Abstract: A method of fabricating a multi-color display includes dispensing a photo-curable fluid over a display having an array of LEDs disposed below a cover layer. The cover has an outer surface with a plurality of recesses, and the photo-curable fluid fills the recesses. The photo-curable fluid includes a color conversion agent. A plurality of LEDs in the array are activated to illuminate and cure the photo-curable fluid to form a color conversion layer in the recesses over the activated LEDs. This layer will convert light from these LEDs to light of a first color. An uncured remainder of the photo-curable fluid is removed. Then the process is repeated with a different photo-curable fluid having a different color conversion agent and a different plurality of LEDs. This forms a second color conversion layer in different plurality of recesses to convert light from these LEDs to light of a second color.

Abstract: A method of fabricating an object using an additive manufacturing system includes receiving data indicative of a desired shape of the object to be fabricated by droplet ejection. The desired shape defines a profile including a top surface and one or more recesses. Data indicative of a pattern of dispensing feed material is generated to at least partially compensate for distortions of the profile caused by the additive manufacturing system, and a plurality of layers of the feed material are dispensed by droplet ejection in accordance to the pattern.

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: Embodiments of the present disclosure relate to advanced polishing pads with tunable chemical, material and structural properties, and new methods of manufacturing the same. According to one or more embodiments of the disclosure, it has been discovered that a polishing pad with improved properties may be produced by an additive manufacturing process, such as a three-dimensional (3D) printing process. Embodiments of the present disclosure thus may provide an advanced polishing pad that has discrete features and geometries, formed from at least two different materials that include functional polymers, functional oligomers, reactive diluents, addition polymer precursor compounds, catalysts, and curing agents. For example, the advanced polishing pad may be formed from a plurality of polymeric layers, by the automated sequential deposition of at least one polymer precursor composition followed by at least one curing step, wherein each layer may represent at least one polymer composition, and/or regions of different compositions. Embodiments of the disclosure further provide a polishing pad with polymeric layers that may be interpenetrating polymer networks.

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 system. The energy delivery system has one or more light sources configured to emit a first light beam and a second light beam, and one or more reflective members each having reflective facets to redirect the first light beam or the second light beam toward an uppermost layer of feed material to deliver energy to the uppermost layer. The one or more reflective members are each rotatable such that motion of each sequential facet of the reflective facets of each of the one or more reflective members sweeps the first light beam along a first path on the uppermost layer or sweeps the second light beam along a second path on the uppermost layer.

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.
