Abstract Fused filament fabrication, well known as fused deposition modeling
(FDM), is a rapid prototyping method that employs thermoplastic filaments in a semimolten state. These filaments are pushed out from the nozzle’s orifice for fabricating
the required components. Henceforth, it is essential to comprehend the governing
factors that influence the quality of FDM products. In this context, the FDM process
parameters have been tuned, and an attempt is made to analyze the enhancement in
dimensional accuracy of components made by the fused filament fabrication technique. Raster angle, orientation, layer thickness, and the number of contours are
considered as process variables. The components are made up of ABSM30 (acrylonitrile butadiene styrene), and their dimensional accuracy has been impacted by
aforesaid variables and interactions between them. Response surface methodology
(RSM) is employed in consideration of enhancing the dimensional accuracy. The
results reveal that the aforesaid variables and interaction between them govern the
dimensions of the build parts in a diverse direction. This dimensional inaccuracy
is caused because of the shrinkage of semi-molten thermoplastic, which leaves the
nozzle. Here, the dimensional inaccuracy has been analyzed in terms of volumetric
deviation.
