In additive manufacturing processes the components are produced by a layered structure of the material. This contrast with traditional subtractive processes like turning, milling, drilling, etc. producing the final shape of a component by the removal of material.
This construction in layers makes it possible to produce very complex geometric shapes from a quantity of 1 to medium series productin in a simple and affordable way.
Therefore, additive manufacturing technologies are regarded as clearly the most important future key technology in the industrial production technology and are a central part of the campaign industry 4.0 .
