3D printing has found its place in this world. It is a production technique that converts a digital file into a tangible, three-dimensional object by building it up from layers. Everything starts with an idea being developed in a computer program. The digital design is prepared for and sent to the 3D printer, which builds the object layer by layer. How this is done, can vary significantly depending on the 3D printing process being used.
In the past, 3D printing was known as Rapid Prototyping because it was mainly used to design prototypes. Nowadays, 3D printing is known as Additive Manufacturing, which makes it clear that something is added or built up, whereas with other production methods - such as laser cutting - things are cut away.
