Industry 4.0 is the recent move into intelligent technology automation. In this new era the use of modern skills of Additive Manufacturing within the context of information technology integration plays an important role in industrial economic competitiveness. This short review provides a basic understanding of the role of 3DP technology in the Industry 4.0. As can be seen, there's no doubt that 3DP technologies are leading to the next major industrial revolution. Due its versatility the Additive Manufacturing plays a key-role in the Industry 4.0, saving time and costs, being decisive for process efficiency and reducing its complexity, allowing for rapid prototyping and highly decentralized production processes. Currently, more and more industrial segments are adopting AM. The smart factories of the future have all processes interconnected by the Internet of Things, incorporating greater flexibility and individualization of manufacturing processes.
