Fiberon™ PET-GF15

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.

Printing Tips

The only requirements you need to print this material is an all-metal hotend that can reach 280˚C - 310˚C, and a hardened nozzle due to the abrasiveness.

• Print a bit slower if experiencing any layer adhesion issues.

• Keep cooling fan off.

• Anneal the print at 120˚ for 10h for the best layer adhesion and temperature resistance.

FAQ

What is PET-GF15?

PET-GF15 is a glass-fiber-reinforced PET filament that combines industrial-grade strength with everyday printability.

Do I have to anneal my PET-CF17?

No. Annealing is only needed if your printed part must resist temperatures above 80°C.

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.

How should I store PET-GF15?

PET-GF15 is moisture-sensitive. Keep it sealed and dry, ideally below 20% relative humidity.

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.

Printing Requirements

• All-metal hotend 270˚C+

• Hardened nozzle

• Annealing post printing

• You may need a filament dryer depending on the humidity of your environment. Keep dry when not in use.
