In the present research work effort has been made to study the use of Acrylonitrile-Butadine-Styrene (ABS) replicas in investment casting applications.The research start with selection of the component for industrial application with an idea of improvement in accuracy and hardness of the component. The input parameters are production time in Fused Deposition Modeling (FDM), number of layers, layer combination and different materials in investment casting.The study highlights the percentage contribution of different input parameters on micro hardness and dimensional accuracy.
