Polymaker Fiberon PET-GF15 1.75 mm
Glass fiber reinforced PET filament for technical FDM/FFF prints
Product description
Polymaker Fiberon PET-GF15 is a glass fiber reinforced PET filament for technical and functional 3D printed parts. The material is designed for high stiffness, good dimensional stability, and reliable processing in FDM/FFF printing.
Due to the glass fiber reinforcement, PET-GF15 is particularly suitable for components such as brackets, fixtures, housings, prototypes, and technical applications where dimensional stability and resilience are important.
For reliable results, the filament should be stored dry and, if moisture is absorbed, dried before printing in a suitable filament dryer or drying device. Due to the glass fiber filling, a hardened nozzle is recommended.
Polymaker notes that PET-GF filament can adhere strongly to textured PEI print beds. The print bed should cool down before removing the part; if necessary, a suitable release agent can be used.

Frequently Asked Questions about this Filament
How should filament be stored?
Filament should be stored dry and protected from moisture. If the material has absorbed moisture, drying it before printing can improve print quality.
Are print settings the same for every printer?
No. Temperature, speed, cooling and flow settings may need to be adjusted depending on the printer, nozzle, build plate and material condition.
Which filament is best for beginners?
PLA is usually the easiest material for beginners. PETG is a good next step when more toughness and temperature resistance are needed.
Why is dry filament important?
Moist filament can cause stringing, bubbles, rough surfaces and weak layer adhesion. Dry storage helps keep print quality consistent.
Can every filament be printed on every printer?
Not always. Some materials need higher temperatures, an enclosed build chamber or a specific extruder setup. Always check whether your printer is suitable for the material.
How do I improve print quality?
Good print quality depends on dry filament, suitable temperature settings, correct bed adhesion, calibrated flow and a clean nozzle.
