Comparative Study of Part Characteristics Built Using Additive Manufacturing (FDM)

It is found from the experimental results that the FDM process gives lowest surface roughness across the length is obtained for specimens built with orientation along YZ0, 100% infill and at 0.30 mm layer thickness. The sand paper polishing method yielded an immense improvement in the surface finish of the specimen. Increase in productivity i.e reduce in production time is obtained at 0.30 mm layer thickness, 20% infill at XY0 orientation.
