Problem 3 (30 points): Consider a desired layer thickness and hatch spacing in the range of the SLA-250 (see Table below). Assume a beam half-width is 5 mils and a resin with known Dp Using Matlab or Excel, plot (a) Percent of Emax as a function of the distance Y [mm] as shown in the figure below. b) Cure Depth [mm] as a function of the distance Y mm] as shown in the figure below. (c) For the SLA-250, determine the minimum and maximum values of Cdo and Cdi.
