The world’s first fully 3D-printed gun is now a reality, confirmed with a test firing that demonstrates it can be deployed without damage to the body of the gun. Dubbed the Liberator, the one-shot pistol is formed from sixteen pieces printed in ABS plastic with a Stratasys Dimension SST printer. The only exception is a single nail, which is used as a firing pin. The Liberator was created by 25-year-old Cody Wilson, a University of Texas law student and the founder of non-profit group Defense Distributed, which has made the 3D-printable CAD files available for download. See a test firing in the video below.
