Affordable 3D Metal Printer Developed Based on RepRap
hypnosec writes "Researchers have developed and open-sourced a low-cost 3D metal printer capable of printing metal tools and objects that can be build for under £1,000. A team of researchers led by Associate Professor Joshua Pearce at the Michigan Technological University developed the firmware and the plans for the printer and have made it available freely. The open source 3D printer is definitely a huge leap forward as the starting price of commercial counterparts is around £300,000. Pearce claimed that their technology will not only allow smaller companies and start-ups to build inexpensive prototypes, but it will allow other scientists and researchers to build tools and objects required for their research without having to shell out thousands, and could be used to print parts for machines such as windmills."
It's a modified RepRap; looks like we're getting closer to the RepRap being able to print all of its parts.
You wouldn't download a car........?
More like the wingnuts who attempt to print their own guns will end up disarming, or at least dishanding themselves.
I first tried laser sintering 5 years ago - I got a few steel gun parts custom-made by a "printing" company, then mounted the parts in a real gun and got the proofhouse to shoot it until it died. I was working for a certain very well known luxury gunmaker at the time, and we were investigating new ways of producing parts in very small volume.
The laser sintered parts were as good as, or better than the original parts! And the prices are great too: we paid per cm3 of material "printed", which worked at at just under $900 for a receiver, as opposed to $7500 for the equivalent part machined with conventional tools.
I've known since then that this is the future of metalworking. As a result, I've been holding off upgrading the lathe and the milling machine in my workshop, because I've been waiting for a metal-building machine that doesn't cost a quarter million bucks.
This $1000 thing probably won't be it, but the next generation machines, or the generations after them, will. At last!

I've yet not tried it but not heard any major disasters.
Based on your very thorough review of this product, I'm seriously considering ordering one.

Either the US government rapidly steps in to quash or severely-restrict this technology in the US or their plans to disarm the US population will die stillborn.
If you knew anything about guns, you'd know it only takes a few basic tools and materials to make a functional gun that goes bang without killing its user. You don't need a 3D printer. There's no way to disarm anybody in any circumstances.
I love the smell of dying government tyranny in the morning.
Wishful thinking... It's not the lack of guns that keeps your tyrannical government in place, it's the lack of courage in a population that has turned bovine, uneducated, and more interested in shopping and watching reality shows on TV than in fighting for liberty and moral principles.

The demonization has been going on for a while. Here's an article from almost a year ago: http://www.forbes.com/sites/andygreenberg/2013/01/18/meet-steve-israel-the-congressman-who-wants-to-ban-3d-printable-guns-qa/
Steve Israel wants to ban your access to 3d printers, and he's using guns as a way to get the camel's nose under the tent. Here are some particularly telling quotes from the interview in the story linked above:
What we’re trying to do is make it clear that if you choose to construct a weapon or weapon component using a 3D printer, and it’s homemade, you’ll be subject to penalties.
Catch that? If you're a business, doing it for commercial gain, then he thinks it's okay. If you're the little guy, doing it as a hobby, then simply doing it even if no one ever gets hurt will get you sent to jail.
Steve Israel: But if you’re going to download a blueprint for a plastic weapon that can be brought onto an airplane, there’s a penalty to be paid.
Interviewer: Just for downloading it?
Steve Israel: No, no, for actually manufacturing it. And we’re not even going after manufacturers, either, but lone wolves, individuals.
Again there, if you're a business he's fine. If you're an individual, it's banned. He even slips and admits he want to criminalize the sharing of the information.
So we’re talking to stakeholders, and working to create a distinction between that lone wolf and legitimate manufacturers of plastic clips.
Make no mistake: the forces working to ban private ownership of 3d printers are already moving against you. The bogey man of undetectable guns is simply a convenient way to get people on board with the first step of restriction. Once that's in place another big-business congressman will come back and say, "Poor GM is losing money because it can't sell overpriced factory parts because people are just printing them. Ban all private 3d printer ownership!"
The only thing in question is how many people will be fooled and take up the torch and pitchfork against 3d printed guns, not realizing that they're working against their own desire to have privately owned 3d printing technology. As is commonly the case, the fight for gun rights is only a microcosm in the larger fight for natural and civil rights. You want 3d printers? You're going to have to fight to protect 3d printed guns. You want marijuana legalized? You're going to have to fight for private ownership of machine guns. You want to continue to be free from poll taxes? You're going to have to support repealing the NFA.
Issues of law and politics don't each exist in separate vacuums.
