The technology of additive printing is one of the fastest growing in the field of machinery, aircraft, shipbuilding, pharmaceuticals and others. This is achieved by the simplicity of the process of manufacturing finished products in comparison with traditional methods, speeding up the process of manufacturing prototype parts, etc. A large number of industry companies, scientists and enthusiasts made a great contribution to the study of additive technologies, promising directions of development and their further implementation in real enterprises.An analysis of previous studies showed that in similar studies, an analysis of the factors affecting the difference in strength of finished products in different directions was not carried out, and no methods of solving this problem were proposed. The ASTM D-638 standard was used for testing the specimens for stretching. Physic-mechanical properties, which are determined during the tensile test, are used to control the technology of their production and the quality of raw materials, to select raw materials in the design, in assessing the strength, rigidity and reliability of structural elements.The study showed a significant anisotropy of the properties between stretching along the fibers and washing with the direction. It is established that the values of the tensile loads in the longitudinal direction are 5-6 times greater than in the transverse load.
