Abstract
A method and system for providing cooling to a part formed using high-temperature additive manufacturing process. Infrared sensors or cameras are used to measure sidewall temperatures and, optionally, top layer temperature. Coolant nozzles provide cooling to the sidewalls of the finished layers and, optionally, to the top layer. The coolant intensity of the coolant nozzles is controlled in order to reduce temperature gradients between layers and/or to maintain temperatures in each layer below preferred maximum temperature.
