PETG filament combines glycol with standard PET material to eliminate brittleness. The result is improved durability and tensile strength. PETG is an industrial-grade 3D printing material designed to work in extreme environments. It’s resistant to oils and greases. The filament doesn’t degrade over time and immune to UV light. Use it to test your prototypes in various industrial conditions. Low shrinkage allows to 3D print complex mechanical elements as well as final components. The material’s strength can be used to create working parts designed to endure stress like springs, shock absorbers, and manufacturing tools.
