When it comes to FDM-based desktop 3D printers, the majority of them all work with the same basic Cartesian format. An extruder moves along an x,y and z-axis in a grid-like format to slowly fabricate an object one layer at a time. In addition to Cartesian-based systems, delta-robot systems also exist, but are used less commonly. We have not seen many FDM 3D printers stray from these two methods, besides in a few rare machines, most of which have yet to be released.
