FILAMENT SENSOR COVER MK3S+

The Prusa PETG filament spool is a high-quality 3D printing material optimized for creating the Filament Sensor Cover MK3s+. PETG (Polyethylene Terephthalate Glycol) combines the best properties of ABS and Acrylic: it is tough, heat-resistant, and chemically resistant, while also being easy to process. Unlike ABS, PETG warps very little and does not require a heated enclosure. The material is characterized by high toughness and impact strength, making it ideal for functional parts like housings and protective covers. PETG is also odor-neutral and does not emit harmful fumes at high temperatures. Recommended printing temperatures range between 220°C and 250°C, while the print bed should be heated to 70-85°C. Good adhesion is achieved on PEI or glass bead sheets. PETG is perfect for mechanically stressed parts, enclosures, and outdoor applications. Its strengths include high impact resistance and good chemical resistance. Note that PETG is sensitive to moisture and should be dried before printing to avoid print defects. It is also slightly more prone to stringing than PLA.
