Engineers and designers have been using 3D printers for more than a decade, but mostly to make original types quickly and cheaply before they embark on the expensive business of tooling up a factory to produce the real thing. As 3D printers have become more able to work with a broader range of materials, including production-grade plastics and metals, the machines are increasingly being used to make final products too. More than 20% of the output of 3D printers is now final products rather than original types, according to Terry Wohlers, who runs a research firm specializing in the field. He predicts that this will rise to 50% by 2020.
