Abstract3D re-entrant mechanical metamaterials were designed and fabricated with P mu LSE (Projection Micro Litho Stereo Exposure) 3D printing technique, synchrotron X-Ray tomography 3D imaging and in situ mechanical experi-ments were performed for characterizing additive manufacturing (AM) process induced internal defects, corre-sponding relations between defects and mechanical behaviors of harvested 3D re-entrant lattice samples were explored through experiments and simulations comparisons. Firstly, in situ micro compression mechanical test device was designed and constructed for in situ synchrotron X-Ray 3D tomography mechanical experiments; Af-terwards, interrupted in situ compression tests were performed for investigating the effects of manufacturing process induced defects on the deformation behaviors of 3D re-entrant lattice metamaterials, and finite element (FE) modeling was performed and compared with experimental results for understanding the mechanical behav-iors of as-fabricated 3D re-entrant lattice metamaterials.
