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.…

Touch-n-Go: Designing and Fabricating Touch Fastening Structures by FDM 3D Printing

Touch fastening structures are widely used to quickly assemble and disassemble an object with multiple parts. However, such structures are under-explored in the context of additive manufacturing for personal fabrication. We proposed Touch-n-Go, a method for designing touch-fastening structures with customizable mechan…

ThermoFit: Thermoforning Smart Orthoses via Metamaterial Structures for Body-Fitting and Component-Adjusting

"Smart orthoses hold great potential for intelligent rehabilitation monitoring and training. However, most of these electronic assistive devices are typically too difficult for daily use and challenging to modify to accommodate variations in body shape and medical needs. For existing clinicians, the customization pipe…

All-in-One Print: Designing and 3D Printing Dynamic Objects Using Kinematic Mechanism Without Assembly

The field of Human-Computer-Interaction (HCI) has been consistently utilizing kinematic mechanisms to create tangible dynamic interfaces and objects. However, the design and fabrication of these mechanisms are challenging due to complex spatial structures, step-by-step assembly processes, and unstable joint connection…

4Doodle: 4D Printing Artifacts without 3D Printers

4D printing encodes transformability over time, which empowers users to create artifacts by on-demand deformation. The creative process of 4D printing shape-changing artifacts can be challenging because of its discontinuous fabrication steps, such as digital designing, specific path planning, automatic printing and ma…

X-Bridges: Designing Tunable Bridges to Enrich 3D Printed Objects' Deformation and Stiffness

Bridges are unique structures appeared in fused deposition modeling (FDM) that make rigid prints flexible but not fully explored. This paper presents X-Bridges, an end-to-end workflow that allows novice users to design tunable bridges that can enrich 3D printed objects' deformable and physical properties. Specifically…
