Perils of 3-D printers

The successful test-firing of Liberator, the world’s first 3-D printed plastic gun, has raised a legal storm. You can print this gun at the comfort of your home, sneak it past security in airports and malls. If a crime is committed using it, can it can be traced? The answer to the question remains open.

Cody Wilson, the 25-year-old founder of Defense Distributed, the pro-gun lobby group behind the Liberator, bought a $8,000 3-D printer from eBay and used it to pour layers and layers of high density plastic to mould the gun. The 3-D printers, currently available in the US market, which cost a little over 1000 dollars, would not be able to print it. But give the technology 10 years, there is a good chance that it will improve and become ubiquitous like your microwave. You would be able to print an AK-47 at home if you want to.

Defense Distributed put the design to make the gun online. There was a link on its site but the actual download was from Kim Dotcom’s Mega storage site. The file got downloaded 100,000 times, before the US government acted and got the link removed from the Defense Distributed web site. Kim Dotcom also subsequently removed the design. A US senator has introduced a bill to outlaw printed 3D guns. But it is hard to control any technology that comes in the form of software and links up to internet for distribution. Liberator designs are now available on Pirate Bay where it is being shared furiously. The music industry has fought the pirate sites ferociously for over a decade. But a victory is nowhere in sight.
