summary

A low-cost actuator prints a single-layer conductive PLA trace onto copy paper with an FDM MakerBot, heat-sets in an oven (70 °C, ~10 s) to create a bilayer shape-memory hinge, and flattens under Joule heating when powered; it reliably cycles but overheats and chars if driven too hard. Experiments show narrower zig-zag elements yield larger bending angles, and around 4–9 V on small samples gives maximum bend with repeatability. A linear resistance-to-angle mapping enables self bending-angle detection. Demos include a gripper, crawling robot, pop-up book, mimosa leaf, and a variable lampshade.
