BambuLab PETG-CF Malachite Green Filament 1.75mm 1kg with Spool

BambuLab PETG-CF Malachite Green is a high-performance carbon fiber reinforced PETG filament designed for demanding 3D printing applications. This 1kg spool features a 1.75mm diameter with tight tolerances, delivering exceptional stiffness, strength, and heat resistance. The matte malachite green finish provides a premium aesthetic while the carbon fiber content (~15-20%) enhances dimensional stability and reduces warping.

Advantages

Compared to standard PETG, PETG-CF offers significantly higher tensile and flexural strength, making it ideal for functional parts. The carbon fiber reinforcement minimizes shrinkage (0.4-0.6%) and improves layer adhesion. It prints smoothly at speeds up to 150 mm/s with a hardened steel nozzle (0.4mm or larger). The spool is made from ABS plastic, ensuring durability during storage and use.

Suitable for

• Functional prototypes and end-use parts
• Tools, fixtures, and jigs
• Structural components requiring high stiffness
• Automotive and industrial applications
• Enclosures and brackets

Recommendations

For best results, use a hardened steel nozzle and ensure the filament is stored in a dry environment. A glue stick on the build plate is recommended for adhesion. This filament is not suitable for brass nozzles due to abrasiveness.
