Abstract: Techniques are described for consistently moving powder from a hopper into a trough for subsequent delivery into a build area of an additive fabrication system. A powder conveyer may be arranged at least partially within the hopper and configured to be actuated to transfer powder to the trough. The powder conveyer may be formed as a screw conveyor, for example. Such techniques do not require complex closed-loop control systems and may be effective irrespective of the flowability of the powder. In at least some cases, there may be no production of excess powder because the amount of powder that is metered into the trough may be precisely controlled to be the amount needed for recoating.

Abstract: Techniques are described for consistently moving powder from a hopper into a trough for subsequent delivery into a build area of an additive fabrication system. A powder delivery apparatus may comprise a hopper, a trough, and a doser. The doser may be configured to rotate about an axis and may include a recess that, when the doser is rotated about the axis, travels into and out of the hopper and into and out of the trough. As a result, when powder is present in the hopper, the recess may carry powder from the hopper to the trough when the doser rotates. The trough and doser may be configured so that when the trough contains the desired amount of powder for recoating, the doser does not transfer additional material from the hopper into the trough. As a result, the amount of powder in the trough may be self-regulating.
