What is 3D printing?

3D printing which is also called additive manufacturing is a process of making three dimensional solid objects from a digital file.

3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing or carving out a piece of wood, metal or plastic from a large piece with the aid of a chisel or milling machine.

In an additive manufacturing process, an object is created by laying down successive layers of material until the object is created. 3D printing enables one to produce complex shapes using less material in less time.
