Scientists build a low-cost, open-source 3-D metal printer

[Baron Greenback]

Until now, 3D printing has been a polymer affair, with most people in the maker community using the machines to make all manner of plastic consumer goods, from tent stakes to chess sets. A new low-cost 3D printer developed by Michigan Technological University's Joshua Pearce and his team could add hammers to that list. The detailed plans, software and firmware are all freely available and open-source, meaning anyone can use them to make their own metal 3D printer.

love the "However, because of safety concerns, Pearce suggests that for now it would be better off in the hands of a shop, garage or skilled DIYer, since it requires more safety gear and fire protection equipment than the typical plastic 3D printer." no st Sherlock!

If you search the articles, no one shows a picture of the output.

Additionally, what they don't mention is that the output probably requires machining to be of any use.
