Secondo le previsioni del Wohlers Report, il mercato mondiale dell’additive manufacturing e del 3D Printing raggiungerà, nel 2017, i sei miliardi di dollari e supererà nel 2020 i dieci miliardi.
According to the Wohlers Report, the global market of Additive Manufacturing (AM) and 3D printing will reach 6 billions in 2017 and will exceed 10 billions in 2020. It is not a coincidence that the National Industrial Plan 4.0, also called the Fourth Industrial Revolution, which has been developed by the Minister for Economic Development and has been in effect since the first half of 2017, encourages the companies to use additive technologies through various tax incentives. Similar to what happened in the 1950s with the advent of CNC machines and, from the 70's to CAD / CAM systems, AM would likely completely overturn the production methods, also thanks to the possibility of customization and of production of complex components, optimized for their functionality without the limitations imposed by conventional manufacturing processes. This study aims, through a software analysis and simulation process, to prevent potential errors that may come out during the production process (such as internal residual stresses at critical points of the component being manufactured) and thus to avoid corrective actions and the consequent time and cost disadvantages. Besides, in the absence of a simulation process, the trial and error approach leads to many rejected parts, which are not compliant with the required standards. The first phase of the work focused on the production of calibration specimens with the SLM 280HL machine. This process involves the preparation of the job from start to the end (powder sieving, mounting / removing plate-recoater, cleaning). Once the specimens were obtained, they were used to calibrate the simulation software; in this way, the simulator can deliver results very close to reality. Then the work focused on the simulation of a mechanical component and on its production.
