Abstract
An additive manufacturing system includes a platen, a dispenser apparatus positioned above the platen to dispense a layer of powder over the platen, and an energy source to selectively fuse the layer of powder. The dispenser apparatus includes a support structure, a dispenser secured to the support structure and including a reservoir to hold the powder and one or more openings configured to deliver powder from the reservoir in a linear region that extends along a first axis, a spreader extending along the first axis and secured to the support structure and positioned to spread powder already delivered on the platen by the dispenser, and a drive system to move the support structure along a second axis perpendicular to the first axis such that the dispenser and blade move together to sweep the linear region along the second axis to deposit and level the powder.
