Optimisation of Production Parameters of ASA Based Materials in Additive Manufacturing Process by Taguchi L16 Method

In this study, optimization of manufacturing parameters in FDM method with acrylonitrile styrene acrylate (ASA) polymer was carried out in accordance with Taguchi L16 design. For this purpose, four different layer thicknesses (0.12, 0.16, 0.20, 0.24), four different print speeds (80, 90, 100, 110 mm/s), four different nozzle temperatures (250, 255, 260, 265°C), four different table temperatures (60, 65, 70, 75°C) were used. The effects of manufacturing parameters on mechanical and physical properties were investigated. As a result of the analysis of the tensile strength of the samples, it was determined that the most effective parameter was layer thickness with a contribution rate of 38.41%, followed by table temperature with a contribution rate of 33.48%, print speed with a contribution rate of 17.89% and nozzle temperature with a contribution rate of 3.32%. In the impact strength, it was determined by ANOVA analysis that the most effective production parameter was layer thickness and the reliability rate of the analysis was 94.92%. In addition, it was determined that the most effective parameter in the hardness measured on the surface of the samples was layer thickness and this manufacturing parameter was followed by nozzle temperature, table temperature and print temperature, respectively. In the studies carried out to determine the dimensional accuracy value, which is one of the important criteria in determining the physical properties of the produced samples, it was determined that the most effective parameter in this property was layer thickness and the reliability rate of the analysis was 99.04%
