折り紙は学問と産業の両面で近年大きな注目を集めている一方で、既存の折り紙構造の素材の多くは紙と剛体パネルに限られてきた。特に布は、人間の暮らしに欠かせない素材である一方で、折りたたみ時の面のたわみと折り目付けの困難さから、折り紙構造の造形には不適であった。そこで本研究では、布の上にPLA樹脂によるテセレーション骨格を造形することで、布の柔軟性と折り紙特有の自由度の低い変形を両立する構造を実現した。

Despite recent advancements in both academic and industrial fields, research on origami structures are mainly limited to rigid panels and paper. While textiles play an essential role in human society, they were inappropriate for fabricating origami structures because of the low rigidity of the textiles and the difficulty to keep the folding patterns. In this research, we realized textile-based origami structures by utilizing 3D-printed frameworks made by PLA resin. These structures enable low-DOF (Degree of Freedom) folding patterns and controllable rigidity of textile surfaces while preserving their flexibility.
