Calculate the time to complete a part using SLA printing in units of hours. The part is a vertical hollow cylinder with outer diameter = 100mm, inner diameter = 75mm, and height = 150mm. The top and bottom of the part are open (you can see all the way through the cylinder). The printer is set to scan at an average speed of 1000mm/s. The spot diameter of the printer’s laser is 0.1mm. The delay time between layers is 0.25s. Each layer is set to be 0.4mm in height.
