Abstract
The fusion between the layers of a 3D printed part greatly influences the overall mechanical properties and can reduce its applications in certain domains. In order to obtain a better bonding between layers a study on the influence of printing temperature on the tensile strength of 3D printed parts is needed. The mechanical experiments were made on printed parts with polylactic acid material (PLA) on an open-source 3D printer with filament fabrication technology (FFF). The study is made on parts with the same layer height, infill ratio, dimensions, printed at the same speed. The obtained results show the influence of material printing temperature and the fast cooling on the mechanical properties of the 3D printed parts.
