4. Assume you are building with the ACES build style under the following conditions: layer thickness = 0.004", Dp=4.1 mil, Ec=11.4 mJ/cm² (SL-5510), machine = SLA-Viper Si2. (a) Determine the cure depths Cai and Ca2 needed. (b) Compute the laser scan speeds required for Cdi and Cd2. (c) Determine laser scan speeds required for Cdi and Cd2 when building along an edge of the vat, taking into account the laser beam angle.
