Approximately nine years have passed since the start of the global third 3D printer boom in around 2013. Looking around the world, 3D printing technology continues to evolve as Additive Manufacturing (AM) technology, and, as a new manufacturing technology in the digital age, it is expanding to the manufacture of not only prototypes but also actual parts. During the COVID-19 crisis, it is also attracting attention as an urgent on-demand manufacturing technology in disrupted supply chains. This paper will explain the trends of the 3D printer market and related technologies based on the latest information from all over the world.
