Filament BambuLab PA6-CF 1.75 mm 1 kg with reusable spool — Black

BambuLab PA6-CF 1.75 mm 1 kg with reusable spool — Black is a carbon-fiber–reinforced PA6 filament designed for FDM/FFF 3D printers that accept 1.75 mm filament. The PA6 base offers improved heat resistance and toughness compared with standard polyesters, while short carbon fibers increase stiffness, dimensional stability and surface rigidity. The filament is supplied on a reusable spool in black, intended for continuous use in functional prototypes, mechanical parts, jigs and fixtures that require higher rigidity and resistance to elevated temperatures.

Advantages

This PA6-CF filament combines the thermal and mechanical benefits of polyamide with the reinforcing properties of carbon fibers to deliver parts with greater stiffness and reduced warpage. The carbon-fiber content improves load-bearing capacity and dimensional accuracy in structural prints, while the PA6 matrix provides elevated heat resistance and abrasion performance. The reusable spool supports multiple print jobs and helps reduce waste compared with single-use packaging.

Suitable for

• Functional prototypes and end-use mechanical components
• Gears, housings and structural brackets
• Jigs, fixtures and tooling aids used in assembly or manufacturing
• Applications requiring improved stiffness, dimensional stability and heat resistance

Key specifications

• Material: PA6 (polyamide) reinforced with short carbon fibers
• Nominal diameter: 1.75 mm
• Net filament weight: 1 kg
• Color: Black
• Packaging: Reusable spool suitable for repeated use
• Recommended printing technology: FDM/FFF

How to use

Load the 1.75 mm filament into a compatible FDM/FFF printer following the printer manufacturer’s filament-loading procedure. Use a hardened steel or wear-resistant nozzle to reduce abrasion from carbon fibers and set extrusion temperature according to the printer or filament manufacturer's guidance for PA6-based materials. Ensure a heated build platform and, where possible, an enclosed or heated chamber to minimise warpage and improve layer adhesion. Calibrate retraction, print speed and first-layer settings to achieve consistent extrusion and dimensional accuracy.

Usage recommendations

For best results, use a hardened nozzle, enable an enclosed build environment or heated chamber, and print on a suitably prepared bed surface with appropriate adhesion methods. Allow printed parts to cool gradually to reduce internal stresses. Store the filament on the reusable spool in a dry environment or sealed container with desiccant when not in use to preserve material properties.
