Five 3D printing myths

The first conviction for 3D printing a firearm was recently reported in London, not long after 3D printed masks were used to trick face recognition. Although 3D printing processes vary widely, including melting metal powder with lasers or hardening liquid plastic "ink" with ultraviolet light, most people tend to think of 3D printing desktop machines that melt spools of plastic. Since these are often built or designed by enthusiasts, they are very affordable, with some models costing under £200. We research the realities of 3D printer usage by businesses and consumers – and so can dispel some of the most common fears around 3D printing. Designs for a "gun" that could be produced on a desktop 3D printer were first shared on the internet around 2013.
