PETGPrusa
Prusament PETG Magnetite 40% Grey is a premium 3D printing filament made from PETG (Polyethylene Terephthalate Glycol), distinguished by its deep, mineral gray tone that resembles natural stone. This material combines the best properties of PLA and ABS: it is strong, chemically resistant, and tough, while maintaining good thermal stability. The Magnetite color imparts a sophisticated, matte finish to printed objects, making it ideal for both aesthetic and functional applications. The filament has a diameter of 1.75 mm and is available in convenient 10-packs of 1 kg each, perfect for high-volume projects. Thanks to integrated NFC technology, users can easily read filament data and print settings using an NFC-enabled device. Recommended print settings include a nozzle temperature of 230–255 °C and a heated bed temperature of 70–85 °C. PETG is less prone to warping than ABS. Suitable applications include functional prototypes, mechanical parts, enclosures, and decorative objects. Strengths include high toughness, UV and chemical resistance, and ease of use. Limitations include sensitivity to moisture (store dry before printing) and the need for careful cooling adjustment to ensure optimal surface quality.
