| Outline of Annual Research Achievements |
This research aims to clarify positive effects on additive manufacturing (AM) available in high gravity, such as high modeling resolution and efficiency with far surpasses conventional AM. This research presents the development of a high-gravity material extrusion (HG-MEX) system. This year, we developed the belt drive system for the rotating drum, and the ball-screw driven system for the stage. In high gravity, we introduced a controlled variable that can influence fluid dynamics within the material extrusion (MEX). This research evaluated the gravity-driven positive effects on MEX which is also the one of AMs, by building a combined machine of MEX and centrifuge. This research analyzed the characteristics of HG-MEX. The increased gravitational forces can improve process stability. With the high gravity system, we now have the capability to conduct experiments and simulations aimed at identifying improvement of fabricate. The experimental evaluations demonstrate that the application of high gravity can improve the shape accuracy and performance of the parts fabricated through MEX. The proposed method clarified that high gravity is a promising approach to enhance the modeling resolution and efficiency in the MEX.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The research went well basically, following my research plan. Until now, this research successful made high-gravity material extrusion (HG-MEX) system design, centrifuge design and manufacturing. Numerical simulation geometry of the model extruder from nozzle is established along with the material extrusion process. This research analyzed the effects of gravity on the material extrusion process from nozzle extrusion. We made fabrication of the developed material extrusion (MEX) system, the centrifuge demonstrate our commitment to advancing research in different gravity environments. The HG-MEX characteristics during filament fabrication are evaluated. The advantage of high gravity material extrusion was confirmed.

| Strategy for Future Research Activity |
And then, firstly, I am going to summarize current results and publish at least one paper. For the future work, I plan to build upon the foundation laid by our recent achievements and continue advancing our research in high gravity experiments. Improvement of the high-gravity material extrusion (HG-MEX) system. This research will explore more high-gravity condition, and analyze complex material extrusion (MEX) condition. More experiments such as sample mechanical performance will be done. This research will gather more data from the experiments conducted using the HG-MEX system and centrifuge system. This will allow us to further uncover the unprecedented advantages of HG-MEX, such as defect-free fabrication and improved surface smoothness.
