ESUN PETG+ 1.75mm Black 1kg Paper Roll Filament

Printing with standard PETG often means compromising between strength and ease of use, but the ESUN PETG+ 1.75mm Black 1kg Paper Roll filament changes that. This advanced PETG+ material delivers the durability and chemical resistance of PETG with improved flow and layer adhesion, making it a reliable choice for functional parts, mechanical components, and everyday prototypes. The 1 kg spool is wound on an eco-friendly paper roll, reducing plastic waste without sacrificing performance. With a diameter tolerance of ±0.03 mm, you get consistent extrusion and fewer clogs, while the low warping tendency ensures clean prints on a variety of build surfaces.

Who is it for

This filament is ideal for hobbyists, educators, and professionals who need tough, impact-resistant parts without the hassle of high-temperature materials. It works on most FDM 3D printers with a heated bed, and the black color provides a sleek, professional finish for enclosures, brackets, tools, and cosplay props. Whether you are upgrading from PLA or seeking a more forgiving alternative to ABS, PETG+ offers a balanced blend of strength, flexibility, and printability.

Tips

Store the filament in a dry box or resealable bag with desiccant when not in use to maintain print quality. Use a glue stick or PEI sheet on the heated bed for best adhesion, and allow the part to cool before removal to prevent warping. For detailed prints, reduce speed to 40-60 mm/s and increase cooling fan to 50-80% after the first layers.
