In additive manufacturing, Fused Deposition Modelling (FDM) is the most common method among the different types which involves melting, extrusion and deposition of thermoplastic filament. It is the most extensively used additive manufacturing method for the reason of its capability to create components having complex shape. On the other hand, end-consumer functional component with fused deposition modelling confirmed to be a demanding assignment due to the influence of quality on wide variety of processing parameters of the build parts and their functionality. Further, the final part’s building time, mechanical properties requires a more intrinsic understanding to detail on the impact of the FDM processing parameters. This paper presents an experimental investigation on Acrylonitrile butadiene styrene (ABS) thermoplastic filament to assess the effects of process parameters such as infill density, infill pattern, layer thickness on the tensile strength. A set of test specimen specimens were printed using varying processing parameters for the experimentation of the tensile strength of each fabricated sample. From the findings of the experiments, suitable processing parameters for an assuring tensile strength were analyzed and studied to develop better end-user functional parts.
