| dc.description.abstract | This report was based on the project at Aalen University in the scope of the curricular subject of the thesis, inserted in the study program of the master’s degree in Mechanical Engineering – Industrial Production. The project had a duration of six months. The project goal was to study the manufacturing process of metal parts using Fused Filament Fabrication (FFF). The FFF is a technique in which a fused filament is deposited controlled over or adjoining previous deposited filaments, leading to the construction of a structural part. To realize the evaluation of mechanical properties of FFF three dimensional (3D) printed parts it was performed in four main tasks: First, specimens were printed at 0º with three different infill patterns (gyroid, tri-hexagon, and quarter cubic) and two different infill densities (25% and 40%). The printing of these specimens was intended to perform density tests, tensile tests, and roughness tests. Secondly, small cubes with the same infill density (100%) were printed but with different infill patterns (gyroid, tri-hexagon, and quarter cubic) so that it was possible to compare the roughness on the different faces of the cube. These infill patterns and infill densities were chosen, to complement studies previously done by other colleagues. Third, 0°, 45°, and 90° specimens were printed with support structures to perform the charpy v test. However, performing these tests was impossible because the debinding and sintering company could not deliver the parts in time. At last, a cost analysis of the FFF process and the Selective Laser Melting (SLM) process in the production of a compressor turbine was made. With the tests performed throughout this study, it was possible to conclude that the debinding and sintering process influences the weight of the specimens and the infill density and pattern have an influence on the mechanical behaviour of the specimens. | pt_PT |
