Designed for strength and precision. The innovative, core-concentrated carbon fiber design strategically places 25% carbon fiber reinforcement in the core of the filament. The result is parts with exceptional stiffness and strength, particularly along the Z-axis, while maintaining a smooth surface. The advanced PPA nylon base offers high thermal resistance and chemical stability, ensuring consistent performance even in challenging environments. Optimized for reliable printing. Fibreheart PPA-CF Core provides excellent layer adhesion and reduced warping due to its low moisture absorption and dimensional stability. The minimized surface fiber stress not only improves print quality but also reduces nozzle wear, thereby extending the lifespan of your printing equipment.
