Make a 3-D Printer With Lego Bricks
A 3-D printer is expensive -- thousands of dollars -- and they take up a lot of space in your study or garage. But now you can make one that disassembles, uses no odd chemicals in the printing, and is easy to use.
It's called the MakerLegoBot. It was designed by Will Gorman, a software engineer in Florida. He showed off his creation at the LegoWorld show last year. The Battlebricks site has detailed instructions describing how to build it. Gorman used a few Lego Mindstorm sets, and using a piece of software called MLCAD (downloadable from the site) one can send commands to build just about anything that can be made with Lego bricks, though the size of the object is limited to a few cubic feet.
