3D printing filament Azurefilm FG171-CABK — Carbon fibre reinforced PET (PET) 1.75 mm, 500 g, Black

Azurefilm FG171-CABK is a 1.75 mm carbon-fibre reinforced PET filament designed for FDM 3D printing. Supplied on a 500 g spool in black, this PET CF material combines PET base polymer properties with chopped carbon fibre reinforcement to increase stiffness, surface hardness and z-layer strength compared with standard PET. The filament is manufactured in the EU and formulated to reduce common printing issues such as stringing, warping and clogging when used with appropriate hardware and nozzle size.

Advantages

The chopped carbon fibre composite provides improved impact toughness and elevated mechanical performance while maintaining low water uptake and minimal warping. With 15% carbon fibre content and a short-term maximum temperature resistance up to 125°C (able to sustain 100°C for extended periods), the material is suitable for functional prototypes, mechanical parts and tools that require higher rigidity and surface hardness. The formulation aims for reliable extrusion and clean surface finish on compatible printers.

Suitable for

• Functional prototypes and mechanical test parts
• End-use components, brackets and housings requiring stiffness
• Tools, jigs and fixtures for workshop or industrial use
• Applications where improved z-layer strength and low warping are required

Key specifications

• Filament diameter: 1.75 mm
• Spool weight: 500 g
• Base material: Polyethylene terephthalate (PET) with carbon fibre reinforcement (15% by weight)
• Colour: Black
• Fibre length (chopped): approximately 0.4–0.6 mm
• Short-term maximum service temperature: up to 125°C (max ~3 hours)
• Extended use temperature: can sustain 100°C for 10 hours or more
• Recommended nozzle diameter: 0.6 mm or larger due to fibre content
• Low moisture uptake and reduced tendency to warp

How to use

Use this filament in FDM printers that support 1.75 mm filament and are compatible with abrasive or fibre-reinforced materials. Install a hardened steel or wear-resistant nozzle of 0.6 mm diameter or larger to prevent nozzle wear and to allow passage of chopped fibres. Prepare the filament spool on a dry, stable mount and dry the filament if necessary according to your printer’s drying procedure before printing. Typical printing settings should follow PET-based material profiles: adjust nozzle temperature, print speed, layer height and bed temperature to achieve consistent extrusion and bonding. Monitor initial layers to ensure good bed adhesion and adjust flow or first layer settings as needed.

Usage recommendations

To prolong nozzle life and ensure consistent results, use a hardened nozzle and avoid fine-diameter nozzles below 0.6 mm. Store the filament in a dry environment or sealed container with desiccant to maintain low moisture content. When optimizing mechanical performance, vary infill density, print orientation, layer thickness and printing speed — these parameters influence final strength and surface quality. For industrial use, verify compatibility with your printer and test critical parts before full production runs.
