Experimental and numerical characterization of imperfect additively manufactured lattices based on triply periodic minimal surfaces

•Additively manufactured lattices based on triply periodic minimal surfaces exhibit excess material and surface roughness.•The presented modeling procedure enables the artificial reconstruction of the as-built morphology.•Using the reconstructed morphology drastically improves the accuracy of finite element simulations.•In the simulations, compressive stiffness and strength increase degressively with cell size.•The reconstruction procedure provides information about the mechanical degradation proportions of different defect types.
