Outline of Research

Research and development of additive manufacturing and powders suitable for 3D printing

Research Purpose

Research and development of 3D printing technology and powders suitable for 3D printing will be conducted simultaneously to optimize product modeling. We will explore the basic principles that contribute to the optimization of modeling conditions in the laser and electron beams used for 3D printing. We will also work on process analysis and the development of optimal mixtures. In addition, we will study the optimization of metal powders for 3D printing by analyzing their properties with the plasma rotating electrode process.
By utilizing the university’s equipment and receiving materials, research knowledge, and support from Chiba Lab, we will develop analysis and evaluation tools, simulation technology for 3D printing, and analysis and evaluation materials. We will study the metallographic design of 3D printed products by developing and manufacturing powders, and we will search for the best metallographic structures, including optimal metal processing and topology optimization.

Expected Effect

We will examine the basic principles for optimizing fabrication conditions in laser and electron beam 3D printing, analyze processes, and develop optimum mixtures. We will also analyze the characteristics of metal powders using the plasma rotating electrode process and develop and manufacture powders. Through these efforts, we aim to provide comprehensive solutions in the field of metalloid fabrication, including powder development and manufacturing, search for and evaluation of optimal metallographic structures, and design of 3D printed products that utilize optimal metal processing and topology optimization.
