You can read the complete introduction of "The Liberator" which is a 3D-printed gun, over at Forbes. The video below is 28 seconds, showing the creator of The Liberator, Cody Wilson, hand firing his creation for the very first time.
On a blazing Saturday afternoon, Wilson returns to the remote firing range where he first tested the Liberator. None of his Defense Distributed compatriots have joined him this time–John the engineer is away at the annual meeting of the National Rifle Association in Houston. But Wilson is accompanied by his father, Dennis, a lawyer from Little Rock, Arkansas who has flown in to witness a historic moment: His son plans to fire a fully 3D-printed weapon by hand for the first time.Wilson has spent the last few days tweaking the Liberator’s CAD file and re-printing its barrel, hammer and body to realign its firing pin and solve the misfire issue. But he becomes quieter as the moment of testing approaches. His father asks how far it is to the nearest hospital: a 45 minute drive. We consider how to make a tourniquet if things go badly. “You guys are going to make me lose my nerve,” says Wilson, smiling nervously.
Everyone but Wilson falls back behind him. Wilson opens the case holding the newly-printed pieces and assembles them, then loads the gun and inserts ear plugs into his ears.
He inhales sharply, aims the Liberator, fires it, and then exhales, in quick succession.
“Outstanding,” says Dennis Wilson. “Congratulations, my son.”
Wilson visibly relaxes. He shakes his father’s hand with his own fully-intact digits. Later he’ll examine the gun and find no obvious signs of damage other than a cracked pin used to hold the barrel in place.
For a few moments, Wilson seems lost for words. His expression is hidden behind his sunglasses. Then he says the first thing that comes to his mind. “Well, there are going to be some changes around here.”
