Example with two intersecting rotational degrees of freedom (DOFs). a Two desired intersecting rotational DOFs and, b their freedom and, c constraint spaces. Since the plane of the constraint space doesn’t fill all space, two intermediate freedom spaces must be used. d The constraint space of the first intermediate freedom space is used to synthesize the unit cells of, e the first layer. f The constraint space of the second intermediate freedom space is used to synthesize the unit cells of, g the second layer. h This process is repeated for alternating layers until the final directionally compliant metamaterial (DCM) is synthesized that, i, j achieves the desired DOFs. k The DCM can be additively fabricated and shaped as desired (scale bar in k, 10 cm, and colors in i and j are defined in Fig. 3b)
