Submission Statement:

>Experts are concerned about how fast 3D-printing technology is evolving, as several countries worldwide still do not have legal frameworks to prohibit or limit the creation of these weapons. “We are facing a serious threat if legal measures are not taken to control the production of printers and printing materials necessary for their use,” he said. “The software that allows for the production of these types of weapons should, as far as possible, be banned from the market,” he added, explaining that this could prove difficult because the weapons are often sold in parallel markets. It includes selling on the darknet and in closed forums that can be difficult for law enforcement to access.

>Although the production of 3D-printed weapons is currently limited to small arms and light weapons (SALW), it is expected that the capabilities of this technology and the quality of printing materials will evolve and lead to more powerful and sophisticated weapons. “There are already some impressions of weapons of a military nature with appreciable fire potential. The evolution of printing materials will impact the increasing sophistication and production of these weapons and the threat they represent,” the Interpol spokesperson added. Interpol urged “necessary measures” to stop the potential use of 3D-printed weapons for “illegal means.” “If this does not happen, it will be natural that the threat evolves towards producing increasingly sophisticated forms of 3D weapons that are more powerful and reliable, which poses increasing challenges to preventing and controlling their use in the future.”

>According to Interpol, “3D-printed weapons” can be categorized as fully 3D-printed firearms, hybrid 3D-printed guns and firearms whose frame is produced in 3D printing. “They can go from things like the Liberator, which is this single shot, entirely 3D-printed weapon that’s all plastic except for the firing pin and obviously the ammunition which might be able to shoot five to 10 times before it suffers a catastrophic failure, all the way to something called the FGC9, which, if built correctly, is essentially as lethal, as durable, as effective, and as accurate as a commercially purchased firearm.” Entirely 3D printed firearms are weapons on which all major components are printed, in some cases with only minor non-printed parts. These weapons have a “limited capacity of use due to the absence of metallic components and their fragile structure,” the international policing body told. Hybrid 3D Printed Firearms are weapons with printed elements used in conjunction with non-controllable metallic parts, such as springs and metallic tubes.

>3D-printed guns are illegal from the moment of creation because they lack serial numbers and are not submitted to any official test bench.
