Additive manufacturing including 3D printing technology is considered to have a strong impact as much as to invoke Third Industrial Revolution. In order to realize the potential of the 3D printing technology and thus result in high value-added industry, a significant progress in the technology is required. Higher precision printing with higher speed, variability of printing materials and more flexible printing technology should be the near future challenging issues. Further progress would require a cluster printing environment composed of the advanced printers to meet variable requirements of manufacturing. We proposed this concept as the ‘3D Printing 3.0’ technology and will launch a national research program in Korea (2014 ~ 2023). For the ‘3D Printing 3.0’ era, we plan to develop advanced 3D printers in four technical categories: Printings for Hierarchical Structure Materials, Printings for Bio-devices, Printings for Convergence Devices, Printing for Advanced Die and Parts. Furthermore, these advanced printing technologies will be integrated into the cluster printing environment. The environment is based on the platform to provide both hardware and software for manufacturing functional materials and devices. Details of the strategy will be discussed.
