1、【Mechanical Properties】Tensile strength (X-Y): 45.99(MPa)±10%, Elongation at break (X-Y): 10.71(%)±10%, Bending strength: 59(MPa)±10%, Bending modulus: 1080(MPa)±10%, Charpy impact strength: 326 (J/m)±10%，Heat Deflection Temperature: 64℃（0.45MPa), Melt flow rate: 9.72g/10min. 2、【 Clog-free & Bubble-Free】No warping, no jamming and no blobs issues to guarantee a smooth and stable printing experience. Please make sure to hold the tip of the filament as it may create nodes. Holes on the side of the spool can be used to prevent this issue. 3、【Wide Compatibility】PETG 1.75mm 3D printer filament has great bed adhesion, very consistent color and dimensional accuracy with a higher toughness than regular PLA, fit most FDM 3D printers on the market, such as neptune 2, neptune 3, Ender 3 and more. 4、【Reusable Vacuum-Sealed Packaging】PETG 3D printer filament 1.75 complete drying for 24 hours before packaging and vacuumed sealed with desiccant to keep it dry. Prevent dust and please store into re-sealable bag with zip locked timely after using to maintain excellent. 5、【Recommended Setting】We recommended petg filament extrusion/nozzle temperature 220-250℃, hot bed temperature 75-90°C, support printing speed: 50-100mm/s. PETG 3D printer filament to be strict tolerances, diameter 1.75mm, dimensional accuracy ±0.02 mm. We have 11 colors to choose - White, Orange Red, Orange, Black, Red, Yellow, Grey, Blue, Transparent, Beige, Silver.
