In the last decades, most sectors, such as communications, engineering, images, and architecture have all experienced their own digital transition. The Additive Manufacturing technology is a technological process born from this evolution from analogue to digital processes. For this reason, it is now possible to apply Additive Manufacturing in order to make the operations more flexible and efficient. Additive manufacturing has actually been around for several decades, while it seems new to many. Although the terms ‘3D printing’ is wrongly used to discuss additive manufacturing, it is actually a subset of additive manufacturing. In the right applications, additive manufacturing delivers improved performance, complex geometries, and simplified fabrication.
