Abstract: The recent most admired additive manufacturing (AM) technique is the fused deposition method (FDM) because of its low cost and ease of operation. The FDM printed parts often suffered with lack of global or average strength, because of more strength in printed direction and leads to anisotropic mechanical properties. The most effective methods to obtain high tensile strength are the optimization of process parameters of FDM process to manufacture high strength Acrylonitrile Butadiene Styrene (ABS) samples. The present research paper objective is to analyze the process parameters effect on tensile strength of FDM printed specimen with ABS. The specimen is prepared as per the D638 ASTM standards. The specimens are printed in accordance with L9 matrix a Taguchi method. The chosen FDM process parameters are fill density with 40, 60 and 80(%), print speed with values of 60, 80 and 100(mm/min), and layer thickness 100, 200 and 300(microns). From the tensile strength investigation of ABS samples, the maximum tensile strength of 24.866 MPa is obtained with specimen build with the parameters, infill-80%, speed- 100mm/min and layer thickness 0.2mm. This proposed research work is useful to decide the effective FDM process factors and their working ranges to manufacture the ABS components or parts.
