Siraya Tech Fibreheart PPA-CF Core Filament features a revolutionary core-shell structure for unmatched performance. It delivers 25% carbon fiber concentrated in the core for optimized fiber distribution and enhanced mechanical properties. The pure PPA shell ensures superior layer adhesion for superior Z-axis strength, while the protective outer layer minimizes abrasive fiber contact with printer components. This filament offers high strength and stiffness, superior dimensional stability, reduced warping, and extended equipment life, making it ideal for precise and durable 3D prints.
