Tsumori-Tsushima Lab (Aerospace Materials Engineering)
Machine-translated · View original
The lab explores new materials for aerospace and the methods for processing them.
AboutAbout the lab
Interesting, fun, and exciting.
The Tsumori-Tsushima Lab studies structural and functional materials for aerospace, and how to process them.
The lab works on developing 3D printing technology, microfabrication using nanopowders, and actuating structures made of soft materials.
Recently, the lab has also put effort into research inspired by living things (Bio-inspired Engineering).
The lab also conducts analytical and experimental research that considers aerodynamics and structures together.
Key terms
- 3D printing
- A technology that produces complex three-dimensional objects from CAD data.
- 4D printer
- A printer that adds a further dimension, movement over time, to the three-dimensional objects it prints.
- Magnetic rubber
- A soft material made by mixing magnetic powder into rubber so that it responds to magnetic fields.
- Micro-imprinting
- A process that presses a mold with fine patterns onto a material to transfer the pattern.

ResearchResearch themes
The lab studies new materials and how to process them, including 3D printing, microfabrication, and soft materials. While advancing applications to aerospace structures, it also puts effort into research that draws on living things for clues.
*Illustrative image3D Printing and 4D Printers
The lab is advancing research on printing metals, ceramics, and flexible materials such as rubber and gel, and is making this compatible with combining materials (multi-material printing). It is also developing a new type of 4D printer that uses magnetic rubber.
*Illustrative imageMicro-imprinting
The lab is developing a technique to easily transfer fine structures even onto “hard” inorganic materials such as ceramic nanopowders and metal powders. Surface patterning can change wettability and improve antifouling and anti-icing performance.
*Illustrative imageFlexible Materials That Respond to Magnetic Fields
The lab makes soft materials that respond to magnetic fields by dispersing magnetic powder in rubber or gel. A magnetic field is applied before curing to induce a directional bias in the material. The listed themes are the fabrication of biomimetic structures such as artificial cilia, and soft robots made from tough gel materials.
*Illustrative imageBiological Models (Learning from Living Things)
Within biomimetics, the lab attempts to extract mechanical engineering functions at a somewhat macro level. The themes are the folding and unfolding of beetle hindwings, stress transmission through roots, and the reproduction of biological surface functions through imprinting.
