Fibreheart PPA-CF is the most extreme filament we carry. Polyphthalamide with carbon fiber delivers unmatched heat and chemical resistance — capable of replacing metal parts in non-critical applications.
Best for: Metal replacement, chemical exposure, sustained 200°C+ environments
Heat resistance: >250°C
Impact strength: Moderate — stiff and strong but less ductile
Chemical resistance: Outstanding — insoluble in nearly all solvents below 200°C
Print difficulty: Expert only — 300-320°C, zero cooling, brim mandatory, 120°C drying
