Anyone with access to a welder and the Internet soon could make his or her own replacement parts or tools with a new 3D metal printer that can be built in any garage.
Now, scientists have built an open-source 3D metal printer that costs under $1,200, sharing their design and software with the maker community.
"We have open-sourced the plans," in the hopes of accelerating the technology by allowing others to build upon the design, said project leader Joshua Pearce, a materials engineer at Michigan Technological University in Houghton.
Link. Being open sourced, I expect this design to be developed rapidly. There's been a bit of stink raised recently by gun control advocates seeking to ban 3D printing of plastic guns because they are undetectable. 3D printing metal guns would make that moot.
This is a liberty enabling technology and control freaks like Schumer and Feinstein can't stop the signal.
