Problem 4. (Build Cycle Time in Stereolithography) The square cup-shaped part shown is fabricated using stereolithography. The base of the cup is 35 mm on each side and 4 mm thick. The walls are 3 mm thick, and the total height of the cup = 50 mm. The SL machine used for the job uses a spot diameter = 0.25 mm, and the beam is moved at a speed = 1000 mm/sec. Layer thickness = 0.10 mm. Repositioning and recoating time for each layer = 20 sec. Compute an estimate of the cycle time to build the part if the setup time = 15 min. Figure for Problem 4. 50
