3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file
3D printing is the opposite ofsubtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine.
The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created
3D printing enables you to produce complex shapes using less material than traditional manufacturing methods.
