SAN FRANCISCO – *Downloading a gun's design plans to your computer, building it on a three-dimensional printer and firing it minutes later. No background checks, no questions asked.

Sound far-fetched? It's not. And that is disquieting for gun control advocates.

Rep. Steven Israel, D-NY, said the prospect of such guns becoming reality is reason enough for the renewal of the Undetectable Firearms Act, which makes illegal the building of guns that can't be detected by X-ray or metallic scanners. That law expires at the end of 2013.

At least one group, called Defense Distributed, is claiming to have created downloadable weapon parts that can be built using the increasingly popular new-generation of printer that utilizes plastics and other materials to create 3D objects with moving parts. University of Texas law student Cody Wilson, the 24-year-old "Wiki Weapons" project leader, says the group last month test fired a semiautomatic AR-15 rifle -- one of the weapon types used in the Connecticut elementary school massacre -- which was built with some key parts created on a 3D printer. The gun was fired six times before it broke.

'Last month a group of kids used a 3D printer to actually manufacture key parts of the AR-15 and fire six bullets.'
- Rep. Steven Israel, D-NY

]Though no independent observer was there to verify the test, a short video clip showing the gun firing and breaking was posted to YouTube. Federal firearms regulators said they are aware of the technology's gun-making potential, but do not believe an entire weapon has yet been made.

"What's chilling is that last month a group of kids used a 3D printer to actually manufacture (key parts) of the AR-15 and fire six bullets," Israel said. "When the (act) was last renewed in 2003, a gun made by a 3D printer was like a Star Trek episode, but now we know it's real."

Even with gun control pushed to the top of the national political conversation, Wilson is steadfast about reaching his goal of making a fully downloadable gun. This weekend, he and his partners plan to print four new lower receivers -- the segment of the gun that includes the trigger, magazine and grip. He keeps three of these AR-15 parts -- one black, one white and another green - in his tidy student apartment in Austin, TX.

While saddened by the Connecticut mass killing, Wilson said Thursday that protecting the right to bear arms by giving everyone access to guns is more important in the long term than a single horrible crime.

"Clearly what happened in Connecticut was a tragedy," he told The Associated Press. "Still, by affording the Second Amendment protection, we understand events like these will happen."

He said he discussed with his partners whether they should suspend their effort, and they all decided it was too important to stop.

Wilson acknowledged there still are many technical hurdles to creating a complete gun from a 3D printer and provided no estimate on when his goal might be reached.

Special Agent Helen Dunkel of the federal Bureau of Alcohol, Tobacco, Firearms and Explosives, which helps enforce gun laws, said the agency is familiar with Wilson's project. She didn't offer an opinion but noted there is nothing illegal about making many types of guns at home. Exceptions would be high-powered weapons like machine guns and those not detectable by airport scanners.

Advances in 3D printing technology are fueling Wilson's goal. The printers were developed for the automobile, aerospace and other industries to create product prototypes from the same hard plastics used in toys like Legos. Hobbyists mainly use the printers to design Christmas ornaments, toys and gadget accessories.

Prices on the machines have fallen as the consumer market grows, leading to a surge in interest from people in the so-called "maker" scene. Low-end 3D printers can now be purchased online from between $1,500-$4,000. The more high-end printers needed to make gun parts are still priced from $10,000 and up.

Stratasys Ltd. Of Eden Prairie, Minn., makes 3D printers. Shane Glenn, director of investor relations, said gun-making was never something envisioned for the machines.

"The gun issue is something that the 3D printing industry will have to address going forward," Glenn said.

Right now, most people interested in 3D printing rent time on one. There are a number of businesses and co-ops in major cities that allow access to the machines for a nominal fee. At San Francisco's TechShop, which features a 3D printer for its members, "assembling firearms is strictly prohibited and our staff is trained on that policy," company spokeswoman Carrie Motamedi said.

Wilson acknowledged his idea has met resistance from those active in 3D printing.

"The early adopters of 3D printing technology seem to be an educated, more liberal group who were against firearms to begin with," he said. Wilson said some are worried the gun project might spur regulations that will hurt or curtail their projects.

Early schematics created by Wilson's group were posted on Thingiverse, a Brooklyn, N.Y.-based website that serves as a hub for 3D printing aficionados. After the school shooting, Thingiverse took down Wilson's links.

