It’s true that 3D printing is coming on the scene like gangbusters. A few years ago 3D printers were used mainly in the manufacturing industry for rapid prototyping.
But now the industry has changed, the printers have gotten cheaper and a few people are starting to make guns from the 3D printing process. And we are talking about the kinds of hard plastic guns that could evade metal detectors at airports.
If you think this is far-fetched then check out what the Seattle Times has to say, “University of Texas law student Cody Wilson, 24-year-old ‘Wiki Weapons’ project leader for Defense Distributed, says the group last month test fired a semiautomatic AR-15 rifle – one of the weapon-types used in the Connecticut school massacre. Video posted by the group on YouTube indicates the gun was built with some key parts created on a 3-D printer and fired six times before it broke.”
And of course since this is leading edge stuff we are talking about here, there are no laws against doing this in the privacy of your own home.
Here’s a Youtube video that talks about 3D printing of guns: http://youtu.be/YqzJlBcCsow
