Abstract: To implement various design solutions that were proposed by the authors on the formation of a geokhod bladed shape by a helicoid, sound technological solutions for the manufacture and rapid prototyping of blades in a single production environment will be required. The additive manufacturing process allows you to create complex geometric shapes and structures that are difficult or impossible to achieve using traditional production methods. The advantages of using additive manufacturing for the manufacture of a helicoid-shaped bladed include the ability to quickly and accurately implement complex designs, an individual approach to design and production, as well as reducing the time and cost of manufacturing prototypes and small-scale batches. It is important to take into account the characteristics of the material and the technical characteristics of the final product to ensure its effective operation in the operating conditions of the geokhod. In this regard, additive manufacturing technologies in such conditions for the manufacture of blades of the helicoid shape of the executive body of the geokhod is an alternative option and does not require large costs for the manufacture of technological equipment and other technical means that are required in the manufacturing process according to the traditional method. In order to reduce the mass characteristics, topological optimization of the helicoid shapes of the blades was carried out while maintaining the best structural rigidity and meeting the strength conditions. Topological optimization was performed in specialized Solidworks software. As a result of the study, optimal helicoidal shapes of the blades of the executive body of the geokhod were obtained from the point of view of saving material while maintaining the conditions of rigidity and structural strength. Also, in the course of this work, the dependence of the strength coefficient of a straight helicoid body on the percentage of weight reduction was obtained. It is assumed that in the future, selective laser sintering technology will be used to manufacture these molds.
