The essence of the study is to investigate the change in dynamic-mechanical properties of polylactide acid (PLA) material, after its surface plasma-chemical modification using DCSBD plasma discharge, as a tool to achieve better adhesion when depositing individual layers of PLA filament during its 3D printing. Dynamic-mechanical analysis (DMA) is a suitable tool for determining the glass transition temperature (Tg) of a polymeric material. By measuring the Tg, it is possible to find out how difficult it is to print the material, because the closer the Tg temperature approaches to the room temperature, the easier the material will be printed. After the layer of material is printed onto the bed and cooled to room temperature, the material begins to shrink and curl due to the coefficient of thermal expansion, which adversely affects the adhesion between the layers of material and the deposited layers tend to separate.
