We choose the classic tetrakaidecahedron lattices, or Kelvin foam, as protection structures. Under compressive loading, the individual members of the lattice will first bend before eventually fracturing . It is expected that the lattices printed from the flexible elastomers will deform elastically up to high strains, enabling repeated large deformation without fracturing and exceptional impact absorption properties. We use our customized SLA printer to transform the 0.5% crosslinker resin (S0.5) to a 3D structure consisting of 2×2×2-unit cells and with nominal dimensions of 2×2×2cm. We change only the diameter of the truss members to achieve different relative densities of 19.5, 29.0, and 35.3%, which correspond to apparent compressive moduli of 5.2 kPa, 19.2 kPa, and 42.4 kPa, respectively (Figure ). These stiffnesses are dramatically lower than the bulk 0.5% crosslinker material (S0.5) that has a compressive modulus of 209.3 kPa (Figure ). Regardless of their relative density, all tetrakaidecahedron structures can be repeatedly compressed to 80% strain without fracturing (Figure , 12, and 13). The energy dissipation efficiency, defined as the ratio of the area enclosed by the loading-unloading hysteresis loop to the area under the loading curve, is 18.6, 21.3, and 20.0% for the 19.5, 29.0, and 35.3% relative density structures, respectively. Moreover, the compressive stress of the 3D structures is dramatically lower than that of the bulk counterpart. For instance, at 40% strain, the 3D structure with 29.0% relative density exhibits a stress of 6.0 kPa, nearly 25 times lower than 146.9 kPa for the bulk material (Figure ). For the 3D printed structures, there exists a wide window of compressive strain up to ~60%, within which the compressive stress is nearly plateaued. By contrast, for the bulk material, the stress starts to increase dramatically at a relatively low strain of ~30%. These results highlight the ability of 3D printed soft, elastomeric architectures to be deformed by a large extent to efficiently dissipate energy without being stiffened.
