3D Systems is a firm founded by Chuck Hull, who in a 1986 patent described a system he had invented for making three-dimensional objects as "stereo-lithography". It worked by using a beam of ultraviolet light to solidify a thin layer of liquid plastic, a bit like ink, and repeating the process by adding more liquid plastic. Other forms of 3D printing have since emerged (see box, next page), but they all work as an additive process, building objects up layer by layer. 3D printing was originally conceived as a way to make one-off prototypes, but as the technology is getting better more things are being printed as finished goods (a process known as additive manufacturing). One-off prototypes can be hideously expensive to produce, but a 3D printer can bring down the cost by a huge margin. Freed of the constraints of traditional factories, additive manufacturing allows designers to produce things that were previously considered far too complex to make economically.
