EXPERIMENTAL INVESTIGATION OF EFFECTIVE CHARACTERISTICS CHANGING FOR 3D PRINTING ELEMENTS

Abstract

The paper presents the results of experimental research on the change of effective characteristics in 3D printing elements in the presence of geometric heterogeneity and their reinforcement. The study was carried out in the case of compression tests along and across the orientation of the fibers. Test samples made on a 3D printer using PETG plastic were used for the research. It was established that the action of the compressive load in the direction perpendicular to the printing of the samples increases the elastic characteristics by 12%. Based on experimental studies, the effectiveness of the use of reinforcing elements and the optimization of the mechanical and strength characteristics of the parts were studied. The approach proposed in the work allows the optimize the operational characteristics of parts manufactured by 3D printing.
