How small could a 3D Printer be?

Printers which can produce three-dimensional objects have been available for years. However, at the Vienna University of Technology, a printing device has now been developed, which is much smaller, lighter and cheaper than ordinary 3D-printers. They claim that with this kind of printer, everyone could produce small, taylor-made 3D-objects at home, using building plans from the internet – and this could save money for expensive custom-built spare parts.
