PET CF

PET CF filament is a high-performance 3D printing material that combines the durability of PET with the added strength and stiffness of carbon fiber. It offers excellent layer adhesion, improved rigidity, and a lightweight structure, making it ideal for functional parts, mechanical components, and engineering applications. With reduced warping compared to ABS and a clean matte finish, PET CF delivers professional results on both open and enclosed printers.

Why Choose PET CF?

  • High strength and stiffness from carbon fiber reinforcement
  • Lightweight yet highly durable
  • Improved heat resistance over standard PETG
  • Matte, professional surface finish
  • Low warping with strong layer adhesion

Explore the PET CF Collection

Our PET CF collection is designed for users who need stronger, more rigid prints. PET Carbon Fiber delivers enhanced stiffness and dimensional stability, making it perfect for brackets, mounts, and structural parts where standard filaments may flex or fail.

Find the Right PET CF Filament

Choose PET CF filament when you need engineering-grade performance with minimal flex. It’s ideal for load-bearing parts, functional prototypes, and high-strength applications. For best results, a hardened steel nozzle is recommended due to the abrasive carbon fiber content. All spools are 1.75 mm and compatible with Bambu Lab, Prusa, Creality, and Ender series printers.
