Publication number: 20230321898Abstract: A method of making a workpiece in an additive manufacturing process includes determining a preferred angular orientation of the grid array about a build axis extending perpendicular to a layer to be built for a first layer of a workpiece. The preferred angular orientation is selected to align an edge of one or more pixels with an edge of the layer of the workpiece being built. The method further includes orienting a patterned image of radiant energy to the preferred angular orientation by rotating a projector before solidifying a portion of a resin that forms the first layer of the workpiece.Type: ApplicationFiled: June 13, 2023Publication date: October 12, 2023Inventors: Travis Gene Sands, Stephen Michael Deak

Patent number: 8091229Abstract: A procedure for repairing subsurface defects in a shell member laminate of a wind turbine blade includes detecting the location and boundary of the subsurface defect and drilling a fill hole from an external surface of the laminate into the defect proximate to a boundary of the defect. A vent hole is drilled from the external surface of the laminate into the defect proximate to an opposite boundary from the fill hole. A flowable bonding material is injected into the fill hole until the bonding material flows from the vent hole. The repair zone is reinforced with at least one mechanical fastener defined through the laminate either within the boundary of the defect or outboard of the boundary of the defect.Type: GrantFiled: March 8, 2011Date of Patent: January 10, 2012Assignee: General Electric CompanyInventors: Stephen Michael Deak, Scott Gabell Riddell
