The black PETG filament (1.75mm) is ideal for 3D printing strong objects. PETG is a hydrophobic substance (water-repellent) and has a low shrinkage content, which significantly improves printing. PETG is recyclable, can print objects in any shape, has very strong mechanical properties and a nice shiny look. Use of a heated bed is optional.
