  • RESIN LEVEL DETECTION IN ADDITIVE MANUFACTURING
    Publication number: 20240092025
    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 there between, 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.
