Using this Colorfabb Semi - Matte PETG filament for 3D printing is quite straightforward. First, set your 3D printer's temperature between 235C and 255C and the print speed from 30 to 50 mm/s. Heat the bed to 70 - 80C. If you want your print to look its best, especially for parts with overhangs or small details, use a 75/100% fan cooling. But if you're more concerned about the mechanical strength of your print, use the least amount of cooling needed. When storing the filament, keep it in a dry place to prevent moisture absorption which can affect the print quality. Also, always refer to the TDS and SDS documents for any safety or technical details. And if you run into any issues, the Colorfabb team of professionals is there to help you out.
