OzFDM PPA-CF is a superior quality carbon fibre reinforced Polyphthalamide (Nylon) filament with excellent heat resistance of up to 220°C. Toughness and vibration resistance. It is made from 85% Nylon and 15% carbon fibre. For best results, anneal for 3 hours between 80 - 100°C after printing.

OzFDM’s PPA-CF brings together a high performance PPA base with finely milled carbon fibre to deliver serious strength, stiffness, and heat resistance, specifically designed for users who need engineering grade parts. PPA-CF offers excellent dimensional stability, low creep, and dependable layer adhesion so prints stay accurate even under sustained mechanical load. The reinforced matrix reduces warping and shrinkage compared with standard nylons, making it easier to achieve clean, predictable results with sharper edges, tighter tolerances, and less print variation, even on demanding structural parts.

A reliable and consistently performing filament, developed for functional components and real world assemblies, PPA-CF stands up to elevated temperatures, repeated stress, harsh environments, it resists many oils and chemicals, holds threads well, and maintains rigidity where other materials may soften or deform. Whether you are building brackets, drone or automotive parts, or production ready fixtures, PPA-CF delivers a refined technical finish and performance that earns its place in demanding applications, producing parts that look sharp, feel solid, and continue to perform long after installation.

Carbon Fibre Black - PPA-CF

PPA-CF is available in a single, purpose built Carbon Fibre Black shade that reflects its engineering focus. The dark, slightly textured surface hides wear, fingerprints, and minor artefacts while emphasising the material’s structural character. This carbon rich finish masks layer lines, photographs cleanly, and pairs well with both vibrant and industrial colour palettes used elsewhere in your build.

Choose Carbon Fibre Black when you want parts that look serious, technical, and ready for work straight from the print bed.

Feed PPA-CF from an external dry box.

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 PPA-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.

PPA-CF is sensitive to moisture and prints at elevated temperatures, so dry it thoroughly and feed it from a heated dry box rather than storing it loaded for long periods. A hardened nozzle and a printer rated for its recommended print temperatures are required.

Performance Refined for Real World Printing

Built for High Demand Projects

PPA-CF is engineered for critical components where failure is not an option, its excellent tensile strength, stiffness, and fatigue resistance for brackets, arms, housings, and fixtures that experience real, everyday load.

It features significantly lower moisture absorption than standard nylon, maintaining dimensional stability while delivering impressive wear and creep resistance for parts exposed to friction and long term stress.

The carbon fibre reinforcement supports the filament under bending and torsion, helping parts retain form and accuracy through repeated use.

Together, these properties give you a filament that maintains structural integrity and dependable performance even in demanding environments.

Stable, Accurate and Consistent

The semi aromatic PPA base gives PPA-CF a naturally stable foundation, helping it hold its shape far more reliably than many traditional nylon blends. This unique feature sets PPA-CF apart from other nylon blends in terms of structural integrity and durability.

With reduced shrinkage and noticeably lower warping, prints come off the bed with cleaner lines, truer dimensions, and reliably formed openings.

This stability allows interference fits, bearing seats, and threaded inserts to align exactly as intended, minimising post processing and improving overall part accuracy.

By delivering predictable results across both simple and complex geometries, PPA-CF lets you design with confidence and push tolerances further without compromising reliability.

Ready for Heat, Stress and Motion

With elevated heat resistance and strong interlayer bonding, PPA-CF is comfortable in environments where PETG or PLA based materials may soften or creep. It stays firm in warm enclosures, around motors, and in fixtures that see repeated motion or clamping pressure.

PPA-CF is a reliable choice for those looking for a filament that can withstand high temperatures and maintain its structural integrity in demanding environments.

For makers and engineers who need a filament that can move from prototype to production ready parts, PPA-CF offers a confident blend of strength, stability, and long term reliability.

Technical Specifications

Product Specifications

Each spool of OzFDM’s premium PPA-CF filament is securely vacuum sealed with a moisture absorbing desiccant to maintain optimal print quality right up to that special moment you open the box.

Every package includes recommended printing and drying settings, ensuring you achieve smooth, consistent results right from your first layer.
