OriStitch: A Machine Embroidery Workflow to Turn Existing Fabrics into Self-Folding 3D Textiles
🤖 AI Summary
This work addresses the challenge of transforming planar textiles into programmable 3D self-folding structures. We propose OriStitch, a computational weaving workflow that embeds thermoresponsive stitches—via machine embroidery—into conventional fabrics (e.g., denim, leather), enabling directional folding upon thermal actuation. We introduce the first textile-oriented, thermally driven self-folding hinge design, compatible with diverse materials including suede, cork, neoprene, and felt, ensuring stable and repeatable deformation. Our end-to-end pipeline integrates automatic 3D mesh unfolding, parametric hinge modeling, thermoresponsive stitch simulation, and co-design of fabrication and actuation. Experimental evaluation demonstrates successful transformation of 23 out of 28 target models—including hats, handbags, and custom-shaped vase covers—each incorporating 303–338 hinges—validating the robustness, material versatility, and scalability of the approach.

📝 Abstract
OriStitch is a computational fabrication workflow to turn existing flat fabrics into self-folding 3D structures. Users turn fabrics into self-folding sheets by machine embroidering functional threads in specific patterns on fabrics, and then apply heat to deform the structure into a target 3D structure. OriStitch is compatible with a range of existing materials (e.g., leather, woven fabric, and denim). We present the design of specific embroidered hinges that fully close under exposure to heat. We discuss the stitch pattern design, thread and fabric selection, and heating conditions. To allow users to create 3D textiles using our hinges, we create a tool to convert 3D meshes to 2D stitch patterns automatically, as well as an end-to-end fabrication and actuation workflow. To validate this workflow, we designed and fabricated a cap (303 hinges), a handbag (338 hinges), and a cover for an organically shaped vase (140 hinges). In technical evaluation, we found that our tool successfully converted 23/28 models (textures and volumetric objects) found in related papers. We also demonstrate the folding performance across different materials (suede leather, cork, Neoprene, and felt).
