Tests of mechanical properties of semicrystalline and amorphous polymeric materials produced by 3D printing

Abstract

The article presents the results of tests of physical properties of samples from semi-crystalline and amorphous polymeric materials produced using 3D printing. Samples were produced using 3D printing technology on the SIGNAL -ATMAT printer. The following polymeric materials were used to make the samples: TPU thermoplastic polyurethane elastomer, ABS acrylonitrile-butadiene-styrene copolymer, Laywood, PET ethylene terephthalate, PLA poly (lactic acid). The materials were tested for their mechanical properties. The hardness was determined by the Shore method and the ball-pressing method. The tensile strength also was determined. The research samples were subjected to visual analysis on a Keyence microscope to analyze the breakthrough site.
