The new challenges in the aerospace field lead to the need to develop new materials with complex shapes, without major intervention in their definition. Thus, laser 3D printing technologies have been developed for both composite and metallic materials. This paper presents a study of characterization and testing of a 3D printed metal material (Maraging steel 1.2709) in three different directions (x, y and z) to observe, from a mechanical point of view, the behavior depending on the printing direction and the structural changes that intervene following the tensile stress. Mechanical tests consisted of tensile testing in accordance with current international standards, and morphostructural analyzes consisted of investigation of the failure area using optical microscopy and scanning electron microscopy (SEM), respectively.
