Abstract
A three-dimensional (3D) metal object manufacturing apparatus is operated to compensate for surface deviations of overhanging features differently than for non-overhanging features. The compensation technique used for the overhanging features depends on whether an edge of the overhanging feature being formed in a next layer has curved or sharp corners.
