Abstract
The work shows the possibility of manufacturing products for rocket and space technology using the additive FDM-printing technology. The object of research is the nozzle plugs of the "membrane" type. Taking into account 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 taking into account 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.

The introduction of 3D printing technology, which makes it possible to manufacture products of any shape and complexity in one technological transition, without additional processing, is seen as an alternative to expensive shaping tooling for the manufacture of complex-shaped products with subsequent machining
As an object of analysis, a nozzle plug installed in the nozzle of a rocket engine was selected, Fig. 1
