Effect of 3D-Printing on the Elastic Properties of Filament ABS Polymer Specimens

— The paper reports some results of experimental study on the effect of 3D-printing on the linear and nonlinear elastic properties of ABS polymer specimens manufactured in the form of thin filaments with 100% filling. The initial and 3D-printed ABD polymer specimens were studied by the static and Thurston–Bragger methods. Linear and nonlinear Young’s moduli and second-order nonlinear acoustic parameters were determined for several loading–unloading cycles of a specimen. It has been shown that the selected 3D-printing mode does not almost change the strength characteristics of ABS polymer, and its plastic characteristics even become slightly better. It has been revealed that mechanical loading has different effects on the nonlinear parameter of the initial and 3D-printed specimens. For the 3D-printed specimen, the nonlinear parameter is observed to decrease with increasing load.
