Abstract

In some examples, an additive manufacturing process may be operated by a method that includes depositing a plurality of preliminary layers of build material over a build surface and applying thermal energy governed by closed-loop control to heat the preliminary layers. The method includes analyzing a temperature distribution across a layer of the preliminary layers to map the locations of any hot spots relative to the build surface. The method includes selecting a spray pattern to apply a cooling agent to the mapped locations.
