Filament, PETG Black, 1.75 mm, 1 kg VERSATILE & EASY TO USE Polyethylene terephthalate (PETG) is an amorphous thermoplastic of the polyester family Perfect combination of clarity and strength. The clarity of PETG approaches that of Acrylic and impact resistance is close to Polycarbonate Easy to print with a variety of 3D printers Features Very high strength filament Impact Resistant - PETG is less brittle than acrylic, and is a lower cost alternative to polycarbonate. Chemical Resistant - offers superior chemical resistance when compared with many other transparent plastics. Environmental friendly as it is considered 100% recyclable Very low shrinkage makes printing large flat surfaces a breeze Easily printed on any acrylic, glass, Kapton and other printing platform Specifications Material: PETG, 1.75 mm diameter Weight: 1 kg/spool (2.2 lbs) Density at 240°C: 1.27 g/cm3 Melt Flow Index at g/10min, 200°C/ 5kg: 20 Melt Point: 220 - 260 °C Heat-Deflection-Temperature at 0.455 MPa: 60 - 80 °C Yield Strength at 5mm/min: 50 MPa Impact Strength: 8.7 KJ/m2 Ensile Break: 120 % Diameter: 1.75 ± 0.05 mm Spool dimensions: 200 mm diameter x 67 mm height x 53 mm central hole System requirements A 3D printer with 1.75 mm extruder of temperature around 240 °C, suitable for PETG filament
