Prototype miniature 3D printer could become an affordable product

With the recent release of the Trimensional app, people can now use their iPhones as inexpensive 3D scanners. Not only can users take three-dimensional images of objects, but they can use those images to create actual physical models ... as long as they have access to a 3D printer. Currently, such printers tend to be large, expensive devices that are usually only found in places like universities or industrial design companies. That could soon change, however, as researchers at the Vienna University of Technology (TU Vienna) have created a prototype compact, affordable 3D printer.
