Feature: 1. 【40-500mm/s Printing Speed】With enhanced fluidity, Kingroon RAPID PETG filament melts rapidly and flows smoothly, allowing for up to 500mm/s fast printing speed. You can complete the projects quickly without compromising on quality, bring your ideas to life with high-speed printing. 2. 【Dimensional Accuracy & Consistency】These 3D Printer PETG filaments have very strict tolerances. Diameter is 1.75mm with a dimensional accuracy of + / - 0.02mm 1kg spool (2.2lbs). 3. 【Enhanced Strength & Toughness】Kingroon RAPID PETG filament features high flexural modulus and elongation at break, which makes it resistant to brittleness and cracking, bringing excellent results for printing functional parts 4. 【Wide Compatibility】HS-PETG works perfectly with all common 1.75mm FDM 3D printers, thanks to the high quality standards in terms of manufacturing accuracy. 5. 【HS PETG filament Recommend Settings】To achieve the best printing results with PETG filament, we recommend printing at a nozzle temperature of 220°C, a bed temperature of 75-90℃.
