You have come this far because you have a 3D printer, GREAT. You've connected it to the network, levelled it and loaded the filament. But wait a minute, how do I send my 3D file so my printer can understand it? This is where slicers come into play.
When we talk about slicer, we refer to the software that slices our 3d file into layers, thus transforming an STL file into a GCODE file. In addition to slicing the object, the slicer adds other parameters such as temperature and speed among many others.
