Although it is not impossible to manufacture 3 dimensional structures by an Origami technique using conventional flat sheet, from the engineering standpoint, the range of producible models become confined for the complexities of the manufacture procedure. Therefore we try to use geometrically prescribed uneven sheet with periodical indents instead of a flat sheet to achieve an easy processing of 3D structures. By using such sheets, several geometrically simple structures such as rigid mast and plates were manufactured.
