Patent number: 11773004Abstract: The present invention relates to a laser cutting technology for cutting and separating thin substrates of transparent materials, for example to cutting of display glass compositions mainly used for production of Thin Film Transistors (TFT) devices. The described laser process can be used to make straight cuts, for example at a speed of >0.25 m/sec, to cut sharp radii outer corners (<1 mm), and to create arbitrary curved shapes including forming interior holes and slots. A method of laser processing an alkaline earth boro-aluminosilicate glass composite workpiece includes focusing a pulsed laser beam into a focal line. The pulsed laser produces pulse bursts with 5-20 pulses per pulse burst and pulse burst energy of 300-600 micro Joules per burst. The focal line is directed into the glass composite workpiece, generating induced absorption within the material.Type: GrantFiled: March 23, 2016Date of Patent: October 3, 2023Assignee: CORNING INCORPORATEDInventors: Thomas Hackert, Xinghua Li, Sasha Marjanovic, Moussa N'Gom, David Andrew Pastel, Garrett Andrew Piech, Daniel Schnitzler, Robert Stephen Wagner, James Joseph Watkins

Patent number: 11065860Abstract: A method of printing a 3D object includes feeding one or more preformed materials from a feed outlet into a build zone in which a hot spot is located and using the hot spot to selectively heat the one or more preformed materials to a viscous state. Object layers are formed by depositing portions of the preformed materials on a build surface, or on another object layer on the build surface, while effecting relative motion between the build surface and the feed outlet.Type: GrantFiled: August 12, 2016Date of Patent: July 20, 2021Assignee: CORNING INCORPORATEDInventors: Christopher William Drewnowski, Michael Thomas Gallagher, Scott Michael Jarvis, Xinghua Li, Moussa N'Gom, Robert Stephen Wagner, Nicholas Ryan Wheeler

Patent number: 10513455Abstract: An apparatus includes a fiber feeding system to deposit a fiber on an edge of the glass article and a laser system. The laser system is positioned to project a first and a second laser beam onto a first and a second side of the fiber, respectively. The laser system is positioned to project a third laser beam onto the edge of the glass article. A method includes advancing a glass article relative to a fiber; positioning the fiber in relation to an edge of the glass article, contacting a first side of the fiber with a first laser beam, contacting a second side of the fiber with a second laser beam, depositing the fiber on the edge of the glass article, and contacting the edge of the glass article with a third laser beam.Type: GrantFiled: October 29, 2015Date of Patent: December 24, 2019Assignee: Corning IncorporatedInventors: Thomas Roger Cook, Christopher William Drewnowski, Peter Knowles, Geunsik Lim, Moussa N'Gom, Irene Mona Peterson, Robert Stephen Wagner

Publication number: 20190177203Abstract: Systems and methods for laser-cutting thermally tempered substrates are disclosed. In one embodiment, a method of separating a thermally tempered substrate includes directing a laser beam focal line such that at least a portion of the laser beam focal line is within a bulk of the thermally tempered substrate. The focused pulsed laser beam is pulsed to form a sequence of pulse bursts comprising one or more sub-pulses. The laser beam focal line produces a damage track within the bulk of the tempered substrate along the laser beam focal line. Relative motion is provided between the focused pulsed laser beam and the tempered substrate such that the pulsed laser beam forms a sequence of damage tracks within the tempered substrate. Individual damage tracks of the sequence of damage tracks are separated by a lateral spacing, and one or more microcracks connect adjacent damage tracks of the sequence of damage tracks.Type: ApplicationFiled: February 15, 2019Publication date: June 13, 2019Inventors: Moussa N'Gom, Garrett Andrew Piech, James Joseph Watkins, Kristopher Allen Wieland, Chad Michael Wilcox
