Abstract
An apparatus and a method using the apparatus provides heated air in an additive manufacturing process for building a three-dimensional part. The method comprises providing a stream of flowable part material at an initial build level, the initial build level being positioned in and defining a horizontal plane wherein the stream of flowable material is being initially disposed on previously deposited part material. Heated air is provided at a selected temperature corresponding to the temperature of the stream of flowable part material such that the stream of flowable part material deposits on previously deposited part material in an adhering fashion thereby forming the three-dimensional part wherein the heated air is provided in the horizontal plane of the initial build level.
