The grey Zortrax Z-PETG filament is a strong plastic with a small shrinkage factor. Z-PETG is resistant to UV light, oil, lubricants and has a high hardness. This makes the material ideal for prints that need to be very strong, often used in machines or parts of radio controlled vehicles. Thanks to its high hardness, products made of Z-PETG can be used outdoors for a long time without loss of material performance. The filament has a diameter of 1.75mm and a weight of 0.8kg.
