At-home 3D printing is on the rise, and what was once just a lofty promise is now a reality. More and more hobbyists are acquiring affordable printers, such as the Makerbot Replicator 2 and the RapMan Universal 3D (single/dual head) printer, to manufacture just about everything from toys to working clocks.
Some hobbyists have used these printers for fast-prototyping items that are controversial -- or even deadly. It comes as no surprise that some would attempt to replicate weapons systems (or at least parts of them) in an effort to create a fully functional gun. It's not exactly clear who was the first to fabricate a firearm using a 3D printer, but one example that has garnered global attention is "Have Blue," who designed an AR-15 lower receiver (converted to fire .22 ammunition), using a CAD file in the SolidWorks file format that is openly available from CNC Gunsmithing.

After a few modifications to the original file, he set to work fabricating the receiver using around $30 of ABS filament fed through his Stratasys printer. After prototyping a small-scale model, he fabricated the full-size receiver and used it to fire 200 rounds without catastrophic failure. The proof of concept of manufacturing a 3D-printed weapon was a complete success. Now the door is open for others to try their hand at the home weapons manufacturing business.
A group of hobbyists (most of them college students) have banded together to form a company known as Defense Distributed to expand on the 3D-printed weapons systems and provide open-source software to anyone who wants it. Defense Distributed began its quest with the Wiki Weapon Project, which aims to provide all the necessary CAD software for manufacturing plastic firearms using any 3D printer. The group expanded on Have Blue's AR-15 to prove the concept of building weapons with a printer. However, instead of testing Have Blue's .22 conversion build, the group went ahead with an AR-15 conversion in 5.7x28FN, which has more firepower than a .22 but provides less pressure than the standard .223 round.
The group printed the lower receiver using Objet ABS-like filament piped through a Connex 3D printer. The printed rifle fired six shots before breaking. Apparently, the receiver's threads couldn't handle the pressure and snapped at the buffer-tube connection. The group is now looking for funding and a federal firearms license to get its project off the ground.
The problems with 3D-printed firearms aren't limited to catastrophic failure. (It takes only one bullet to kill.) There is also the issue of legality. No federal laws address manufacturing weapons with 3D printers, so anyone owning a printer could make a weapon -- even if they're not allowed to own one. The ATF considers the rifle's lower receiver as the firearm; anyone can purchase the upper receiver, barrel, etc.
The 1988 Undetectable Firearms Act prohibits the manufacturing or possession of guns that can't be picked up by airport metal detectors. This creates a loophole for hobbyists. Firearms typically require metal parts (barrel, springs, bolt, etc.) to function, and those parts can be detected. However, some companies don't want to take any chances. Defense Distributed's first attempt at funding in September through Indiegogo ended in disaster; Indiegogo froze DD's account and sent the $20,000 it raised back to the backers. In October, Stratasys terminated the group's 3D printer lease and seized the equipment from a member's home.
Like it or not, the seed of printing weapons has been planted, and the idea is sure to gain momentum through hobbyists in the near future -- until federal laws are enacted to gain control over the issue. It's only a matter of time before a printed weapon is used in a crime. Then all hell will break loose.
The media is full of dire warnings about 3D Printed weapons, and everyone is calling for new laws to address the issue. It is ridiculous to treat this as anything new, when this process cannot do anything that cannot be done using other methods which are readily available. Fully functional firearms can be, and have been, constructed from back-yard castings, CNC milled parts, and even hammered out of sheet stock.
I know people need licenses to make certain parts in guns, in some states. I have to admit, as a machinist, I would not want to report everything I am working on in my garage...
Cabe, You bring up a very good point about regulation. It seems as though if all eyes are on a subject, say drugs, then the offenders become more active in trying to beat the system. So, if there is no regulation (attention), then maybe the offenders will not attempt to use 3D printers for wrong doings. It may just work.
Yes, Boston will probably result in more rules. But you have to then wonder, since we now know that the FBI provided the bomb used in the 1993 WTC crime. The paid informer, Emad Salem taped the conversation where the FBI admited their involvement. So we can expect more attacks whenever there is a push for more regulation.
Government should not regulate weapons or be involved. Not only is the genie already out of the bottle, but government is the main reason weapons are necessary in the first place. If any individual does not have the right to make weapons, then who does? Can't be the government because government only acts as an agent for individuals, and has no authority of its own. To attempt to make illegal what is so easily done, is just douible speak. It makes no sense, and it makes individuals subordinate to government, which is backwards in a democratic republic.
It's not a good thing when a government wins an arms race against the private sector it's supposed to "serve". It's also not good when laws punish the law-abiding more than the lawless. I'm having difficulty trying to think of a gun "restriction" that didn't further skew both of those imbalances.
If the social contract otherwise known as the U.S. Constitutiion were to ever become binding between its clients again, we'd find that most "laws" restricting access to guns are a violation against that contract.
Yes, there are consequences to liberty, but the consequences of not having it have been far more dire for millions of people before us.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
