#4 The Ability to Print Anything

3D printing technology allows us to create practically any 3D object, but this capability can also be used in harmful ways. As 3D printers become more affordable and ubiquitous, it will be harder to control the printing of weapons, including guns, because anyone can download an algorithm and “print” whatever they want, right in their home.

Regulation and tracking of 3D-printed guns are difficult because there are no serial numbers on these weapons, so they represent a growing threat. In October, British police made a large seizure of 3D-printed firearm components, in a suspected makeshift firearms factory in London.

The fear is that extremists and criminals will get their hands on these unregulated guns as they move into the mainstream.
