The paper investigates the physical and mechanical properties of structures with the geometry of triply periodic minimal surfaces (TPMS). Test samples were made from polyamide using SLS (selective laser sintering) 3D printing technology, from polylactide using FDM (Fused deposition modeling) 3D printing technology, and from a photopolymer based on acrylates using LCD (liquid crystal display) technology; samples were made in the form of a cube with edge size 30 mm. The strength and energy-absorbing properties of TPMS-based cellular samples have been determined. To analyze the features of the geometry of the samples, the skeletal graph method was used. It is shown that this approach makes it possible to predict the physical and mechanical characteristics of products with TPMS geometry.
本文研究了具有三重周期极小曲面（TPMS）几何形状的结构的物理和力学性能。测试样品分别采用SLS（选择性激光烧结）3D打印技术由聚酰胺制成，采用FDM（熔融沉积建模）3D打印技术由聚乳酸制成，以及采用LCD（液晶显示器）技术由基于丙烯酸酯的光聚合物制成；样品制成边长为30mm的立方体形式。已测定了基于TPMS的多孔样品的强度和能量吸收性能。为了分析样品几何形状的特征，使用了骨架图方法。结果表明，这种方法能够预测具有TPMS几何形状的产品的物理和力学特性。
