Questions A prototype of a tube with a square cross section is to be fabricated = 100 using stereolithographic. The outside dimension of the square mm and the inside dimension = 90 mm (wall thickness = 5 mm except at corners). The height of the tube (z-direction)= 80 mm. Layer thickness = 0.10 mm. The diameter of the laser beam ("spot size") = 0.25 mm, and the beam is moved across the surface of the photopolymer at a velocity of 500 mm/s. Compute an estimate for the time required to build the part, if 10 s are lost each layer to lower the height of the platform that holds the part. Neglect the time for post curing.
