General note his study examines the effect of major masked stereolithography (mSLA) process<br/>variables, namely, layer thickness, build orientation, and exposure time, on hardness of<br/>ultraviolet (UV) resin printed components. A Taguchi L9 orthogonal array design of<br/>experiments was used to perform nine experimental runs with Shore D hardness as the<br/>response variable measured per ASTM D2240. The parametric design allowed systematic<br/>testing of the parameteric effects with minimum number of trials. The results were<br/>interpreted using statistical methods, including analysis of variance (ANOVA), signal-tonoise (S/N) ratio analysis, regression modeling in order to determine the best processing<br/>conditions. Results show that exposure time is the most noticeable variable, with a<br/>contribution to the total variation in hardness of about 70 percent, build orientation and<br/>layer thickness added 13.5 per cent and 12.8 per cent respectively, and showed significant,<br/>but minor, effects on the response. The S/N ratios main effects plot indicated that the best<br/>parameter set to obtain maximum hardness is 0.100 mm layer thickness, 45deg build<br/>orientation, and 21 seconds exposure time. Finally, the exposure time is identified as the<br/>essential control parameter of the hardness, and orientation and thickness as the secondary<br/>refinements. The research provides a sound framework for process optimization within<br/>SLA.
