パーソナル・ファブリケーションは急速な技術の進歩により,身近なものとなってきた。ファブリケーションは新しい教育の現場でも注目されており、今後は一般家庭から社会までより拡大する分野と考えられ折り紙から着想を得た容易に立体構造を構築できる手法です。２つの帯状の紙を交互に折り込んでいくとバネ状の構造を構築できます。この手法は伸縮するだけでなく、展開図や折り方の手順を変えることで交互に折り込むという単純な工程で様々な形状を設計できます。提案手法では手軽に平面から立体を構築できるため、DIYから産業応用まで幅広い活用が期待されます。

In this study, we propose the design and implementation of a smart textile using conductive sequins produced by a 3D printer based on traditional sequin embroidery.
The well-designed conductive sequin smart textile, referred to as traditional sequin embroidery of various designs and diverse embroidery techniques, can break through the limitations of sequin fabric in its vertex modeling capability to create vertex-like sequins.
Using conductive and non-conductive resins, we printed out two types of sequins using a 3D printer1, which are then combined and embroidered using the traditional sequin embroidery technique. When a force such as a touch or press is applied to the conductive sequins, a signal generated from the circuit, which those sequins themselves are part of, will be sent to the computer. The computer can visualize the electric signals of this textile and sense the changes in the state of the textile.

This study proposes a method of fabricating jamming user interfaces using multi-material 3D printing. Through customized fabrication software, users can decide the properties of components of the interface, such as the size/shape of beads. The software automatically renders a membrane and an inner complex of beads after users decide the properties, which simplifies the manufacturing process of the jamming interface. Moreover, 3D printing allows the interface to have a double structure consisting of multiple rooms functioning jamming independently, which realizes a richer haptic experience. Finally, this paper describes the manufacturing process of the jamming interface using 3D modeling software/3D printing. It demonstrates the merits of this method with several applications, such as the haptic device and the shape-changing controller.
