Additive manufacturing is a technology that in recent years has been evolving very rapidly and is revolutionizing the design and production concept of the manufacturing industry, but there are still several problems that prevent its rapid spread. The design of components with the aid of this technology is still based on a "trial and error" approach, which makes additive manufacturing a too expensive process, especially for small-medium industries. The Direct Metal Laser Melting which is a Laser Powder Bed Fusion process is characterized by a multitude of variables such as material, machine parameters and component geometry, so it is very difficult to know what the successful parameters is to adopt.
