PETG-CF Bambu PETG-CF significantly improves the stiffness of regular PETG while enhancing both strength and toughness, making it an all-rounder in mechanical properties among basic filaments, perfect for load-bearing and functional parts. The new formula also greatly reduces clumping and stringing compared to regular PETG. It delivers a signature carbon fiber texture with a glossier finish than Bambu PLA-CF. Enhanced Strength and Stiffness With the addition of carbon fiber, Bambu PETG-CF overcomes the low stiffness of regular PETG and delivers improved strength and toughness, making it a solid choice for structural and load-bearing parts.
