Polymaker Fiberon PET-GF Black 1.75mm 1kg
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.
