Abstract

A detailed study of the effects of layer thickness, hatch spacing, hatch overcure depth, and hatch fill cure depth on the quality of the StereoLithography (SL) product was carried out using acrylic based resin. Taguchi Method was used for analysing all experimental results. The ANOVA and the Signal-to-noise ratio (SIN) results were used to select the optimum parameters and the appropriate factor levels for further experiments. A new hatch styIe with an optimum layer thickness is proposed for the build process with minimum geometrical distortion.
