Patent number: 11112771Abstract: An additive manufacturing system uses a trained artificial intelligence module as part of a closed-loop control structure for adjusting the initial set of build parameters in-process to improve part quality. The closed-loop control structure includes a slow control loop taking into account in-process build layer images, and may include fast control loop taking into account melt pool monitoring data. The artificial intelligence module is trained using outputs from a plurality of convolutional neural networks (CNNs) tasked with evaluating build layer images captured in-process and images of finished parts captured post-process. The post process images may include two-dimensional images of sectioned finished parts and three-dimensional CAT scan images of finished parts.Type: GrantFiled: December 15, 2018Date of Patent: September 7, 2021Assignee: Moog Inc.Inventors: Paul Guerrier, George Baggs

Publication number: 20170361377Abstract: An additive manufacturing system with a build chamber has a halide vessel that generates a halide gas and a dissociation chamber with a filament. Metal condensate is contacted with the halide gas to form a gaseous metal halide compound. The gaseous metal halide compound is decomposed to deposit metal on the filament. In an example, titanium reacts with gaseous iodine to form gaseous titanium tetraiodide.Type: ApplicationFiled: December 2, 2015Publication date: December 21, 2017Inventors: Paul Guerrier, Ian L. Brooks

Publication number: 20170246709Abstract: Byproduct condensate generated during additive manufacturing is controlled by providing at least one electrode inside a chamber. The condensate may be electrically charged as it is generated or an electrical charge may be imparted to the condensate. The electrode may have either a positive or negative bias to either attract or repel the condensate. The electrode may be located on a wall of the chamber or associated with a transparent window through which a laser beam passes into the chamber.Type: ApplicationFiled: September 17, 2015Publication date: August 31, 2017Inventors: Paul Guerrier, Ian L. Brooks

Patent number: 9695755Abstract: Methods and systems are provided for addressing pre-ignition occurring while operating with blow-though air delivery. A variable cam timing device used to provide positive intake to exhaust valve overlap is adjusted in response to an indication of pre-ignition to transiently reduce valve overlap. Pre-ignition mitigating load limiting and enrichment applied during a blow-through mode is adjusted differently from those applied when blow-through air is not being delivered.Type: GrantFiled: August 2, 2016Date of Patent: July 4, 2017Assignee: Ford Global Technologies, LLCInventors: Chris Paul Glugla, Robert Sarow Baskins, James Matthew Kindree, Paul A. Pietrzyk, Mark Paul Guerrier, Rama Sanghvi
