Influence of 3D-printing parameters on mechanical properties of polyethylene terephthalate glycol (PET-G) products

Abstract

The article considers the influence of such parameters as infill density, infill line directions and line width on the mechanical properties of samples made of polyethylene terephthalate glycol by FDM-printing. Mathematical expressions were obtained on the basis of the conducted research. These mathematical expressions allow to calculate the expected mechanical properties of the studied PET-G brand under uniaxial tensile, static and impact bending. The influence of variable FDM-printing parameters on the formed level of product properties is investigated, which will allow the selection of their values depending on the required tasks.
