Touch-n-Curl: Designing and Constructing Skeletal Form through 3D Printing Flattened Zipper Assembly
summary
Touch-n-Curl converts a 3D skeleton into a pack of 3D-printed flattened zipper ribbons that unroll from conical, developable patches; a computational pipeline uses arc-length parametrization and a tree rectification step to minimize branch intersections and handle closed meshes. The parametric tool outputs printable 2D assemblies, parts print without extra supports, manual assembly takes minutes, and final pieces span millimeter to meter scales; evaluation reports faster fabrication, tunable rigidity, and good shape-matching and mechanical strength in demos (vase, spool holder, integrated electronics).
