Why choose Siraya Tech Fibreheart PPA-CF Core

Revolutionary Carbon Fiber Core Technology

- With 25% core-shell carbon fiber

With a 25% core-concentrated carbon fiber design, PAHT-CF Core Black achieves exceptional stiffness, lightweight durability, and impressive Z-axis strength, making it ideal for high-performance parts that demand superior structural integrity.

High-Performance PPA Nylon material pic 3

High-Performance PPA Nylon Base

Built with advanced Polyphthalamide (PPA) Nylon, PAHT-CF Core filament delivers outstanding strength, chemical resistance, and thermal stability. It maintains low moisture absorption, ensuring reduced warpage and consistent results in any environment.

Engineered for Extreme Heat and Stress

Perfect for automotive and industrial applications, this filament retains its strength and shape under high temperatures, offering excellent abrasion resistance and dimensional stability in challenging conditions.

PAHT-CF PPA-CF Core Filament - Versatile Application Potential

Versatile Application Potential

From automotive and aerospace to industrial tooling and consumer goods, PAHT-CF Core Black is ideal for creating lightweight, heat-resistant, and durable components, making it the top choice for engineers and makers in demanding applications.

Customized aluminum bag packaging, more water-resistant

Use customized higher-grade and thicker aluminum tape for vacuum packaging.

Aluminum bags have lower water vapor permeability and can better maintain filament performance.

Saving your time: It can be printed directly without drying after arrival!

PAHT-CF Core is dried and sealed into aluminum bags, and can be printed directly without having to be dried again after the first delivery.

(Unless the filament appears to have absorbed water obviously!)

FAQ

Please be aware that using CHT-style multipath nozzles with Fibreheart PPA-CF Core may result in a significantly rougher print surface.

The unique design of these nozzles disrupts and redistributes the carbon fiber core within the filament, leading to dispersed fibers and a compromised surface finish.

For optimal print quality, we recommend using standard hardened steel nozzles with a 0.4mm or larger opening.

A high-temperature 3D printer is recommended (Nozzle: 280-300°C, Bed: 100-120°C).

An all-metal hot end is required to withstand high printing temperatures.

An enclosed printer is recommended to maintain stable temperatures and reduce warping.

A hardened steel or higher grade nozzle (minimum 0.4mm) is recommended to reduce wear and maintain print quality.

Do not use brass nozzles, as the carbon fiber content will wear them down quickly.

📌 Store in a dry box with relative humidity below 15%

📌 Promptly reseal packaging after use.

Do not dry the filament right after opening the packaging, as Siraya Tech dries all filaments before package. Overdrying a dried filament can trigger the annealing process and make the filament unprintable.

Dry filament at 100-120°C for 4-6 hours to restore print quality only if the filament is showing signs of moisture absorption (poor printing surface).

No, it is not compatible. The high carbon fiber content makes PPA-CF Core brittle, and it may break in AMS’s long and tightly curved feed tubes, leading to feeding issues or print failures. We recommend using direct drive or a short-path extrusion system for the best printing performance.
