3D printers seem to be all the rage these days, and for good reason. They are freaking awesome, and they’re set to change the way we produce things in the future. Did you know that you can get a “cheap” 3D printer for your home (I use the word cheap loosely of course…I mean cheap relative to what’s out there). You don’t want to be the last one of your friends to own one of these revolutionary gadgets. The Makerbot Replicator 2 3D printer (above) has a resolution of 100 microns, 410 cubic inch build volume, and a sturdy steel frame. All you have to do is fork out about $2,000, learn how to use it and you could be well on your way to making your own guns in no time.
