Paper-crafted 3D origami structures composed of the Tachi-Miura polyhedron (TMP) cells have attracted much attentions due to their unique properties such as negative Poisson’s ratio. The TMP unit cell can be utilized for cellular solids to tailor structures and mechanical properties depending on its geometrical design parameters by leveraging additive manufacturing. Here, we report on the compression behavior of additively-manufactured polymeric and metallic cellular solids composed of the TMP cells. Effects of geometrical design parameters on compression behavior of the TMP unit cell were investigated. Especially, shock-absorbing properties in the force-displacement relationship of the TMP cells controlled by geometrical design parameters were focused on for an application as shock-absorbing materials. The multi-TMP cellular solids were also designed and additively manufactured to tailor structures and mechanical properties. This work demonstrates the potential for designing new type of architected cellular solids based on the multi-TMP cells to obtain lightweight shock-absorbing materials.
