What is 3D printing?

Also known as additive manufacturing, 3D printing is a process by which a three-dimensional product is made via a plotter that moves along x, y and z axes, adding material — commonly any number of plastics, polymers or metals — as it builds layer upon layer.

The process dates back to the early 1980s, and ongoing developments have added greatly to the types of material that can be used and the speed of the printers, although the latter are largely still too slow for mass production. Because designs can be easily changed without retooling a machine, 3D printing has become a favoured technology of industries where small numbers of specialized items are required, including medical and aerospace applications. In recent years, additive manufacturing has been used to print food, clothing and even houses.
