A brief description of the technology of selective laser melting (SLM) is given, the advantages and disadvantages of technology are noted. An analysis of literary sources dedicated to the study of the effects of hatching parameters of the SLM process of metal-powder compositions made of aluminum alloys to the physico-mechanical properties of finished products. A geometric model of the part is chosen as an object of study, its layered view. The subject of the study is mathematical models and trace methods, which make it possible to realize the partition of the partition section, taking into account the specified physical and mechanical requirements and design and technological restrictions. The author proposed a technique that allows you to simulate the physico-mechanical properties of products from aluminum alloys due to the selection of the parameters of the hatching of the SLM process. The mathematical task of the implementation of the partition hatching of the part with the specified parameters is represented as the task of tracing the trajectory of the laser beam inside the layer. Directions for further research in this area are determined.
