Bambu PETG-CF is a composite material consisting of PETG and carbon fiber. The new formula greatly improved printing quality by reducing nozzle clogging and clumping compared to traditional PETG. With the addition of carbon fiber, Bambu PETG-CF offers improved strength while maintaining good toughness and a shiny look. It is an ideal material for drone parts, racing models, and various functional parts that require both high performance, especially impact strength, and a sleek appearance.
Bambu PETG-CF is improved with a modified formula that specifically addresses the issue of clumping and sticking to nozzle during PETG printing.
Carbon fiber brings advanced texture to the print surface, while retaining the shine of PETG itself.
Carbon fiber brings soft reflection, minimal layer lines and a unique delicate texture.
Different from PLA-CF's matte finish, PETG-CF offers a shiny finish and thus one more choice.
The addition of carbon fiber also significantly enhances the XY strength of PETG without sacrificing layer bonding.

• Bambu PETG-CF needs proper drying before printing. Drying conditions: 65℃ for 8 hrs. Store in a dry environment after use. Dry before use if the material absorbs moisture. For more details please refer to: Filament drying instructions on WIKI.
• To get stronger Z-adhesion, please set a higher infill density, and do not use an open-frame printer or set too large fan percentages to avoid over cooling.
• To get shinier looks, set lower speeds and relatively higher temperatures.
