Why would i want one at home? I do not even have a 2d printer! I can handle nearly all of my stuff without paper so it is a lot cheaper to go to the copyshop next door. I know a 3d printer is used in a different way but I would rather go to a 3d print shop with high quality printers and a good choice of materials and post print services (polishing, coloring, ...).
