Additive manufacturing technology has developed rapidly and widely been used rapid prototyping technology based fused deposition modeling. The process of FDM product fabrication was being used the layer-by-layer technique. Acrylonitrile Butadiene Styrene (ABS) filament is one of material that often used in 3D printing technology and has high melting temperature. The objective of this study is to determine the optimum process parameters and the best combination of process parameters for the 3D printing process of PLA part using Taguchi method. The experimental design being used in this research was the orthogonal arrays of L9 (34) that has 9 experiments using 3 process parameters (nozzle temperature, extrusion width and infill density) and 3 level on each process parameter. The responses in this research were dimension accuracy (LO, WO, w and T) and tensile strength of 3D printing ABS product. Then data response result were analyzed using SNR and ANOVA. Based on SNR and ANOVA results that the most influencial of process parameters on the dimension accuracy response was dominated by nozzle temperature, and the tensile strength response was mostly influenced by infill density followed by nozzle temperature. Based on the experiment confirmation for tensile strength response using the combination of the optimum process parameter from Taguchi method, the results show that the tensile strength of the ABS parts significantly improve from 21,17 to 21.76 MPa at a confidence interval of 95%.
