| Outline of Final Research Achievements |
In order to shape zirconia ceramics by additive manufacturing, it is necessary to heat the material in an isotropic manner. Although the electric furnaces are used in general it takes a long time to raise and cool the temperature of the material. In this study, a electric conducting material is arranged around a zirconia ceramic, and the material is heated rapidly by induction heating. The temperature was raised indirectly by raising the temperature of the surrounding material. In addition, despite the rapid temperature increase, no cracks or fractures occurred.

| Academic Significance and Societal Importance of the Research Achievements |
ジルコニアセラミックスはこれまで電気炉で焼成することが通常であり，焼成に7時間程度かかっていた．ジルコニアセラミックスの積層造形法を確立することを目的とする中で，クラックを生じずに高速に加熱する方法を提示することができた．本方法を用いることにより今後ジルコニアの積層造形技術の確立を目指すことができると考えられる．
