Fiberon™ PET-GF15 – Glass-Fiber-Reinforced PET Filament
Bridge the gap between everyday usability and industrial performance.
High-Strength, Heat-Resistant Engineering Filament
Fiberon™ PET-GF15 combines PET with 15% glass fiber reinforcement to deliver exceptional stiffness, dimensional stability, and thermal resistance. It’s engineered for users who need the toughness of an engineering-grade filament without sacrificing printability.
Industrial-Level Performance, Everyday Usability
With a bending strength of 104 MPa and HDT up to 133 °C (0.45MPa, after annealing), PET-GF15 withstands high stress and high-temperature environments where other materials would deform. It prints easily on most modern FDM printers, even at speeds up to 250 mm/s.
Excellent Surface Finish & AMS Compatible
Achieve smooth, professional-grade prints with a refined texture that minimizes visible layer lines. Available in six vibrant colors, Fiberon™ PET-GF15 works seamlessly with most multi-material systems, perfect for multi-color and multi-material projects.
Dimensional Stability & Low Warping
PET-GF15 maintains consistent accuracy and minimal warping, even on large projects. After annealing, dimensional change stays below 0.5 %, ensuring tight tolerances for functional parts that demand reliability and precision.
Designed for Professionals & Makers Alike
Ideal for automotive parts, jigs, fixtures, Industrial parts, and prototyping, PET-GF15 offers excellent toughness and resists brittleness. Whether you’re a professional engineer or advanced hobbyist, PET-GF15 delivers industrial-grade results with a user-friendly experience.
Warning: PET-GF filament adheres strongly to textured PEI plates—allow plate to cool before removal or use a release agent to prevent damage.

What is PET-GF15?
PET-GF15 is a glass-fiber-reinforced PET filament that combines industrial-grade strength with everyday printability.
Is Fiberon™ PET-GF15 easy to print with?
Yes. Despite its industrial-level strength, PET-GF15 is designed for accessible printing.
Do I need a hardened nozzle to print PET-GF15?
Yes, because it contains glass fibers Fiberon™ PET-GF15 will wear out regular nozzles quickly.
Can I print PET-GF15 on an open-frame printer?
Yes, but for best results, an enclosed or heated-chamber printer is recommended.
Is annealing required?
No. Annealing is only needed if your printed part must resist temperatures above 80°C. You can anneal PET-GF15 at
120°C for 16 hours.
How should I store PET-GF15?
PET-GF15 is moisture-sensitive. Keep it sealed and dry, ideally below 20% relative humidity.
Is Fiberon™ PET-GF15 AMS-compatible?
Yes. PET-GF15 feeds smoothly through Bambu AMS and other multi-material systems.
What applications is PET-GF15 best suited for?
Ideal for functional prototypes, jigs, fixtures, automotive parts, brackets, and enclosures.
How does the surface finish compare to other glass-fiber filaments?
PET-GF15 produces smoother prints with less fiber exposure compared to other CF or GF Filaments.
Is the packaging sustainable?
Yes. Fiberon™ PET-GF15 is shipped in a fully recyclable cardboard spool and box.
