It is recommended that you use Cura to prepare your digital model for the 3D printers. Cura is a free “slicing” software, available for download HERE. It works on Mac, PC, and Linux. The purpose of a slicing software is to divide your model up into instructions for your specific printer to follow. These instructions are customizable, allowing you to change the settings for specific objects, even though you are printing on the same printer.
