Abstract
In some embodiments, a method of determining the fill level of a resin pool in a bottom-up additive manufacturing apparatus includes the steps of: (a) providing an additive manufacturing apparatus including a build platform and a light transmissive window (), the build platform () and the window () defining a build region therebetween, with the window () carrying a resin pool, the pool having a resin top surface portion; (b) advancing the build platform () and the window () towards one another until the build platform () contacts the resin top surface portion; (c) detecting the impact of the build platform () with the resin top surface portion; and (d) determining the fill level of the resin pool from the detected impact.
