The research paper discusses the analysis of mechanical properties such as tensile strength, yield strength, Young's modulus, and elongation, as well as microstructural and hardness tests of three materials commonly used in additive manufacturing. The selected materials were 316L steel, AlSi10Mg aluminum alloy, and Ti6Al4V titanium alloy. The mechanical properties were evaluated using strain gauge measurements and digital image correlation, allowing for the determination of local material properties. The conducted research revealed that sample fractures were caused by defects resulting from the manufacturing process, often along the boundaries of sequentially deposited layers. However, tensile tests demonstrated that the tensile strength of additive manufactured components is comparable to or higher than those produced using traditional manufacturing techniques. The research results indicate the potential for utilizing additive manufacturing technology in the production of structural components under static loading conditions.
