Strength and mechanical performance: Fibreheart PETG-CF Pro HF is based on a glycol-modified PETG matrix reinforced with short carbon fibers. This combination significantly increases stiffness and dimensional accuracy compared to standard PETG, while maintaining high impact resistance. The material is ideal for functional prototypes, mechanical components, fixtures, and tools where precision and strength are crucial.

High-flow formulation for faster printing: The Pro HF formulation is designed for higher extrusion rates, allowing for increased printing speeds without compromising surface quality or layer adhesion. This makes the material particularly well-suited for larger prints and production-oriented applications where time savings are important.

Reliable results and consistent print quality: Despite its advanced material properties, PETG-CF Pro HF remains easy to process. It offers excellent layer adhesion and minimal warping, even with more complex geometries. Its resistance to moisture, UV radiation, and many chemicals ensures long-lasting performance both indoors and outdoors.

Printing recommendations: Due to the abrasive properties of carbon fibers, a hardened steel or wear-resistant nozzle is recommended. A nozzle opening of 0.4 mm or larger provides the best balance between detail accuracy and flow. A closed printing chamber is not strictly necessary, but it can improve temperature stability and yield better results with larger parts.
