A cone-shaped part is to be fabricated using stereolithography. The radius of the cone at its base=35mm and its height =40mm. The layer thickness =0.20mm. The diameter of the laser beam=0.22mm, 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 10s are lost each layer to lower the height of the platform that holds the part. Neglect post-curing time.
