Analysis of the fatigue strength of models produced by the DMLS method for applications in the aerospace industry

Additive technologies are increasingly used in the aerospace industry due to the possibility of producing lightweight, high-strength structures for aviation applications. However, this requires the use of appropriate testing procedures for structural elements relevant to the construction of aircraft. In the case of the PBF - Powder Bed Fusion technology, the properties of the products are related to the quality of the powder used during the 3D printing process. The article presents the analysis of the fatigue strength of models produced by the DMLS method in relation to the quality of the powder bed.
