3Dプリンティング技術によるSOFC試作法の提案

抄録

In this study, basic experiments were conducted to apply a light-curing 3D printer that uses resin cured by a certain wavelength of light to the fabrication of solid oxide fuel cells (SOFC). When using this method, the volume fraction of ceramic powder mixed in the resin has a great influence on the feasibility of the molded object. The upper limit of the volume fraction to obtain a compact of the target size by 3D printer is 22%, and the lower limit of the volume fraction to obtain a compact of the target size by 3D printer is 22%. The lower limit of the volume fraction that can maintain the shape after firing is determined to be 20%. However, the fired compact is very brittle when the volume fraction is less than 20%, so further improvement is needed to increase the volume fraction.
