The lab studies additive manufacturing, building functional parts with 3D printing.

AboutAbout the lab
Stacking material to make new parts.
Niino Lab studies the processes and applications of additive manufacturing, also known as 3D printing.
The lab builds functional three-dimensional shapes and shapes made of multiple materials, aiming to create new functional parts and mechatronic parts.
Much of its research uses laser sintering, in which a laser melts and solidifies polymer powder.
The lab is located in the Institute of Industrial Science, and it belongs to the Department of Precision Engineering in the Graduate School of Engineering.
Key terms
- Additive manufacturing
- A manufacturing method that adds material little by little to turn a shape designed as data into a physical object. Also called 3D printing.
- Laser sintering
- A method of building shapes by repeating a cycle of spreading a thin layer of polymer powder and using a laser to melt and solidify only the necessary areas.
- Tissue engineering scaffold
- A material used as a scaffold in regenerative medicine when growing cells to create tissues or organs.
ResearchResearch themes
The lab aims to create new functional parts by using additive manufacturing (3D printing) to build functional shapes and shapes made of multiple materials. It studies both how parts are made (processes) and how they are used (applications).
*Illustrative imageLaser sintering at low temperatures
Normally, the powder is heated to near its melting point to prevent warping during building, but this limits the materials that can be used and makes it difficult to reuse the powder. The lab studies low-temperature building, in which the preheating temperature can be chosen freely.
*Illustrative imageBuilding high-performance plastics
Super engineering plastics have high melting points, and processing them normally requires special equipment with high heat resistance. The lab studies methods to process these polymers using low-temperature building.
*Illustrative imageBuilding polymer and metal in a single step
There are almost no methods that can build materials with greatly different melting points, such as polymer and metal, in a single process. The lab studies a method that combines a technology called LDS with laser sintering to build parts in which metal and polymer are integrated.
*Illustrative imageScaffolds for regenerative medicine
In collaboration with the Sakai Lab in the Graduate School of Engineering, the lab uses laser sintering to build tissue engineering scaffolds made of biodegradable polymer, and studies culturing organs that are relatively large and have fast metabolism.
