The main methods of mechanical testing of composite materials include: determination of the strength of the material in tension, bending, torsion, compression, impact loads, etc. This article presents the methodology and results of tests for the bending strength of structural elements made of ABS plastic manufactured using 3D printing. The shape of the cross-section of the test specimens-beams and the percentage of filling their internal cavity with the specified polymer material were selected as design factors that are predicted to have an impact on the output parameter. The most optimal configuration was established and the dependence of the strength on the change in the specified variable factors was determined.
