Outline of Research

In this project, we use the directed energy deposition method to conduct research and development in metal 3D printing. In addition, we use cold spray 3D printing technology to conduct fundamental research on the fabricating of alloy parts.

Research Purpose

Our objective is to establish metallurgical principles such as the microstructure formation mechanism in the two types of metal 3D printers which can be used for large parts: directed energy deposition and cold spray. We also aim to establish the basic technologies for developing new materials using these technologies.

Expected Effect

Unlike powder bed fusion, which is good for high-precision manufacturing of small parts, directed energy deposition and cold spray can be used for large parts. Therefore, by establishing the metallurgical principles of these two methods, it will be possible to use them with various materials and develop new materials using metal 3D printing technology.
