Additive manufacturing AM or 3D printing has had a huge impact on numerous sectors at scales ranging from microfabrication to big area manufacturing size of meters. Many predict that it will soon be recognized as the technology behind the third industrial revolution. It is defined by the ISOASTM as the process of joining materials to make parts from 3D model data, usually layer upon layer, as opposed to subtractive and formative manufacturing methodologies. With additive manufacturing, parts of complex geometry can be built with a single machine operation and without any special masks, tooling, dies, or fixtures. Originally used primarily for fabrication of prototypes and models of design concepts, various additive manufacturing methods are presently capable of producing functional devices, components, and structures constructed from numerous types of materials.
