The main advantages of this type of production are analyzed, the main one of which is the ability to manufacture parts with optimal topology. A promising direction for improving the operational characteristics of the structures being developed is the creation of an internal porous structure, which not only reduces the weight of the parts, but also makes it possible to influence its physical and mechanical characteristics. Some of the technologies most widely used in printing plastic and metal products are described. Methods of forming a layer of parts in additive manufacturing and the areas of application of each of these methods are considered. An example of successful practical use of a product with an internal porous structure is given. Keywords additive technologies, topological optimization, porous structure Funding: The work was supported by Ministry of Science and Higher Education of the Russian Federation (grant of the President of the Russian Federation for state support of young Russian scientists - candidates of sciences MK-1088.2021.4)
