Additive technology is raising a huge interest in all industry sectors, due to its peculiarities compared to more traditional manufacturing processes. Some advantages typical to this technology include the possibility to generate ideally any shape and to reduce the number of parts required to obtain a given shape. In addition, there is no (or very little) waste of material since only what is actually needed is used. The more the technology gets used for critical parts, the more urgent the need for better knowledge of the expected performances becomes.
