Metamaterial Mechanisms
summary
Printed one-piece mechanisms transform interior cell geometry into movement: a door latch in one piece that converts handle rotation to linear latch travel, and a single-block Jansen walker that actually walks. A voxel editor (WebGL/three.js) with FEA via Caramba previews deformation; export uses OpenJ as cut to STL. Prototypes print in NinjaFlex, semi-flex, PLA and nylon; hinges use a 2:1 thickness ratio (stiffness ≈8:1). Durability test runs 5,000 cycles with no fractures; limitation: no continuous axles.
