Sure, manufacturing companies have 3-D printers that are able to weld metal pieces. You can even send designs to Shapeways to get them printed in steel. But wouldn’t you want your own metal 3-D printer at home? One California man is making it happen. DIY hobbyist Steve Delaire is working on making a home 3-D printer that lays down wire, layer by layer, and welds it together.

Delaire has shown his machine at a San Francisco Bay Area Maker Faire, where Slashdot talked with him and filmed his machine. Delaire posts his problems and progress on his blog. A few days ago, he wrote about why he wants a 3-D metal printer:
