KiriInflate: Fabricating Cross-Scale Inflatables with Large-Magnitude Contraction and Tunable Stretchability for Tangible Interaction

We present KiriInflate, a rapid, precise, and accessible fabrication method for creating stretchable inflatables with Kirigami structures. These inflatables, fabricated at multiple scales (from fingernail-sized to body-sized), exhibit rapid, large contraction upon inflation up to 83.5% and provide tunable stretchabili…

X-Hair: 3D Printing Hair-like Structures with Multi-form, Multi-property and Multi-function

In this paper, we present X-Hair, a method that enables 3D-printed hair with various forms, properties, and functions. We developed a two-step suspend printing strategy to fabricate hair-like structures in different forms (e.g. fluff, bristle, barb) by adjusting parameters including Extrusion Length Ratio and Total Le…

SnapInflatables: Designing Inflatables with Snap-through Instability for Responsive Interaction

Snap-through instability, like the rapid closure of the Venus flytrap, is gaining attention in robotics and HCI. It offers rapid shape reconfiguration, self-sensing, actuation, and enhanced haptic feedback. However, conventional snap-through structures face limitations in fabrication efficiency, scale, and tunability.…
