Printing time depends on the settings the .Gcode file is associated with. Small sized, medium quality settings, for example a checkers chip printed at 200 microns/layer can take up to 10 – 20 minutes. Larger objects with the same quality settings can even take several hours to print; if you print the same large object […]
