3D folded PrintGami: Transform passive 3D printed objects to interactive by inserted paper Origami circuits

Recent advances in 3D printing allowed end users to easily utilize desktop 3D printers. However, these printers mainly consume molten plastic, due to limited materiality in customer level. While high interests in creating interactive 3D objects with electronics are ubiquitous, commercial 3D printers have not yet provided adequate supports for integrating electronic components. On the other hand, paper as flexible medium has shown its possibility to be a channel to host interactive objects, enabling interaction triggered by users. In this paper, we introduce a process of integrating paper circuit into a 3D printed object, combining two universal fabrication techniques, 3D printing and paper crafting: 1) design a hollow 3D model, 2) construct circuits on the 2D planar cutout of this figure, 3) pause 3D printing to insert folded paper circuits in, and 4) resume to complete printing. We empower makers and tinkerers to employ pervasive technology to build interactive 3D objects without hacking machine, obtaining professional utilities, or buying expensive materials.
