A prototype of a part is to be fabricated using stereolithography. The part is shaped like a right
\r\ntriangle whose base = 36 mm, height = 48 mm, and thickness = 25 mm. In application, the part
\r\nwill stand on its base, which is 36 mm by 25 mm. In the stereolithography process, the layer
\r\nthickness = 0.20 mm. The diameter of the laser beam (“spot size”) = 0.15 mm, and the beam is
\r\nmoved across the surface of the photopolymer at a velocity of 400 mm/s. Compute the minimum
\r\npossible time required to build the part, if 8 sec are lost each layer to lower the height of the
\r\nplatform that holds the part. Neglect the time for postcuring.
