Abstract
The viscoelastic characteristics of materials based on ABS plastic and ABS/PC compounds depending on their composition have been studied by capillary viscometry; their effect on the characteristics of samples obtained by 3D printing by layer-by-layer surfacing has also been studied. A non-monotonic change in the effective viscosity depending on the composition of the compound is shown. It was found that the swelling coefficient in the range of shear rates implemented during printing for ABS/PC blends was higher than for the initial components, and the inlet pressure losses for the blends were minimal compared to the initial polymers. The mechanical characteristics in static bending increased with an increase in the content of PC in the ABS/PC blend.
