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

BambuLab PET-CF 1.75 mm 1 kg with reusable spool — Black is a carbon-fiber-reinforced PET-based 3D printing filament designed for parts that require increased stiffness and improved dimensional stability. The filament has a 1.75 mm diameter and is supplied in a 1 kg package on a reusable spool in black color, offering compatibility with printers that accept PET-based composite materials and standard 1.75 mm filaments.

Advantages

The carbon fiber reinforcement increases tensile stiffness and reduces part deformation compared with standard PET materials, while the PET base provides good layer adhesion and lower moisture sensitivity than some other polymers. Supplied on a reusable spool, the filament reduces packaging waste and simplifies storage and handling. The black color provides consistent surface appearance for functional parts and prototypes.

Suitable for

• Functional prototypes requiring higher stiffness and dimensional accuracy
• Mechanical parts and fixtures, such as brackets, housings and mounts
• Components exposed to moderate mechanical loads and where reduced creep is beneficial
• Applications that benefit from a reusable spool for workshop or production environments

Key specifications

• Material: PET-based composite reinforced with short carbon fibers
• Diameter: 1.75 mm
• Net weight: 1 kg filament on spool
• Color: Black
• Packaging: Reusable spool suitable for standard spool holders
• Intended use: Fused filament fabrication (FFF) / FDM 3D printing

How to use

Load the 1.75 mm filament into a compatible FFF/FDM 3D printer following the printer manufacturer's filament loading procedure. Use a hardened or wear-resistant nozzle to minimize abrasion from the carbon fibers. Set printing temperatures and fan settings according to the printer and part requirements; start with manufacturer-recommended temperature ranges for PET-based composites and adjust to achieve consistent extrusion and layer adhesion. Store unused filament on the reusable spool in a dry environment to maintain print quality.

Usage recommendations

For best results, use a hardened steel or ruby nozzle, set moderate print speeds to balance surface finish and mechanical performance, and consider annealing if the application demands further dimensional stability. Keep filament dry and avoid prolonged exposure to humid environments.
