Design of Experiments using a 2k factorial design for surfac

• Designed and printed helical gears using FDM while varying

• Designed and printed helical gears using FDM while varying 4 print factors in 2 levels. • Used independent observers with blocking done for part number to rate surface finish quality. • Used JMP Pro to model fit and compute RMSE, Rsq, p-value, and plotted least mean square.
