Abstract
In one example, a temperature control system for a spreader roller in an additive manufacturing machine includes: a first duct to carry air to an air passage through the roller; a second duct to carry air away from the air passage through the roller; a fan to move air through the ducts; a temperature sensor to sense a temperature of the roller; and a controller to control a flow of air through the ducts based on a temperature sensed by the sensor.
