Investigations on Dimensional Analysis of Fused Filament Fabrication of Wax Filament by Taguchi Design 2019-28-0133

Experimental investigations were carried out on machinable wax filament using FDM 3D printing process. The printer used for conducting the experiments was Flash Forge guider 2. The filament material used for this study was machinable wax filament of 1.75 mm diameter. Experimental trials were carried out as per Taguchi L9 orthogonal array to determine optimum process parameter combination. The dimensional analysis of test samples were carried out in terms of change in volume of samples which is result of combine effect of deviations in all dimensions of test sample. Four factors each at three levels was used to obtain optimum printing parameters for better dimensional accuracy and proper printing. The four important printing parameters were taken as factor and set to analyze the significant factor affecting on printing. The complexity in printing of wax filament is taken in to consideration during the experimental study. The main effect plot for S/N ratio was plotted and ANOVA was carried out to determine the significant factor that was affecting dimensional accuracy of t printed test samples. The results shows that there is positive deviation in dimension along nozzle axis and dimensionally accurate and defect free printing is achieved with layer thickness of maximum layer resolution and vertical orientation. The defects are observed in inclined orientation samples due to support structure and delamination is detected. The Minitab software was used to analyze results obtained from experiment. The printing parameters, which are varied for experiment, are orientation, layer thickness, printing speed and travel speed.
