#4825 Print-in-Place Flat-Pack or Kit Cards #4825 Discuss 3D printed origami 3D printed origami bridges classical computational geometry with additive manufacturing, transforming flat or compact planar layouts into reconfigurable, deployable three-dimensional structures. By replacing traditional zero-thickness paper with real-world materials that possess finite thickness and mechanical stiffness, additive fabrication enables metamaterials, compliant mechanisms, and self-folding assemblies. Core Kinematic & Geometric Challenges Classical origami assumes zero-thickness sheets that deform solely along infinite, frictionless fold lines (creases) while leaving the facets completely rigid. Physical 3D prints introduce thickness ( t > 0 ), demanding specialized geometric adaptations: Thick-Panel Origami: If facets have finite thickness, simple folding leads to self-intersection and mechanical binding. Engineers compensate using: Offset Hinges & Axis-Shift: Shifting hing...
