European officials have noted that producing a 3D-printed gun would be illegal under their gun control laws, [26] and that criminals have access to other sources of weapons, but noted that as the technology improved the risks of an effect would increase. [27] [28] Downloads of the plans from the UK, Germany, Spain, and Brazil were heavy. [29] [30]
The issuance of a drawing from the engineering/design activity to the production activity. In other words, the event when a draft becomes a completed, official document.

Department of Justice officials announced national efforts Friday to crackdown on 3D-printed devices to convert guns to fire fully automatic.
A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets introduced by Sir John Herschel in 1842. [1] The process allowed rapid and accurate production of an unlimited number of copies.
The classic reproduction methods involved blue and white appearances (whether white-on-blue or blue-on-white), which is why engineering drawings were long called, and even today are still often called, "blueprints" or "bluelines", even though those terms are anachronistic from a literal perspective, since most copies of engineering drawings ...
A competent machinist should have a well-developed mechanical aptitude, the ability to correctly use precision measuring instruments and to interpret blueprints, and a working knowledge of the proper parameters required for successfully utilizing the various tools commonly used in machining operations. CNC (computer numerical control) is the ...
