Atube with a rectangular cross section is to be fabricated by stereolithographny outside dimensions of the rectangle are 38 mm by 60 mm, and the corresponding inside dimensions are 30 mm by 52 mm (wall thickness = 4 mm except at cornerss) the height of the tube (z-direction) = 40 mm. layer thickness 0.20 mm, and laser spot diameter 0.25 mm. the beam velocity across the surface of the photopolymer 800 mm/s. compute an estimate for the cycle time to build the part, if 20 s are lost each layer for repositioning and recoating. ignore setup time
