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.

It's kind of funny that Americans with all their guns seems to have a more tyrannical government than countries with fewer guns but a lot more political engagement from the population.

That's because most Americans have added two boxes to the four boxes of liberty: the ice box and the idiot box. And they seem to have stopped using the four others.

I do know something about guns and about metal machining and fabrication work. Making a Sten is dead-simple. Heck, I've got the plans.
You're correct that between the staggering number of guns that already exist in the US (and the majority of rifles & shotguns never having been registered) combined with the ease with which a gun that's at least good enough to get an enemy's gun is to make conventionally, it seems pretty impractical in the short term.
However, there's "simple" for some people and then there's "simple" for everybody else. It's dead-simple *IF* you have a lathe, drill press, sheet metal brake, and maybe a mill depending, along with multiple other ancillary tools and pieces of equipment like an arbor press.
*AND* you *also* have the requisite training, skills, & experience to operate that fabricating equipment well enough to produce more than a modern-art piece or a way to assure that you never need worry if you lose one of your mittens and/or your sunglasses. It's not a trivial skill set in the least.
The difference here is that you basically only need the printer instead of a pole-barn full of expensive machine tools, plus you don't need any advanced machining & metal fabrication skills or training to fabricate high-quality components.
The printer/software and the plan file supplies the majority of the training, experience, and skills otherwise necessary, while replacing multiple expensive pieces of metal working & fabrication equipment while also requiring less space. More like residential garage/shed/basement-size instead of pole-barn size.
A metal printer would also be a much more practical solution in the city. The printer is also far more portable than a bunch of machine shop equipment. It can be relatively quickly moved between locations and concealed compared to normal tooling.

I agree. However, I'm hopeful that people are beginning to wake the hell up. I haven't seen the current levels and breadth of dissatisfaction and anger with government since the '60s/'70s, nor anywhere near the current numbers of people who seriously think the government needs to spend less and have fewer powers, and are actively getting involved and doing something about it.
When was the last time you remember *this* happening?

There may yet still be hope. Especially if you consider it was only about 10% of the colonists at the time who were actively for the US Revolutionary War and independence from England.
Can we scrape up 10% with a brain and a spine these days? Who knows. We'll find out, I guess.
Maybe the concept of free men governing themselves by common agreement dies here forever, technology guaranteeing the jackboot continues forever grinding the human face underfoot.
Maybe humans need another few 10, 20, or 100s of thousands...maybe even millions...of years of evolutionary advancement before mankind is ready to leave kings, dictators, tyranny, and authoritarianism behind us.

There are times when I think the whole 2nd Amendment thing may be doing us more harm than good. We don't take political action when we should because if things get too bad we can just haul out our guns.
Except that by the time guns are the best or only solution, we've already lost pretty much everything anyhow. And who (aside from fantasists) really want a life that's basically nothing but guerilla warfare against tanks and drones?
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.
(But I can cite several events where voting ballots in the hands of little people made the U.S. government to either change policies or itself.)
The freedom of expression, used by people willing to suffer the consequences of standing up to tyrants, their ability to inspire millions of ordinary people to rise up against tyranny is what creates a thriving democracy with great standard of living. That is when warrior wannabes like you strut around claiming to be the cause. You are the effect, not the cause, of the first amendment.
Trying your "second amendment solutions" against a lawfully elected government of the USA is rebellion, and it is constitutional for the government to put such insurrection using any means necessary. If the government is restrained it is because of the first amendment rights of people who would speak up against heavy handed tactics by the government. Definitely not because of your puny little glocks, brownings or bushmasters. Our army had been battling AK-47s and IEDs for ages now buddy, you don't stand a chance against our army. You are able to trash talk, only because we restrain our government against taking overt and open actions against US Citizens.
Just look around you. People who used guns to overthrow tyrants became tyrants themselves. People who spoke out and inspired ordinary people to rise up against tyranny created enduring democracies. Only in such democracies crazy wingnuts are able to run around waving their guns thinking they somehow are the protection against tyranny.
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
With this technology, guns will be a side show. Yes, people will make them and there will be much bloviation about that, but the real impact will be on local economies.
Open any phone book or Google for any city, "machine shop"; there will be hundreds. They are the foundation of any kind of manufacturing economy. My company deals with at least 20 different shops, parceling out work to meet shipping deadlines and lower costs. When this technology matures to the point where it is as ubiquitous as a CNC mill or lathe, you will see turn around times crash and labor shift from skilled machinists to skilled CAD engineers (good or bad...you decide). It's conceivable that the actual making of a part becomes almost a lights out operation.
Hang on to your hats, this will be a game changer in the world economy.
When Fascism comes to America, it will call itself Anti-Fascism, and tell you to give up your guns.
