Abstract
A comprehensive study of the rheological properties of ABS-plastic grades used for the manufacture of fi laments for 3D printing by the FDM method has been carried out. It is shown that under the printing temperature-speed conditions, the viscous properties of melts of different grades and activation energy of their viscous flow differ significantly. The temporal parameters of the thermal stability of melts at an elevated (250°C) temperature were determined by the rheological method. It is shown that, under printing conditions, the polymer does not undergo noticeable degradation, assessed by the change in its effective viscosity. Viscoelasticity, which determines the dimensional accuracy of products and the thickness of the deposited layer, was evaluated by the degree of swelling of the extrudate under different flow conditions. Criteria for the applicability of ABS-plastic grades for fi lament production are proposed.
