Additive Manufacturing is increasingly taking space in the world industry and establishing itself as a good alternative to subtractive technologies. One of the areas of additive manufacturing that has shown to be very promising is Wire + Arc Additive Manufacturing (WAAM), which stands out due to its high deposition rate and the possibility of creating complex geometries with a great Buy-To-fly ratio, when compared, for example, to the machining process. In MADA, the deposition process by GMAW (Gas Metal Arc Welding) is highlighted, where the electric arc is used as a heat source. This work sought to analyze the geometric behavior of cylindrical parts manufactured by MADA, through experiments varying three main characteristics: Interpass temperature range, number of layers and diameter of the tube section. After manufacturing the experiments, a 3D scanner was used to generate a CAD model of the welded parts (in order to obtain the real dimensions of them) and an inspection of the heights was carried out through a comparison surface between the generated mesh. by the scanner and a “standard” 3D model. After the statistical analyses, only a trivial model was found, which, for the design used in this work, shows that the Number of Layers is the parameter with the greatest influence on the height of the experiments.
