Abstract
A method, system and apparatus for variably controlling the temperature in a selective deposition modeling environment. The temperature of the formed portion of the three-dimensional object is detected. A gas is forced onto a surface of the formed portion of the three-dimensional object. The forced gas has a characteristic, such as temperature and quantity, that is variably controlled based on the detected temperature of the formed portion of the three-dimensional object.
