3D printing slicer software controls every aspect of your 3D print. It translates 3D models into instructions your printer understands. Slicer software can also provide other features, including selecting the different materials you wish to print with, optimizing your printer’s settings for each material and other advanced capabilities including incorporating multiple parts into one print, setting how solid (infill) your part should be and creating support structures in the event they are needed to print your part.