The site's spokeswoman Jenifer Howard said its focus is "to empower the creative process and make things for good." Howard said Thingiverse's terms of service state that users cannot use the site to share content that contributes to the creation of weapons.

Wilson said the group has already posted the links on its own website.

Paul Saffo, a Silicon Valley technology forecaster who teaches at Stanford University's engineering school, said Defense Distributed's work carries on a long tradition of tech geeks using innovation to make a political point, in this case on gun control and Second Amendment freedoms.

"If you want to get people's attention in Washington, you say something. If you want to do it in Silicon Valley, you make something," Saffo said.

He said the technology exists now for a highly motivated group to make a plastic gun on a 3D printer that could avoid airport scanners. But the equipment is still too expensive for most people.

"Nobody right now needs to worry about the bright teenager making a gun on a printer in their bedroom," he said.

The ones I have seen done so far are pretty short lived. There is video of at least one breaking apart at the juncture where the threads are for the stock mount. Not sure what the technical name for that is..

The magazines are a pretty cool idea, but I would expect the feed lips to wear out pretty fast.

At least until better materials are developed.
 
We have a 3D printer in the office and I must say, it is impressive. We can even print a part which rotates on a printed shaft. A wheel rotating on an axle is a good example, no assembly just creative drafting. I think the materials will improve in shirt order, but in the meantime a CAD designer can work around the shortcomings and build something a bit different, but effective.

Moron doesn't realize the barrel, firing pin, etc. will still need to be made of metal and will be detectable.

The stupidity of your average legislator never ceases to amaze me.

This. The fear mongering about this is ridiculous. There are components of the gun that will need to be made of metal in order to function. As for people being able to manufacture guns on their own that can't be traced by law enforcement (no serial numbers), any metal shop can already do this if they are so inclined.

80% lower? You could probably get away with renting a PO Box and sending a money order to pay for one or two, if you really wanted to be off the grid for that particular item.
 
People who have never used a 3D printer or understand their real capabilities are hyping the hell out of this. Just wrote a blog on the topic "Can 3D Printers make Firearms?"

In July of 2012, Popular Science magazine reported that an amateur gunsmith by the name of Michael Guslick had created “a working assault rifle from a 3D printer.” Specifically, he used a Stratasys FDM system to produce the lower receiver of an AR-15* style pistol, modified to fire a .22LR cartridge. Guslick went on to test this same part using a .223 caliber upper receiver – a full-powered rifle round. So did he really make a “3D printed gun?”

The simple answer is no – he made a firearm that had a 3D printed plastic part, and plastic parts are nothing new on firearms: Springfield Armory conducted tests with plastic stocks during WWII, most firearms today have plastic parts. The caveat, however, has to do with the specific part he printed: the lower receiver of an AR-15 style action.

All firearms sold in the US require a unique serial number. For most firearms, the serial number on the frame or receiver becomes the firearm from a legal sense. The manufacturer of such products must be licensed by the federal government as a firearm manufacturer and the parts are carefully secured and tracked under penalty of law.

On most firearm designs, the frame or receiver is also the part that bears most of the various forces that result from a projectile being fired. But in the case of the AR-15, the lower receiver does not bear these loads. It carries the trigger mechanism, safety, an opening for the magazine, magazine release, and a threaded hole to mount the stock (the recoil spring assembly is inside the stock). The AR-15’s Upper Receiver carries the barrel and bolt. As a result, almost all the forces resulting from firing are contained by the upper receiver. But in terms of legal definition, the lower receiver is the gun.

There are many other firearms with substantial use of plastic. Perhaps best-known is the Glock pistol, widely used by Law Enforcement agencies in the US. The Glock has a polymer frame, magazine body, and several other parts. But the barrel, slide, and firing mechanism are all metal. Many other pistols from companies like Smith & Wesson, Sig Sauer and others also have plastic parts but like the AR-15, all the parts in contact with the cartridge when fired are metal.

In the meantime.

I think that guy has the right idea.

A gun machined out of a solid piece of delrin would be a better bet than 3D printing right now.

Until 3D printing can make a more durable plastic, you might as well invest in a CNC rather than a 3D printer.
