Abstract:
An additive manufacturing apparatus includes a dispensing system positionable over a platen to deliver a powder, an actuator to move the dispensing system along a scan axis, and an energy source to fuse a portion of the powder. The dispensing system has a hopper to hold the powder and a dispenser. The dispenser includes a channel extending along a longitudinal axis from a proximal end to a distal end. The proximal end of the channel of the dispenser is configured to receive the powder from the powder source. A powder conveyor is positioned within the channel to move the powder from the proximal end along a length of the channel, and a plurality of apertures are arranged along the longitudinal axis of the channel. The dispenser is configured such that flow of powder through each aperture is independently controllable.
