| Abstract |
| The aim of the work is to study the structural and optical properties of polymeric materials depending on the types of 3D printing patterns. Five cylindrical samples of the same size were printed on a 3D printer made of polyethylene terephthalate glycol (PETG) – plastic. The samples have the same dimensions: the diameter of the samples is 2 cm, the thickness is 0.5 cm. Samples are different in types of 3 D printing patterns. Research methods and results. The surface morphology of the samples was assessed using a JSM 6510 LV Scanning Electron Microscope. According to the results of microscopy, it was concluded that there are corresponding surface differences depending on the type of 3D printing pattern. Diffraction patterns of the starting material (filament) and the sample printed on a 3D printer were obtained on a DRON 4-07 diffractometer. Diffraction studies have shown that the phase composition and the original structure of the material are preserved as a result of printing. IR transmission spectra obtained on a Vertex Brucker IR-Fourier spectrometer in the range from 0 to 4000 cm-1. IR spectra showed the presence of 4 main vibration modes: 723 cm-1 (Interaction of polar ester groups and benzene rings), 1093 cm-1 (Methylene group and C-O ester vibrations), 1244 cm-1 (Terephthalate group (OOCC6H4-HCOO) ), 1713 cm-1 (C=O stretching of carboxyl group). The vibration modes of the samples coincide in terms of wave numbers and vibration intensities. The IR spectroscopy data correlate well with the literature data. |
