PETG's signature toughness and chemical resistance while delivering a clean, professional matte finish with a subtle grain texture that highlights the carbon fibres within each layer, giving printed parts a sleek, technical appearance and a premium feel that reflects both strength and precision. PETG-CF performs exceptionally well for functional prototypes, mechanical parts, drone components, and production ready models that demand high impact strength and thermal stability. When paired with a hardened steel nozzle, it offers consistent performance, reliable adhesion, and premium results across a wide range of technical applications.

PETG-CF Colour Range

PETG-CF is available in 7 shades that highlight the fine texture of its embedded fibres. The matte finish provides a sleek, engineered appearance that feels professional and understated, while each tone subtly enhances the grain detail created by the carbon fibre blend.

This refined surface not only improves the aesthetic of functional prints but also helps mask layer lines and minor imperfections. The result is a filament that delivers both durability and visual balance, ideal for mechanical parts, tools, and production components that need to look as strong as they perform.

Feed PETG-CF from an external spool holder.

Not Recommended for the Bambu Lab AMS

Bambu Lab advises against running third party fibre filled filament through the AMS. Its own filament guide warns that some brands of carbon and glass fibre filament are "too hard and rough, which can easily damage the AMS / AMS lite channel", and that others are "too brittle and prone to break" inside it. Where the AMS is listed as supported for a fibre filled material, that entry refers to Bambu Lab’s own spools, not to third party filament.

Feed PETG-CF from an external spool holder or a sealed dry box straight into the printer instead. The shorter, straighter filament path keeps the abrasive fibres away from the AMS gears, PTFE tubing and funnel, lowers feed resistance and gives steadier extrusion on long prints. A hardened steel nozzle is still required.

Always dry the filament thoroughly before printing, ideally at 70°C for at least 5 hours, to maintain consistent quality and layer adhesion. Drying prevents the popping, uneven extrusion and rough surface texture that absorbed moisture causes. Use a hardened steel nozzle and a moderate fan speed to balance cooling and adhesion, as overcooling can weaken layer bonding or cause delamination on larger models.

Performance Reinforced, PETG-CF Filament

Precision Reinforced

PETG-CF combines the reliability of PETG with the stiffness and dimensional stability of carbon fibre reinforcement. The result is a filament that delivers higher strength, improved temperature resistance, and enhanced layer consistency while maintaining PETG's signature toughness and ease of use.

The carbon fibre particles increase rigidity throughout each layer, allowing printed parts to resist flexing, deformation, and surface distortion even under mechanical load or elevated heat.

It prints with low shrinkage and minimal warping, making it ideal for precise, functional components that need to perform under pressure and need to maintain dimensional accuracy over time.

The surface finish has a subtle matte texture that adds a refined, technical look to every print, offering both the visual appeal and performance reliability expected from professional grade materials.

Performance You Can Trust

The addition of carbon fibre gives PETG-CF exceptional rigidity and mechanical endurance, allowing parts to hold their form under load and heat. This reinforcement enhances structural stability across complex geometries, reducing flex and deformation even during prolonged mechanical stress or elevated temperatures.

The carbon fibre also distributes internal forces more evenly, giving printed parts a balanced strength that rivals many engineering grade materials while maintaining PETG’s reliability and print consistency.

Its enhanced layer adhesion and stable flow reduce the chance of warping or deformation, even in larger prints. This combination of strength and consistency makes PETG-CF perfect for tools, jigs, brackets, and mechanical housings that need long-term reliability.

While slightly more advanced to print than standard PETG, it rewards careful setup with worthwhile results that remain stable across demanding applications.

Built for Real World Projects

From replacement components and structural prototypes to drone frames, racing models, and protective enclosures, PETG-CF is built for projects where durability meets design precision.

Its advanced blend of high stiffness, impact strength, and thermal resistance allows it to perform consistently in demanding environments where standard PETG may soften, flex, or lose structural integrity under heat.

The finely dispersed carbon fibres reinforce each layer, providing greater stability and resistance to fatigue, even in parts subject to vibration or continuous load. The matte, carbon-infused surface delivers a clean, technical aesthetic that masks layer lines, enhances surface quality, and reduces the need for post processing.

For makers and engineers seeking dependable, production ready results, PETG-CF delivers the ideal combination of strength, precision, and visual refinement, a material engineered to look professional and perform flawlessly over time.

Good Product

Good Service, Easy Print

Thank you very much for taking the time to leave a review. We are very glad you had a great experience with our filament.

Shockingly good

Magic stuff, and local! Win win

Life-changing. That’s not an exaggeration!

I loaded up the OzFDM PETG-CF filament, hit print, and braced for the usual 3D printing drama—stringing, warping, adhesion tantrums. But no. This filament printed like it had something to prove. The layers fused together like best friends at a high school reunion, the surface finish looked so premium I considered charging myself extra, and the strength? Let’s just say I trust this stuff more than some of my own decisions.

No clogs, no adhesion issues, just pure 3D printing magic. I’ve already ordered more because I refuse to go back to a life without it. 11/10, would hoard in case of an apocalypse.

Looks and prints well :)

Made sure to dry at 70c for 5hrs and then printed out some printer mods and some functional prints and they look awesome, nice and stiff but have good flex. Keen to see what else I can apply this filament to :)
