Properties of PETG Plastic After 3D-printing Using FFF Technology. Part 2 DOI: 10.22184/2499-9407.2022.27.2.58.64
The influence of the 3D-printing mode on the complex of mechanical, optical and thermal properties of PETG (polyethylene terephthalate-glycol) thermoplastic transparent polymer material processed by additive FFF (Fused Filament Fabrication) technology is considered. The dependence between light transmission coefficient, sample thickness and orientation during 3D printing is shown.

Electroplastic Effect in Coarse and Ultrafine Grained Titanium DOI: 10.22184/2499-9407.2022.27.2.66.72
Electroplastic effect is studied in coarse- and ultrafine-grained titanium under joint effect of tensile strain and electric current of different types and modes. It is shown that reduction of grain size influences not only on increase of strength properties but also on decrease of electroplastic effect whose mechanism is closely associated with connected with the density of mobile dislocations.
