Fused deposition modelling (FDM) which trending nowadays became a very promising additive manufacturing technique to process polymers. Even though, FDM had achieved a remarkable development, the mechanical strength of its products still in arguable condition. Various researches have been carried out to study the effect of printing parameters on the mechanical properties of FDM parts. This research covers the investigation of the effect of printing parameters on the tensile properties of the acrylonitrile butadiene styrene (ABS) printed parts using FDM technique to identify the optimum printing parameters. Implementation of this research comprises of printing of tensile test specimens using ABS thermoplastic according to ASTM D638-Type 1 standard with combinations of different raster angle and infill percentage. Tensile test is then performed to analyse the mechanical performance of the printed parts. The …
