Abstract
A method for managing the temperature of three-dimensional object during additive manufacturing includes depositing material on a partial fabrication of the three-dimensional object, determining thermal properties of the three-dimensional object after depositing the material, and controlling cooling of the object according to said thermal properties. In some examples, the determining of the thermal properties includes determining a temperature variation across the object and controlling position-dependent cooling of the object in a feedback arrangement. Resulting uniform temperature of the object under fabrication can improve dimensional accuracy and material properties of the object.
