Stereolithography is to be used to build a part as shown in the figure. Dimensions are; height= 23mm, outside diameter = 75 mm, inside diameter = 65 mm, handle diameter = 6 mm and handle distance from the cup = 70 mm (center to center). The handlebar has a cross-section of 5 x 6 mm?!The thickness at the base of the cup is 6 mm. The laser beam diameter is 0.25 mm with a speed of321 mm/s. Layer thickness = 0.20 mm. Estimate the time required to build the part if 10 s are lost from layer to layer preparation.
