The object of research is the nozzle plugs of the “membrane” type. Considering the specific-strength properties of the product during its operation during operation, as well as the features of the FDM-process, the design was optimized, the regularities of the formation of its properties were established. An impregnation technology has been developed to seal the product. The equipment was designed, and pneumatic tests were carried out. The properties of materials were investigated considering their guaranteed shelf life for 12 years of operation under accelerated climatic tests. It is shown that the production of products by FDM-printing methods is promising and expedient, since the properties being formed are predictable, achievable, and stable.ennozzle plugadditive technologies3D printingstrength calculationspneumatic testsпробка соплааддитивные технологии3D-печатьпрочностные расчетыпневматические испытанияадитивні технології3D-друкрозрахунки на міцністьпневматичні випробуванняArticlePp. 282-293doi.org/10.20535/2521-1943.2021.5.3.246626621.70000-0002-5685-62250000-0001-8642-28260000-0002-8740-693X
