This work aims at evaluating the relative significance of the input parameters on the product
quality produced by Z510 3DP rapid fabricator. Taguchi’s L18 orthogonal array was employed to
investigate the possible process parameters including binder setting saturation value (shell &
core), layer thickness, and build orientation. Using a surface profilometer and CMM, a series of
measurements in evaluating the 3DP products surface finish and dimensional accuracy has been
carried out. Nonlinear regression model was developed and a statistical analysis was done to
determine the significant factors affecting the product quality of the fabricated products. Optimal
process parameter settings were proposed using Particle Swarm Optimization technique. The
results were validated by conducting the confirmatory experiments.Mechanical Engineerin
