Our 3D printer (a heavily hot-rodded Ultimaker 2) is running almost non stop, from cheap plastic caps to plug radiators for shipping, to carbon fibre filled nylon parts that are end use parts on race cars
I make welding jigs and fixtures with it too
They are a big step up from mine. I wonder what the difference in print quality is between a cheapy like mine and a more pro set up ?
Print quality is much of a muchness. I find the ability to run the machine fast , I typically print at 90-100mm p/min speeds is the advantage over the cheaper models
Also I have an enclosure around mine which minimises warping due to temperature variations
