Printing in 3D, also referred to as additive manufacturing, is a process of making three-dimensional solid objects from a digi- tal model. Accordingly, an object is created by laying down successive layers of mate- rial. It is distinct from traditional machining techniques （subtractive processes）, which mostly rely on the removal of material by cutting and drilling.
