Research Abstract

Single point incremental microforming of metallic foils without using any die and mould has been developed as a flexible fabrication method of micro shell structures. The minimum size of a shell structure was 50μm in length. An aluminum micro shell structure was coated with hafnium oxide or titanium nitride and then, only aluminum foil of formed structures was etched selectively in a solution of potassium hydroxide to fabricate the micro shell structures of ceramics only.
