3D printing (or additive manufacturing), that is the use of digital files, eg computer-aided design (CAD) models, to produce three-dimensional objects, is becoming increasingly big news. Special software is used to cut the digital model into layers and create a file, which is sent to a printer to ‘print’ a physical object. Instead of ink, other materials, such as molten plastic, or metal in powder form, are built up in layers and fused together at high temperatures to create the product. Exeter University has even used the process with layers of chocolate to create novelty edible products.
