窩洞内部に生体材料粉末を選択的に積層造形する技術を確立するため，造形に適した生体材料，粉末堆積方法，レーザー照射条件を検討し，セラミックスや歯質への造形実験を行った．その結果，β-TCP粉末が最も積層造形に適し，造形物の下部にレーザープロファイルに起因した熱影響層が形成され，熱影響層を低減させる条件選定が必要なこと，造形物の溶融・凝固幅がレーザー条件から算出でき，適切な選定によって積層造形できることなどを明らかとした．赤外線輻射温度計による温度計測では，粉末表面からのプルーム光を受光して正確な計測が困難であるため，温度計の受光波長域を変更した測定手法を確立する必要があることがわかった．
In order to establish the additive manufacturing technology of biomaterial powder on the prepared cavity of human tooth, various biomaterial powders were built on the substrate and the building conditions were optimized. The depositing method of biomaterial powder on the substrate was also evaluated. As results, the biomaterial powder had cohesive property and was deposited on the substrate by coating the suspensions which were including the biomaterial powders. The beta-TCP powder was the suitable for the building on the substrate when the Yb:fiber laser was used. The aspect of built structure was controllable by laser conditions. The heat-affected zone was formed around the built structure, therefore the laser conditions to prevent the HAZ should be selected. When the temperature during laser beam irradiation was measured by the two-color pyrometer, it was difficult to obtain the temperature of biomaterial powder due to the gas plume which was formed from the laser irradiated area.
