EFFECT OF FDM PROCESS PARAMETERS ON PRINTING TIME, PART WEIGHT AND DAMPING FACTOR FOR ABS MATERIAL

Abstract

The current study focus upon the effect of fused deposition modeling parameters over printing time, part weight and damping factor. The study considers three FDM input factor such as infill density, layer height and print speed varied in two levels. Taguchi’s orthogonal array has been adopted for creating the experimental layout and output responses have been analyzed using appropriate signal to noise ratio method. The response table rankings and main effect plot indicates the significant parameter and optimal combination of input factors for controlling the output responses. Infill density is the most significant factor for both printing time and part weight of the sample prepared. Layer thickness is most influencing over damping factor of the sample. Printing speed is found to be the least significant factor over printing time and damping factor of the material. The change in layer thickness from 0.15mm to 0.20mm at 50% infill density has decreased printing time by 11.59%, but part weight and damping factor enhanced by 14.96% and 160% respectively. Similarly, at 100% infill density with 0.15mm layer thickness, printing time increased by 98.5% , part weight and damping factor increased by 84% and 59.63% respectively.
