Patent number: 11318671Abstract: A web sheet processing system for cutting and/or stacking AM composite printed sheets from the web combines web edge waste with the cut sheets, stacking the waste with the 3D object. The waste may be removed during the cleaning of the 3d object (e.g., by abrasive blasting, chemical removal, dissolution) to result in a 3D printed object. This approach eliminates the separate need for waste removal of a rewound web of substrate material waste. In examples, a tractor drive transport assembly ensures consistent web/sheet motion via tractor feeding along the edges of the web/sheet to a stacker subsystem. The tractor drive transport assembly, in combination with a drive guide, positions the cut sheets over the stacker subsystem for release onto the top of a stack, with the substrate waste that would normally be processed downstream stacked with the 3D object for removal during a normal cleaning of the object.Type: GrantFiled: May 21, 2019Date of Patent: May 3, 2022Assignee: Xerox CorporationInventors: Paul N. Richards, Paul M. Fromm

Patent number: 11214000Abstract: An additive manufacturing system for fabricating multi-sided printed composite sheet structures includes a roll fed duplex architecture that prints polymer images on both sides of a substrate sheet to form two-sided 3D composite layers. A substrate web is fed into the machine, and a top side is printed with a wetting agent, powdered, and the excess powder is removed. The image may be pinned to the substrate in a fusing step so that the web can be inverted to print a second image on the other side. The inversion architecture could include inverting rollers, tubes or a Mobius strip that may flip the substrate for backside printing using a single imaging station. The resulting two-side powdered and pinned substrate would then be cut, stacked, heated and compressed to create a 3-D object with more polymer in the stack, resulting in better adhesive binding characteristics at a much higher production speed.Type: GrantFiled: April 3, 2019Date of Patent: January 4, 2022Assignee: Xerox CorporationInventors: Marc D. Daniels, Jeffrey W. Drawe, James J. Spence, Paul M. Fromm, Paul N. Richards

Patent number: 8905662Abstract: Methods and devices include a patterning device positioned along a processing path. The patterning device forms one or more holes through workpieces at a contact location of the workpieces. A transport device is positioned along the processing path. The transport device removes the workpieces from the processing path and stacks the workpieces by simultaneously moving at least two of the workpieces together in workpiece sets. The transport device comprising a vacuum device that contacts the contact location of the top workpiece within each of the workpiece sets. The vacuum device applies vacuum through the holes of the top workpiece to the bottom workpiece within each of the workpiece sets to maintain the workpieces together in the workpiece sets when performing the removing and the stacking.Type: GrantFiled: August 16, 2011Date of Patent: December 9, 2014Assignee: Xerox CorporationInventors: Paul N.
