| Outline of Final Research Achievements |
Utilizing a 3D printer that can build carbon fiber reinforced plastic (CFRP), which is used in aerospace applications, we have optimized the 3D printing path for the external shape and the interior of the structure. This process enables optimal design that takes full advantage of CFRP's characteristics, making it possible to create a lighter and more efficient CFRP structure.
