3D printing is the computer-controlled, layered construction of three dimensional pieces of work. The construction takes place using CAD files and follows given designs and measurements. Typical construction materials are, amongst other things; synthetic materials, artificial resins, ceramics and metals. The field of application for 3D printing is extensive; it is used primarily in industry, research and the commercial and domestic sectors. However, in the art world and many other sectors, 3D printing is no longer being discounted and is enabling new possibilities and opportunities in projects large and small alike.
