Some Properties of PETG Plastic After FFF 3D-Printing. Part 1 DOI: 10.22184/2499-9407.2022.26.1.52.59
This article discusses the analysis of a set of properties of a thermoplastic transparent polymeric material PETG (polyethylene terephthalate-glycol) after its processing using the FFF additive technology (material extrusion, Fused Filament Fabrication). The effect of the 3D printing mode on the complex of properties of a polymer material is considered: mechanical, optical as well as thermal ones. The obtained results illustrate the relationship between%-light transmission, thickness and sample orientation during 3D printing.

Effect of Multigraphene Additives on Properties of Products Sintered from Stainless and Tool Steel Powders DOI: 10.22184/2499-9407.2022.26.1.82.90
The results of the study of the influence of multigraphene additives on properties of products sintered from stainless and tool steel powders by hot pressing show that additives of multigraphene increases hardness by 10% and decreases porosity by 16%. The presence of multigraphene activates the process of healing of large porosity due to the effect of critical wetting.
