Fiberon PET-GF15 Black Filament 1.75mm 1Kg

The Polymaker Fiberon PET-GF15 is a glass fiber reinforced PET filament with 15 percent glass fiber content, combining industrial performance with relatively easy processing. With a high flexural strength of 104 MPa and a heat deflection temperature of up to 133 °C after annealing, the material is ideal for functional and mechanically stressed components. Unlike carbon fiber reinforced filaments, PET-GF15 is electrically non-conductive and therefore optimal for electronic applications as well as RF-sensitive components. The uniform glass fiber distribution significantly improves layer adhesion and increases Z-axis strength by up to 73 percent compared to PET-CF17. A smooth, matte surface reduces visible layer lines and gives the components a premium appearance. The filament supports print speeds up to 250 mm/s, is AMS compatible, and comes on a generous 1 kg spool.
