Fused deposition modelling (FDM) is the most economical type of additive manufacturing (AM) technique. But, the poor surface texture and dimensional inaccuracy of FDM fabricated parts due to its fundamental working principle (layered manufacturing) limits the application domain of this technology. Researchers have successfully enhanced the surface finish of FDM based acrylonitrile butadiene styrene (ABS) replicas by treating them with hot or cold 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, researchers highlighted the dimensional accuracy of ABS replicas by integrating the FDM and vapor smoothing (VS) process. Taguchi L18 orthogonal array has been employed for optimizing the process parameters of combined process. The study highlighted that exposing ABS replicas to hot vapors of acetone resulted in dramatic improvement of surface finish with negligible variations in part dimensions.
