3D printer itself had been used to create a prototype

The order came to be sold at mass retailers lower prices advances 3D printer itself had been used to create a prototype, such as the automotive industry originally, enters the 2010s, it began to hit the general public. Laws and regulations of the past, those "things" is not a tangible object tangible object, such as the 3D data is "information" but it is defined to be clearly separated as a typical, crack down on manufacturing, possession and distribution of firearms as a tangible object it was however, since the boundary between the two has become blurred in the evolution of technology, such incidents have come to occur.

Also until then, firearms produced in 3D printer part of the parts had been made​​, but by the organization called Defense Distributed in USA, all parts of the world's first named Liberator is capable of producing pistols by the 3D printer in 2013 data has been published. In response to this, in the same organization, the State Department is doing the notification so as not to perform the public of the blueprint as there is a risk of violation of the International Traffic in Arms Regulations which defines the export regulations of firearms. In Philadelphia USA, to the end of 2013, regulations for the manufacture of gun using a 3D printer began, but legal reform that has received the firearms manufacturing by 3D printer still has been done in most countries at the stage of 2014 no.

To begin with, gun itself made ​​with resin is dangerous for the user, regulation is desired also from this point of view, but the design files published a similar succession of Other from Liberator published immediately after, one-shot only could not launch initially also 3D printer made ​​firearms was an improved version that allows multiple departure fire immediately and appeared, I have evolved rapidly.
