Using this Sunlu ABS filament is easy. First, make sure your 3D printer or 3D pen is compatible with 1.75mm filament. Set the printing temperature between 230 - 270°C and the platform temperature from 80 - 120 °C. Then feed the filament into your device and start printing at a speed of 50 - 100 mm/s. When handling the filament, be careful not to bend it too much as it might affect the printing quality. Store it in a dry place to keep it in good condition. After use, wind the remaining filament neatly to avoid tangling. If you encounter any issues during printing, check the temperature settings and make sure the filament is feeding smoothly.
