Abstract
A method of fabricating a part includes: a) supplying powder particles; b) melting a first quantity of power with a beam and forming, on a support, a first pool including the melted powder and a portion of the support; c) forming a second pool by melting a second quantity of powder on the support; d) repeating c) to form a first layer; e) heating an [n]quantity of the powder, and forming an [n]pool above the first layer; f) heating an [n+1]quantity of the powder, and forming an [n+1]pool downstream from the [n]pool above the first layer; g) repeating f) to form a second layer above the first layer; and h) repeating e) to g) until the part is constructed. The powder particles reaching each pool are at a temperature well below the pool temperature.
