Abstract
An additive manufacturing machine includes a heated gas circulation system for regulating the temperature of additive powder throughout a powder bed and parts formed therein. The additive manufacturing machine includes a build platform defining a plurality of perforations and a heated gas supply that provides a flow of heated air into a distribution manifold and through the plurality of perforations and the powder bed to minimize temperature gradients within the powder bed which might otherwise result in distortion, thermal stresses, or cracking in the finished part.
