3D Printing is an elementary tool for the free fabrication of objects that can be used in factory, commercial, academic and domestic scales. The technology has a low cost and high efficiency in the production of parts, which justifies its wide application. In order to manufacture a propeller for use in hydraulic benches, the object is modeled with a Revit tool and manufactured with a 3D printer. ABS is the material chosen for prototyping because it is the lowest cost and because it provides good mechanical resistance, although it requires attention regarding workability. In order to explore the best performance of the ABS material, a tensile test is carried out on Test Specimens (CP) manufactured with different filament deposition modes and compared to the values indicated by the manufacturer. Despite the mechanical resistance approaching ¼ of the indicated value, the behavior of the propeller in the reduced-scale hydraulic channel and the aesthetics of the object were satisfactory. However, the difficulty in obtaining the expected result is highlighted, due to the lack of maintenance on the printer and the complexity of modeling the part, since the part requires in-depth techniques of the modeling tool.
