However, most components fabricated by 3D printing so far have been static structures with fixed shapes and monotonic functions. An arbitrary 3D object with complexities in shape and material can be built layer-by-layer from the bottom up. This tunability can significantly increase the use of bistable structures in various 3D-printed components.ģ-dimensional (3D) printing, also called additive manufacturing, is a new paradigm in customized manufacturing 1, 2, 3. We can readjust the bistability-energy diagram (barrier height, slope, displacement, symmetry) after printing and achieve tunable bistability. Moreover, we demonstrate tunable bistable components exploiting shape memory polymers. Therefore, these bistable structures can be useful for simplified motion control in actuators or for mechanical switches. Bistability produces a well-defined energy diagram, which is important for precise motion control and reconfigurable structures. To this end, we have introduced special joints to construct twisting and rotational structures without post-assembly. Particularly, we demonstrate 3D printing of twisting and rotational bistable structures. Here we introduce bistability to 3D printing to realize highly-controlled, reconfigurable structures. However, most components fabricated so far have been static structures with fixed shapes and functions. Three-dimensional (3D) printing is ideal for the fabrication of various customized 3D components with fine details and material-design complexities.
