Development of Manufacturing Technology for Innovative Apparatus and Innovation Society from Central Japan
Shorten processing and assembly process by establishing multi-scale / multi-material manufacturing technology- Research institute
- The Japan Society of Mechanical Engineers, Nagoya University, Nagaoka University of Technology, University of Fukui, FAIN-Biomedical
Background
Additive manufacturing by 3D printers has excellent potential to create a revolution in manufacturing process. In contrast, it represents a credible threat to the fabrication and assembly processes which Japan is good at because the printing technology can skip some steps in the process and shorten the process time.
In this theme, we are working on establishing multi-scale, multi-material manufacturing technology which enables us to shorten the fabrication and assembly processes (Figure 1). Conventional manufacturing technology is inadequate to fabricate multi-scale and multi-material structures, namely, multi-scale, multi-material manufacturing technology needs to attract diverse players from a wide range of fields and industries.
Goals
