Background

In the manufacturing industry in Japan, structured functional materials / devices have high profitability and high profit margins, but it is expected that shortening lead time of development will become "key" in near future. Under this theme, we will tackle.

  1. Development of functional ceramic composite nanomaterials, and their high-concentration and high-performance ink (fluidic materials)
  2. Development of 3D manufacturing technology for fluidic materials by inkjet method (IJ)
  3. Shor-lead-time development of devices (artificial teeth, 3D Li batteries) made of structured functional materials by 3D printing technology and establishment of new innovation style.

It was difficult to shape the conventional ceramic materials at 3D manufacturing by inkjet printing, because highly-concentrated ink shows high viscosity. We are aiming to enable high concentration filling of ceramic materials by supercritical field hydrothermal synthesis and organic modification(Figure 1).
