3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. 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 entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual objects.
