How can you even call your house (or apartment or shed) a home without a 3D printer for all your small little plastic doodad needs? The $5,995 Ultimaker S5 is the best you can get, a behemoth that makes large-volume prints with good quality. It's easy to set up and control via the built-in touch screen. Having dual extruders means it can print with two colours at once. It'll even use a water-soluble plastic that can act as a support for heavy parts as the printing happens.
