Abstract: The deformation behavior of 3D 03X17H14M2 steel samples with various lattice structures created by selective laser melting has been studied under compression conditions using the digital image correlation method. Spatially temporal patterns of localization of transverse $(\varepsilon_{xx})$ and longitudinal $(\varepsilon_{yy})$ deformations of topological structure actual types have been studied. It has been found that it is possible to achieve a relative density of 20% for 3D printed products with lattice G-structures and cell sizes of 1.5 and 3 mm. However, all lattice 3D samples lose their plasticity, the Young’s modulus decreases by more than an order of magnitude, and the Poisson’s ratio increases by 1.3–2 times compared to the corresponding parameters for solid 3D samples.
Keywords: digital image correlation method, selective laser melting, topological optimization, lattice structures, deformation localization.
