Beschreibung
Zusammenfassung:	A method for use in additive manufacturing of a three-dimensional workpiece is described. The method includes depositing material onto a substrate to form a shape of the workpiece in accordance with an additive manufacturing process; determining a thermal characteristic of at least a portion of the workpiece during the additive manufacturing process; determining that the thermal characteristic of at least the portion exceeds a threshold associated with the portion; adjusting a cooling parameter of a cooling flow to be applied to the workpiece responsive to determining that the thermal characteristic of at least the portion exceeds the threshold associated with the portion; and applying the cooling flow with the adjusted cooling parameter to at least the portion of the workpiece.
