Abstract

Additive technologies have made it possible to form a fundamentally new direction in the technology of unmanned aerial vehicles production, with the help of which it is possible to manufacture single and unique samples of products due to the layer-by-layer build-up of material by the method of layer-by-layer synthesis with the simultaneous obtaining of the given shape and dimensions of the next product based on a digital prototype. Modern capabilities of equipment and materials are rapidly evolving towards larger product sizes, higher accuracy and quality, high product printing speeds and low costs. When using traditional methods of production, the cost and complexity of unmanned aerial vehicles is quite high. The use of additive technologies allows you to significantly reduce the weight of the UAV body due to the reduction of material consumption. The article investigates the properties of various polymers used in additive manufacturing, determines their impact on the quality of unmanned aerial vehicles elements, and also develops a methodology for selecting materials for the manufacture of unmanned aerial vehicles elements. The conducted research revealed a whole layer of issues and problems related to the need to improve the 3D printing process, organization and management of the printing of complex elements of the air defense system, which would allow effective use of the latest additive 3D printing technologies in modern production in combat conditions. According to the results of the research, the properties of the main materials for 3D printing, which are used in the FDM technology of obtaining the product, have been established. It has been established that the use of additive technologies will entail the adjustment of unmanned aerial vehicles design principles, the development of printing technologies, the use of new construction strategies, and the emergence of new technologies related to 3D printing. The analysis of quality control mechanisms for the development of unmanned aerial vehicles elements shows that the technological scheme for the selection of composite material is an important element in the 3D printing of modern unmanned aerial vehicles and their components. It was determined that with the improvement of technological equipment and the development of methods of material selection for the manufacture of unmanned aerial vehicles elements, the direction of creating new unmanned aerial vehicles with the help of additive technologies will steadily expand.
