As a digital technology, AM can be used to produce complex parts that are difficult to make using traditional methods without the need for tooling. Hence, the aim of this study is to investigate the performance of Fused Deposition Modelling (FDM) in the manufacture of pump impellers. This involves performing simulation to test the performance of pump impeller under real-life working conditions at different operating speeds and pressures. The model of the impeller as casted in the FDM process was developed in the complete Abaqus modelling environment. The model part was created as single solid homogenous part with no nodal separations or assembly ties or constraints between the base of the impeller and its blades, in relation to its as-cast manufacturing state. The results obtained showed that extreme operating speeds of up to 1000 rad/s or pressures of 0.22 MPa are not suitable conditions under which the impeller will operate without compromising its efficiency and structural integrity. The study is useful in providing guidance on the application of FDM to produce functional parts. Through the study, the capability of AM as a suitable approach for enabling local sustainable production of spare parts is demonstrated.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/4IRAMFDMPump impellerSimulationPresentation
