3D printing is not as complicated as it might first appear. Users simply start by designing an object on an ordinary PC, which is then connected to a 3D printer - and voila.
The 3D printing process sees an object turned into thousands of tiny slices, which are produced from the bottom upwards in a method known as fused deposition modelling (FDM). These slices bond together to form a solid object. Each individual layer has the potential to be incredibly complex, which means 3D printers can even create moving parts including hinges or wheels.
