摘要：

The results of the study of the mechanical properties of cellular structures with various geometries made of polyamide-12, which are repeating in three directions structural elements having a geometric threefold periodic surfaces of minimal energy, are presented. Samples in the form of a cube (size 30 x 30 x 30 mm) were obtained by the method of layer-by-layer sintering of the powder material on a 3D printer of the SLS type (selective laser sintering). When comparing the experimental deformation curves, the types of samples with the best mechanical characteristics were established. (C) 2019 Elsevier Ltd. All rights reserved.
