applying energy to a curable material to form a cured material layer on a build platform or on an object on the build platform, wherein the object is a portion of a dental appliance;
conveying remaining curable material away from the build platform;
detecting, via one or more sensors, that the remaining curable material includes a portion of the cured material layer that has separated from the build platform or from the object; and
determining an adjustment to the energy to improve adhesion of cured material to the build platform or to the object.
