Well I think overhang is still an issue for single extruder FDM printers (like the Dremel one). The slicer can generate supports but in my experience this will cause some of these issues: * Print times will double or triple. * Sometimes its really hard to remove the support material. * You will need a lot more material. * Support structures can break while printing because they are thin. * The slicer doesn't create the right support. So most of the time I end up designing support structures myself.
