This paper presents the results of the experimental research of 3D structures developed with an SLA additive technique using Durable Resin V2. The aim of this paper is to evaluate and compare the compression curves, deformation process and energy-absorption parameters of the topologies with different characteristics. The structures were subjected to a quasi-static axial compression test. Five different topologies of lattice structures were studied and compared. In the initial stage of the research, the geometric accuracy of the printed structures was analysed through measurement of the diameter of the beam elements at several selected locations. Compression curves and the stress history at the minimum cross-section of each topology were determined. Energy absorption parameters, including absorbed energy (AE) and specific absorbed energy (SAE), were calculated from the compression curves. Based on the analysis of the photographic material, the failure mode was analysed, and the efficiency of the topologies was compared.
本文介绍了使用耐用树脂V2通过SLA增材技术开发的3D结构的实验研究结果。本文的目的是评估和比较具有不同特性的拓扑结构的压缩曲线、变形过程和能量吸收参数。对这些结构进行了准静态轴向压缩试验。研究并比较了五种不同拓扑结构的晶格结构。在研究的初始阶段，通过测量几个选定位置的梁单元直径来分析打印结构的几何精度。确定了每种拓扑结构最小横截面处的压缩曲线和应力历史。根据压缩曲线计算了能量吸收参数，包括吸收能量（AE）和比吸收能量（SAE）。基于对摄影材料的分析，分析了失效模式，并比较了拓扑结构的效率。
