a Photograph of tensile specimens before and after foaming. b Tensile stress-strain curves of the as-printed PUE-4 and foamed PUE-4. c Real-time images showing the tensile deformation of PUE-4 foam. d Comparative analysis of tensile strength and elongation at break between foamed PUE-4 and hierarchically porous materials reported in the literature (see Table S2 for details and references). e Compressive stress-strain curves of solid block, (f) foamed block, (g) solid Kelvin lattice, and (h) foamed Kelvin lattice under cyclic compression. i Energy dissipation ratio, (j) residual strain, and (k) retention of max stress of solid block, foamed block, solid Kelvin lattice, and foamed Kelvin lattice.
