Fused deposition modelling (FDM) is the most diffused rapid prototyping (RP) technique but it suffers from poor surface quality and dimensional accuracy of fabricated components due to staircase effect. Researchers have successfully improved the surface finish of FDM based acrylonitrile butadiene styrene (ABS) replicas by treating them with vapors of chemicals like acetone. However, the reflow of the material caused by such vapors inherently affect the other properties like dimensional accuracy, surface hardness and tensile strength. In this book chapter, authors highlighted the effect of selected FDM and vapor smoothing (VS) process parameters on the shore hardness of ABS replicas as a case study. Taguchi’s L18 orthogonal array has been employed for investigation and optimization of input process parameters. Further, the scanning electron microscopic characterization of the components had been carried out for the justification of the results.
