ABSTRACT

In the field of HCI, methods for creating morphing food have required the process of making sheets and cutting out the shapes by hand. In order to simplify the fabrication process and further expand the customization and design of shape-changing foods, we have developed magashi, a new method which enables users to design food in different shapes with intricate patterns by utilizing extrusion-based food printing and baking. With our technique, the printed food with mesh patterns can form into curved structures when baked. In order to realize this method, the material’s ingredients, printing patterns, and thickness were optimized to control the drying process of the material, consequently inducing it to bend upward or downward during baking. We also propose several applications for creating shape-changing food and cutlery in different shapes, patterns and curvatures.

我々は、射出成形による食品印刷と造形後の加熱・変形を利用して、複雑なパターンを持つさまざまな形状の食品を設計することができる手法「magashi」を開発しました。この手法では、平面パターンとして印刷した食品を焼くと、加熱とともに変形し曲面状の構造物になります。素材成分の調整、印刷パターン、および素材の乾燥プロセスの制御により、焼成時に上向きまたは下向きに曲がる設計を可能にしました。本手法を活かして、最中などの立体構造を持つ和菓子デザインへの適用や変形するカトラリーなど、いくつかのアプリケーションを提案しています。
