The lab designs materials and processes for metal 3D printing through both computation and experiments.
AboutAbout the lab
Designing materials and processes through computation and experiments
The Materials Design and Process Engineering Lab studies materials that deliver the desired performance and how to make them, combining computer simulation with experiments.
Currently, the lab focuses on the solidification of metals that occurs in metal 3D printing (additive manufacturing), and works on controlling crystal orientation and size so that not only the shape but also the properties of the material are made as intended.
The lab also works on metamaterials, which exhibit properties that the substance does not originally have through the shapes given by 3D printing, and on research that contributes to sustainable development, such as recycling.
On the lab's website, it is introduced as the "Koizumi Lab."

ResearchResearch themes
The lab develops materials that exhibit desired properties, together with the processes to actually manufacture them, by combining advanced experiments with computation such as simulation and machine learning. Specifically, it works on creating new materials using metal 3D printing and the melting and solidification by lasers and electron beams used in it.
*Illustrative imageMechanism of grain refinement in Al-Si alloys
The lab investigates how grain refinement occurs in Al-Si alloys during metal 3D printing. Laser irradiation experiments and simulations have yielded results suggesting that unmelted Si particles serve as nuclei for solidification.
*Illustrative imageA digital twin for metal 3D printing
The lab is developing digital twin science methods, which estimate phenomena that are hard to measure directly through simulation combined with observational data. Aiming to understand the crystal growth specific to metal 3D printing, it is building the scientific principles for controlling crystal microstructure.
Optimizing build conditions without trial and error
The lab aims to make it possible to determine metal 3D printing build conditions without relying on trial and error. By finding the rules that link material properties to optimal conditions, and combining experiments and computation, it works to establish guiding principles for controlling material microstructure during the build.
*Illustrative image3D printing that controls both shape and internal microstructure
The lab aims for metal 3D printing technology that freely controls not only shape but also the internal microstructure of the material. It seeks to clarify the governing factors in microstructure formation and to build the academic foundation for optimizing the microstructure of each part.
