“Alright. One…two…”

Before “three” arrives, a shot reverberates across the overcast central Texas landscape. A tall, sandy blond engineer named John has just pulled a twenty-foot length of yellow string tied to a trigger, which has successfully fired the world’s first entirely 3D-printed gun for the very first time, rocketing a .380 caliber bullet into a berm of dirt and prairie brush.

He hurries over to examine the firearm bolted to an aluminum frame. But the first to get there is Cody Wilson, a square-jawed and stubbled 25 year-old in a polo shirt and baseball cap. John may have pulled the trigger, but the gun is Wilson’s brainchild. He’s spent more than a year dreaming of its creation, and dubbed it “the Liberator” in an homage to the cheap, one-shot pistols designed to be air-dropped by the Allies over France during its Nazi occupation in World War II.
