Patent number: 10647060Abstract: A method of manufacturing three-dimensional (3D) objects is provided. The method includes generating a plan for printing a plurality of 3D objects in a 3D printing medium at least in part by identifying an unprinted area of the 3D printing medium for insertion of a cooling device and determining where at least some of the plurality of 3D objects are to be printed in the 3D printing medium such that none of the at least some of the plurality of 3D objects, when printed, intersect the identified unprinted area for the insertion of the cooling device. The method further includes printing, using a 3D printer, the at least some of the plurality of 3D objects in accordance with the plan and, after the printing, inserting the cooling device into the unprinted area of the 3D printing medium and cooling the 3D printing medium using the cooling device.Type: GrantFiled: November 23, 2016Date of Patent: May 12, 2020Assignee: Shapeways, Inc.Inventor: William Carter Davis

Patent number: 10647061Abstract: A method of forming a three dimensional (3D) object is disclosed. The method may involve providing a volume of photo-curable resin contained within an optically transparent resin container, and simultaneously directing optical projections from an optical subsystem at a plurality of angles ? through the volume of photo-curable resin. The optical beams are directed about a z axis extending through the volume of photo-curable resin. Each of the projections is provided with a calculated 2D spatial intensity function which creates a 3D intensity map. The projections act over a fixed temporal exposure period, during which the net exposure dose is sufficient to cure select portions of the volume of photo-curable resin, and to leave other portions uncured, to form a desired 3D part.Type: GrantFiled: May 12, 2017Date of Patent: May 12, 2020Assignees: Lawrence Livermore National Security, LLC, The Regents of the University of CaliforniaInventors: Brett Kelly, Robert Panas, Maxim Shusteff, Christopher Spadaccini, Hayden Taylor, Indrasen Bhattacharya

Patent number: 10647062Abstract: A method and a device for heat sealing multiple plies of a laminate from which gable top packaging can be produced, wherein the laminate has a carrier layer made of electrically non-conductive material and a sealing layer made of thermoplastic material on at least one surface of the laminate. To heat seal multiple plies of a laminate in a high-frequency alternating electric field, the alternating electric field is generated by a first lead of an HF voltage supply in a first sub-region of the sealing region and is generated by a second lead of the HF voltage supply, differing from the first lead, in at least a second sub-region of the sealing region, so that a different heat distribution is obtained over the sub-regions of the sealing region.Type: GrantFiled: May 13, 2015Date of Patent: May 12, 2020Assignee: ELOPAK ASInventors: Martin Mach, Thomas Böhme, Sebastian Mikulski

Patent number: 10647064Abstract: An apparatus for use in a friction stir operation, such as friction stir welding (FSW) or friction stir processing (FSP). The apparatus may have a rotating tool adapted to be plunged into a material, where the material is susceptible to being softened by heating. The rotating tool may further be adapted to be advanced along a surface of the material. An optical energy generating subsystem may be used to heat a portion of the material using optical energy as the tool is advanced along the material.Type: GrantFiled: October 16, 2012Date of Patent: May 12, 2020Assignee: Lawrence Livermore National Security, LLCInventors: Joseph C. Farmer, Alexander M. Rubenchik, Raymond J. Beach, Robert J. Deri, Edward I. Moses, Bassem S. El-Dasher, Sarath K. Menon, Terry McNelley

Patent number: 10647065Abstract: A method of making a composite article involves first forming an intermediate substrate. The intermediate substrate can be formed from fibers and an uncured thermoset polymer composition followed by partial cure, or from fibers and an uncured thermoset polymer composition followed by cure of the thermoset polymer composition and deposition of a thermoplastic on the surface of the substrate, or from fibers and an uncured thermoset polymer composition followed by cure and exposure of the substrate to organic solvent, a plasticizer, moisture, and/or heat. The intermediate substrate prepared according to any of the above techniques is then subjected to cold gas spray deposition to deposit a metal layer onto the intermediate substrate. In the case where the substrate was formed by partially curing a thermoset polymer composition, the metal-coated partially-cured thermoset polymer substrate is then fully cured.Type: GrantFiled: July 31, 2015Date of Patent: May 12, 2020Assignee: SIKORSKY AIRCRAFT CORPORATIONInventors: Justin B. Alms, Eric J. Amis, Joseph J. Sangiovanni, Ellen Y. Sun, Aaron T. Nardi

Patent number: 10647068Abstract: A composite material molding method is provided for forming a composite material. The molding includes disposing a reinforcing base material in a cavity inside an openable and closable mold, injecting resin into the cavity in a state in which a clamping pressure is exerted on the mold and curing the resin. When injecting the resin into the cavity, the injection pressure of the resin is adjusted between a first pressure that is higher than the clamping pressure and a second pressure that is lower than the clamping pressure, and the injection pressure of the resin is lowered from the pressure that is higher than the clamping pressure to the pressure that is lower than the clamping pressure at least once. The resin is thereby injected such that the pressure inside the cavity does not exceed the clamping pressure from the start of injection to the end of injection of the resin.Type: GrantFiled: October 22, 2014Date of Patent: May 12, 2020Assignee: Nissan Motor Co., Ltd.Inventor: Katsuhiro Usui
