In this paper, the high-entropy alloy AlMnFeCrNiCu was fabricated using 3D printing technology from a mixture of pure metal powders. The microstructure and mechanical properties of the alloy were studied on thin wall samples. The results show that the alloy has a mixed structure of two phases: face-centered cubic and body-centered cubic. Tensile strength, yield strength, and elongation are 936 MPa, 563 MPa, and 32%, respectively. The alloy obtained by the 3D printing method demonstrates outstanding mechanical properties, which are both high durability but still ensure good ductility.
