Publication number: 20160339645Abstract: A 3D object (the “New Object”) is fabricated layer by layer by 3D printing. The shape and relative dimensions of the various parts of the New Object match that of another 3D object (the “Target Object”). In addition, the exterior of the New Object appears to be a photographic likeness of the Target Object. The “photographic” likeness is created by variations in visual characteristics of materials in the layers comprising the New Object, and in particular by variations at or near the surface of the New Object. Thus, the photographic likeness is an integral part of these layers comprising the New Object. An object is scanned, from which a texture map is obtained.

Publication number: 20160339646Abstract: In a method for printing a three-dimensional (3D) parts with an additive manufacturing system, a developed layer of an electrically charged powder material is produced on a transfer medium using an electrophotographic (EP) engine. The transfer medium and the developed layer are fed in a feed direction. A position of the developed layer on the transfer medium is detected using a first sensor having a first output that indicates the position. A position of a moveable build platform is adjusted relative to the transfer medium to reduce one or more overlay errors between the developed layer and an intermediate build surface of a three-dimensional structure retained on the moveable build platform based on the first output. The developed layer is transferred to the intermediate build surface using a pressing element.Type: ApplicationFiled: August 8, 2016Publication date: November 24, 2016Inventors: James Baecker, J.

Publication number: 20160339651Abstract: A composite article lay up comprising a first layer of resin impregnated fiber material and a second layer of resin impregnated fiber material. An open cell material is layered between the first layer and the second layer. The open cell material has no resin during a first stage of a resin cure cycle. The open cell material has passages configured to flow volatiles formed during the first stage of the resin cure cycle. The open cell material is configured to fill with the resin during a second stage of the resin cure cycle. The open cell material is configured to form an integral structure with the first layer and the second layer as part of the composite article at the completion of the resin cure cycle.Type: ApplicationFiled: December 16, 2014Publication date: November 24, 2016Inventors: Michael Parkin, Charles R Watson

Publication number: 20160339652Abstract: Systems and processes for enabling an off-site expert to interact with an on-site technician during repair of composite structure. The off-site expert can provide real-time guidance to an on-site technician before and during the performance of repair procedures to avoid errors. The off-site expert is also able to monitor the repair procedures in real time to verify that correct procedures are being employed. In particular, the systems and processes disclosed herein can provide direct visual guidance, feedback, and out-of-plan warnings for manual or automated scarfing and other operations during repair of composite structure. In some embodiments, the repair process combines optical three-dimensional surface measurement, illumination by at least one of visible, ultraviolet and infrared light, and digital light processing projection to provide step-by-step monitoring of the repair.Type: ApplicationFiled: May 21, 2015Publication date: November 24, 2016Applicant: THE BOEING COMPANYInventors: Morteza Safai, Gary E.
