Fiberon™ PA6-GF25

Fiberon™ PA6-GF25: High-performance glass fiber reinforced nylon 6 filament

Exceptional strength, rigidity and heat resistance

Fiberon™ PA6-GF25 is a glass fiber reinforced PA6 (nylon 6) filament containing 25% glass fiber by weight. This advanced composite material offers outstanding mechanical strength, high stiffness, and excellent thermal properties, making it ideal for demanding engineering, automotive, aerospace, and industrial applications.

Main features

• Reinforced with 25% fiberglass: Significantly improves stiffness, strength and dimensional stability.
• Excellent thermal properties: Withstands high temperatures, with a heat deflection temperature (HDT) of up to 191 °C after annealing.
• Superior layer adhesion: Maintains a strong bond between layers for durable, cohesive prints. Minimal warping: Warp-Free™ technology allows printing at lower bed temperatures (40–50 °C), reducing the risk of warping and improving dimensional accuracy.
• High-speed printing: Compatible with print speeds up to 300 mm/s.

Easy to use for advanced users

Fiberon™ PA6-GF25 does not require a heated chamber and can be reliably printed on high-performance FDM/FFF 3D printers equipped with a hardened steel nozzle, thanks to the abrasive nature of the glass fibers. For best results, it is recommended to dry the filament before printing and perform an annealing after printing (100°C for 10–16 hours) to maximize mechanical and thermal performance.

Same formula of trust, new name

Fiberon™ PA6-GF25 is the same high-performance material as PolyMide™ PA6-GF, now under the Fiberon™ brand.

Choose Fiberon™ PA6-GF25 for applications that require maximum strength, stiffness, and heat resistance without compromising printability or interlayer adhesion.

Formerly known as PolyMide PA6-GF.
