However, they usually consist of intricate geometries which make the fabrication of them a significant challenge. The present paper is focused on introducing an interlocking assembly method to fabricate 3D PACSs. There are distinct advantages of the proposed method compared with the additive manufacturing methods used before. The dependences of mechanical properties of the structures on the re—entrant angle were investigated through a combination of experiments and numerical simulations. Results show that the compression modulus of the structures will monotonic decreasing with the increase of re—entrant angle, but there exists an extreme value for Poisson’s ratio with the re—entrant angle which is difference with former studies. The effects of the strut thickness and the ratio of the vertical strut length to oblique strut length on the mechanical properties of the structure were also investigated.
