Outline of Final Research Achievements

We researched a high-speed fabrication method to deform clay-like materials to create three-dimensional objects, in order to achieve high-speed three-dimensional fabrication in digital fabrication. We developed a device to control the deformable magnetic resin by mixing low-melting-point resin and iron powder and by using a linear actuator and a magnet. These results were published at SIGGRAPH2020. We also developed Floating Pixels, which displays arbitrary numbers on the surface of water. The magnetic spheres printed with magnetic resin are floated on the surface of the water, and multiple actuators with magnets attached are controlled from below to display arbitrary numbers. The work has been exhibited permanently in Singapore, and these researches have been presented at international and domestic academic and artistic conferences.

Academic Significance and Societal Importance of the Research Achievements

個々人に適した物品を多品種少量生産可能な新しいデジタルなものづくり環境として、3Dプリンタなどのデジタルファブリケーション技術が研究開発されている。しかし現在の３Dプリンタは多くの造形時間を要することや素材が繰り返し使用できない課題がある。本提案は、粘土状の素材を変形させて立体物を造形することで、立体造形の高速化を実現できる。また、研究成果は、立体製造技術に繋がる科学的な知見を得ることができ、今後のさらなる高速化、高解像度化、立体精度の向上に繋がることが期待される。
