High-quality 3D printing at home has just come one step closer. Researchers at the Vienna University of Technology in Austria have presented the smallest 3D printer to date. At the size of a carton of milk and weighs 1.5 kilograms, it currently costs around €1,200 but the makers expect the price to drop quickly.

The printer uses stereolithography: it hardens layers of synthetic resin by an intense beam of light of only .05mm wide. So not only is this printer small and cheap, but it also prints at a very high resolution!
