CURRENT ISSUES IN 3D PRINTING CONTROL METHODS FOR UNMANNED AERIAL VEHICLES PRODUCTS

Today, it is already quite clear that the adoption of additive technologies necessitates adjustments to the design principles of unmanned aerial vehicles (UAV), the development of printing technologies, the use of new construction strategies, and the creation of a stock of spare parts and components. Therefore, the assessment of the quality control of products printed on 3D printers is an important element of modern UAV, especially when selecting components. The UAVs repair system in field conditions must ensure complete coverage of all faulty samples, high reliability quality indicators of the repaired equipment, and the restoration of their operational capability within specified operational-tactical timelines. Losses in combat potential can typically be restored not only through repairs but also by acquiring new samples to replace those that have failed. However, the effectiveness of this approach to restoring the combat potential of the troops is not equivalent. Rapid and high-quality repair of UAVs in field conditions will be decisive in modern combat. Thus, quality control of printed products in field conditions will be the main criterion for determining the readiness of UAVs for operational use after repairs in the field. The article discusses the issues related to the methods of controlling 3D printing of UAV products. It is shown that reducing the likelihood of human error is very important for ensuring the quality of parts printed on a 3D printer. It has been established that digital control through 3D scanning allows for the creation of internal, repeatable, and precise verification workflows for all UAV parts in field conditions. The main task of 3D scanning, which will help optimize the quality of 3D printing, is to control geometry for comparison with a reference model. The use of 3D scanners enables the rapid tracking of defects in printed parts and provides a report on deviations from the declared geometry compared to the reference CAD model. Additive technologies (AT) provide the opportunity to produce UAV components of a specified shape and necessary sizes, even in field conditions, which significantly enhances the survivability of UAVs. The use of AT allows for a substantial reduction in the time required to restore UAV components, as well as a decrease in material costs. Another important advantage of AT is the relatively rapid manufacturing of UAV components with very high quality indicators.
