Filament Gembird PETG Natural [1,75mm, 1kg]

PETG 1.75 mm 1 kg – A durable, tough and versatile filament for 3D printing

Discover the versatile PETG filament (1.75 mm, 1 kg), which offers the ideal balance between the printability of PLA and the mechanical and chemical resistance of ABS. Glycol-modified polyethylene terephthalate (PETG) is a strong and tough thermoplastic with minimal shrinkage, allowing for easy printing of both large and flat models without warping or layer delamination.

The high precision of the filament, with a tolerance of ±0.05 mm, ensures smooth extrusion without jamming in the extruder. PETG excels in terms of excellent inter-layer adhesion, high tensile strength (up to 120% elongation at break) and outstanding chemical resistance. Furthermore, the material is fully recyclable and ideal for functional parts for both indoor and outdoor use.

Key benefits

• High strength and impact resistance: The material is more flexible and less brittle than PLA or acrylic.
• Minimal shrinkage and excellent adhesion: Enables easy printing of large-scale prints without warping or peeling from the build plate.
• High chemical resistance: Excellent resistance to acids, alkalis and cleaning agents.
• 100% recyclable: A more environmentally friendly option with a low carbon footprint.
• Wide compatibility: Adheres easily to glass, PEI sheets, Kapton and other common printing surfaces.

Recommended print settings

Print at a nozzle temperature of 220–260 °C and with the heated bed set to 70–85 °C. To prevent stringing, we recommend slightly reducing the nozzle temperature, fine-tuning retraction settings and setting the print cooling to 30–60 per cent. To make it easier to remove the print from a glass or PEI bed (to prevent damage to the surface caused by excessive adhesion), we recommend using a release layer (e.g. 3Dlac or office glue).
