The purpose of this study is to dictate an optimum process parameter during the fabrication of additively manufactured acrylonitrile butadiene styrene (ABS) based injection mold using fused deposition modelling methodology based additive manufacturing process and to assess the quality of the infection mold by analyzing the surface roughness of the injection mold, and the time taken in the manufacturing of the mold. The ABS PRO+ filament is used in manufacturing ABS-based injection mold which is manufactured by the WOL 3D. The printer used for manufacturing of ABS-based injection mold is manufactured by Creality Ender-3 3D printing machine working on the Fused Deposition Modelling or FDM principle. FDM is a filament-based process and uses polymer-based filament for printing. The filament used in developing the mold has a nozzle temperature of about 250°C and a bed temperature of about 90°C. The mold was manufactured by changing different process parameters such as speed of printing and layer height of printing and all the other parameters of the experiment were kept constant throughout the experiment. Three parameters of both layer height and printing speed are taken for this study. A total of nine molds were manufactured at different combinations of layer height and printing speed. The 3D printed mold was then analyzed for the processing effects on the surface roughness and time taken in 3D printing of the injection mold. The study concluded the optimum value of printing speed and layer height for better surface finish and less time consumption for 3D printing the injection mold.
