Overview

Not a hobby PLA, Fibreheart is a polyphthalamide nylon reinforced with chopped carbon fiber for strong, stiff parts that hold their shape under heat. Low moisture uptake makes prints consistent in humid rooms, and the material is self-lubricating for moving parts.

Parts that live near engines or machinery are the target: carbon fiber adds stiffness while the PPA base resists heat and chemicals better than standard nylon. Lower moisture uptake means fewer drying headaches. The listing gives no filament diameter, nozzle temperature or hardware needs.

Who it's for

Workshops and product developers making functional parts for hot or demanding settings get an industrial-grade material. Casual printers will find it harder to tune and unnecessary for decorative work.

Pros and cons

Pros
  • Carbon fiber adds stiffness
  • High heat resistance
  • Low moisture uptake for nylon
  • Self-lubricating for moving parts
Cons
  • Filament diameter not listed
  • Print temperatures not listed
  • Hardware needs not stated

Performance notes

Stiffness comes from the chopped carbon fiber, which reinforces the PPA matrix and limits flex under load. The PPA base holds dimensional stability at high temperatures, which governs use near engines and motors. Low moisture absorption reduces the stringing and weak layers wet nylon causes.

Frequently asked questions

How hot can Fibreheart PPA-CF parts get?

Siraya Tech says the material maintains its strength and dimensional stability up to 195C.

Is Fibreheart PPA-CF the same as standard nylon?

No. It is a polyphthalamide, which Siraya Tech says surpasses traditional nylon in strength, chemical resistance and thermal stability, with lower moisture absorption.

How much carbon fiber is in Fibreheart PPA-CF?

15% chopped carbon fiber.
