Abstract

An additive manufacturing system includes a platen having a top surface, a support structure, a powder dispenser coupled to the support structure and positioned above the platen and configured to deliver a powder in a linear region that extends along a first axis, a gas dispenser coupled to the support structure in a fixed position relative to the powder dispenser and having an outlet to deliver a gas across the outermost layer of feed material, an energy source configured to selectively fused the layer of powder, and an actuator coupled to the support to move the support with the powder dispenser and the gas dispenser together along a second axis perpendicular to the first axis and parallel to the top surface such that the linear region and the outlet sweep along the second axis to deposit the powder in a swath over the platen and deliver the gas.
