Abstract: An additive manufacturing apparatus includes a platform, a dispenser to dispense a plurality of layers of feed material on a top surface of the platform, and an energy delivery assembly. The energy delivery assembly includes a light source to emit one or more light beams, a first reflective member having a plurality of reflective facets, and at least one second reflective member. The first reflective member is rotatable such that sequential facets sweep the light beam sequentially along a path on the uppermost layer. The at least one second reflective member is movable such that the at least one second reflective surface is repositionable to receive at least one of the at least one light beam and redirect the at least one of at least one light beam along a two-dimensional path on the uppermost layer.

Abstract: An additive manufacturing system includes a platen to support an object being manufactured, a dispenser to deliver a plurality of successive layers of a powder over the platen, and energy source configured to fuse at least a portion of the powder. The dispenser is configured to deliver the powder in a linear region that extends along a first axis. The dispenser and actuator are supported by a support structure, and the actuator is coupled to the support structure to move the support structure along a second axis perpendicular to the first axis such that the dispenser and energy source move as a single unit with the support structure and the linear region sweeps along the second axis to deposit the powder along a swath over the platen to form a layer of powder.

Abstract: A dispensing system for an additive manufacturing apparatus includes a frame, a powder reservoir, an agitator and an array of dispensing units positioned below the powder reservoir. The powder reservoir has a first width along a primary axis, and includes a lower portion and an upper portion that is wider than the lower portion along a second axis perpendicular to the primary axis. The agitator is positioned in the upper portion of the powder reservoir. Each dispensing unit includes a nozzle block that has a passage therethrough that defines a nozzle and provides a respective path for the powder to flow from the powder reservoir to the nozzle, and a valve positioned in the passage in the nozzle block to controllably release powder through the nozzle.

Abstract: A dispensing system for an additive manufacturing includes a powder source that contains powder to form an object, and an array of nozzles positioned at a base of the powder source over a top surface of a platen where the object is to be formed. The powder flows from the powder source through the nozzles to the top surface. A respective powder wheel in each nozzle controls a flow rate of the powder. Each wheel has multiple troughs on surface of the wheel. When a motor rotates the wheel, the troughs transport the powder through the nozzle. The rotation speed of the wheel controls the flow rate. For solid parts of the object, the wheel rotates and allows the powder to be deposited on the top surface. For empty parts of the object, the wheel remains stationary to prevent the powder from flowing to the surface.

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.

Abstract: A module for an additive manufacturing system includes a frame configured to be removably mounted on a movable support, a dispenser configured to deliver a layer of particles on a platen that is separate from the frame or an underlying layer on the platen, a heat source configured to heat the layer of particles to a temperature below a temperature at which the particles fuse, and an energy source configured to fuse the particles. The dispenser, heat source and energy source are positioned on the frame in order along a first axis, and the dispenser, heat source and energy source are fixed to the frame such that the frame, dispenser, heat source and energy source can be mounted and dismounted as a single unit from the support.
