Bambu Lab PETG-CF Black 1.75mm Filament Refill

For best results, an extruder temperature of 240-270°C and a heatbed temperature of 65-75°C are recommended. These settings ensure good layer adhesion and minimize warping, crucial for the carbon fiber reinforced material. Adjust within these ranges based on your specific printer and part geometry for optimal performance and surface finish.

While PETG-CF offers enhanced mechanical properties, it generally prints with minimal stringing and clumping, similar to well-tuned standard PETG. However, its abrasive nature due to carbon fibers requires a hardened steel nozzle to prevent wear. Proper drying and bed adhesion are also key for consistent results and avoiding extrusion issues.

This filament excels in applications requiring high stiffness, strength, and durability, especially in demanding environments. Ideal uses include functional prototypes, load-bearing parts, jigs and fixtures, and outdoor components exposed to heat and moisture. Its professional finish also suits aesthetic functional parts where both strength and appearance are critical.

To maintain optimal print quality and prevent moisture absorption, PETG-CF should be stored in a dry, sealed environment, preferably with desiccant. If the filament has absorbed moisture, it is recommended to dry it thoroughly (e.g., at 60-70°C for 4-6 hours in a filament dryer) before printing to avoid defects like bubbling, stringing, and poor layer adhesion.
