OzFDM PETG-CF Filament
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.

7 shades designed for performance and professional appeal.
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.
PETG-CF performs well through the AMS when handled with proper care and setup.
AMS Compatible, With Key Considerations
PETG-CF can be used with the Bambu Lab AMS, though extra care and setup considerations are essential to achieve the best results and maintain the integrity of your machine. The standard AMS is compatible, however, AMS Lite is not as its simplified design lacks the durability needed to withstand the rough and abrasive nature of PETG-CF. Due to the filament’s rigid carbon fibre content, continuous use may cause gradual wear on AMS components such as gears and PTFE tubes. To reduce wear, it is recommended to load PETG-CF into a less frequently used AMS slot to help distribute friction evenly across the internal feeding components and minimise the long term strain on gears and tubing. Or you could bypass the AMS machine completely by printing from a side mounted external spool holder, which provides a smoother filament path and removes any content within the AMS's moving parts all together.
Always dry the filament thoroughly before printing, ideally at 70°C for at least 5 hours, to maintain consistent quality and layer adhesion. Proper drying also helps prevent popping, uneven extrusion, and visible surface imperfections during long prints. Drying prevents moisture absorption that can cause bubbling, uneven extrusion, or a rough surface texture. Proper preparation helps PETG-CF retain its smooth flow and dimensional accuracy throughout longer prints When used with a hardened steel nozzle and correct cooling settings, PETG-CF performs smoothly while preserving the reliability of your printing hardware. A moderate fan speed is recommended to balance cooling and adhesion, while overcooling that 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.
