The technologies involved are innovative and the basic plan that represents the thrust of transformation is the concept of automation. Even the automotive industry is not an exception: in addition of the yet already consolidated mass production of automobile components as mature legacy of third industrial revolution, it is evolving to develop the capability specific replacement parts required on demand only when needed. This thesis work consists in the analysis and study of the already existing industrial additive manufacturing process and then propose a new production system capable of integrate two of the leading technology of the Industry 4.0: blockchain technology and additive manufacturing.
