PETG-CF TDS

This PETG-CF 3D printer Filament uses a carbon-fiber- reinforced formulation that retains excellent printability from PETG while delivering higher stiffness, improved dimensional stability and a smooth matte finish. It is well suited for functional parts such as mechanical components, brackets, jigs, enclosures, drone parts, and other print applications where both mechanical performance and surface aesthetics are required.

Key characteristics

Carbon Fiber Reinforced Compared with ordinary PETG, it has higher rigidity, lighter weight, and enhanced strength Low-gloss Surface The carbon fiber provides a fine, uniform matte texture that helps minimize layer lines and gives functional parts a more professional appearance. Application Scenarios Ideal for mechanical components, brackets or supports, jigs, enclosures, drone parts, and any other prints that demand a balance between mechanical strength and visual quality. Recommended Nozzle Carbon fiber is abrasive, so for long-term printing, a hardened steel, ruby or other wear-resistant nozzle is highly recommended. Moisture-proof Requirement PETG-CF is moisture-sensitive and should be stored in a sealed bag or container after opening. If you notice bubbles, rough surface finish, or increased stringing during printing, we recommend thoroughly drying before use. Application Orientation PETG-CF is designed for users who need higher stiffness, better dimensional stability, and a more professional surface finish than standard PETG can provide.

Specimen printing conditions

All test specimens were printed on a Bambu Lab P1S printer. The addition of carbon fiber reinforcement in PETG-CF provides improved stiffness, dimensional stability, and heat resistance compared to standard PETG. Annealing may further relieve internal stresses accumulated during printing and can offer some improvement in heat resistance and dimensional stability. However, since PETG is an amorphous material, the performance gains from annealing are limited. Additionally, parts with complex geometries, thin-walled structures, or tight-tolerance features may experience deformation due to thermal shrinkage. Therefore, annealing is not advised for all the printed parts, and should be evaluated based on the specific requirements of each application.
