| Outline of Final Research Achievements |
In recent years, additive manufacturing has been introduced in earnest in various fields such as aerospace, automobiles, machinery, construction, and medical engineering. The main reason is that if the optimum structure is designed and manufactured by taking advantage of the free shape, which is the greatest advantage of additive manufacturing, a significant weight reduction can be expected. However, the design that takes advantage of the additive manufacturing requires a high degree of knowledge, and the hurdles are still high. In order to produce such highly designed structural products, research and development of topology optimization methods premised on additive manufacturing are indispensable. In this research, we have developed a highly versatile topology optimization method that makes this possible.
