Low-cost, open-source 3D printer looks beyond plastic

.....if you want to make things out of plastic. Unfortunately, the price of commercial metal 3D printers means the ability to print metal objects has remained out of reach of most people. That could be set to change with a team from Michigan Technical University building a 3D metal printer for under $1,500.
The 3D printer was created by Joshua Pearce, an Associate Professor of Materials Science and Engineering, and his team from parts including a small commercial MIG welder and an open-source microcontroller. It forms complex geometric shapes by laying down thin layers of steel, but Pearce admits the printer is still a work in progress, with a sprocket the most intricate piece the printer has produced so far. That's where the open-source nature of the device comes in.
