Based on the results of mathematical modeling and theoretical research works, it was established that the most influential factors of 3D printing, affecting the quality and time of end products formation, are extruder die temperature, layers height, speed of printing head movement during the formation of products, as well as simultaneous fabrication of several products within one cycle. In the work, the modes of the FDM 3D printing process were worked out and the regularities of the influence of the mentioned parameters on the structure and properties of resulted 3D polylactide products were established. The parameters of products formation were experimentally determined, which provide the production of 3D objects with predicted properties: maximum strength (98% of filament strength), high aesthetic quality (surface smoothness and resolution) and products with minimal investments of time during their production.
