The conditions for the interaction of a jet of a binder fluid with polymeric materials are studied, and the properties of polymeric materials for the layer-by layer synthesis of powder materials are analyzed. Methods of forming parts in electronic instrumentation determine the configuration, size and quality indicators of parts. A promising method for manufacturing prototypes of parts is the method of layer-by-layer synthesis of powder materials on a 3D printer. With such a manufacturing technology, there are a number of problems. Firstly, the difference in the polymerization rate at different depths of the layer of polymeric materials leads to different degrees of curing of the powder material. Secondly, shrinkage chemical stresses arising during the synthesis of the part.
