Patent number: 11628626Abstract: Example systems relate to recoater movement. A non-transitory machine readable medium may contain instructions executable by a processor. The instructions may include instructions to change an action of a recoater in response to a determination that the recoater has reached a first location of a build area comprising build material. Instructions may further include instructions to lift the recoater in response to a determination that the recoater has reached a second location of the build area. Instructions may additionally include instructions to move the recoater over the second location at the lifted position, wherein the second location includes a build-up of the build material.Type: GrantFiled: April 21, 2017Date of Patent: April 18, 2023Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Brent Ewald, Michael Ewe, Eric Collins, Wesley R. Schalk

Patent number: 11628627Abstract: In an example, a method is described that includes generating a model for fabricating an item via an additive manufacturing process. The model includes a first region defining the item and a second region defining a sacrificial artifact whose presence disguises a physical characteristic of the item. The item and the sacrificial artifact are then fabricated in a common build batch via the additive manufacturing process.Type: GrantFiled: July 18, 2017Date of Patent: April 18, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Wei Huang, Steven J. Simske, Gary J. Dispoto

Patent number: 11628628Abstract: A method for manufacturing a composite part by laying up courses of composite tape using an automated tape layup (ATL) machine onto a conductive flexible facesheet laid flat on a flat surface, and then transferring the facesheet with the composite material thereon to a curved tooling surface for attachment of substructures and curing into the composite part. The method may also include applying insulation below the facesheet and above the composite material, then heating the conductive facesheet to cure the composite tape and fuse the composite tape to the substructures without heating the tooling surface or any other items used to compress and cure the composite material into the composite part. Heating of the facesheet may be performed using joule heat provided by a single turn transformer inducing current to a plurality of conductive wires attached at opposing ends to the facesheet.Type: GrantFiled: May 26, 2020Date of Patent: April 18, 2023Assignee: Spirit AeroSystems, Inc.Inventor: Mark Anthony Wadsworth
