Abstract: A method of laser processing a material to form a separated part. The method includes focusing a pulsed laser beam into a laser beam focal line, viewed along the beam propagation direction, directed into the material, the laser beam focal line generating an induced absorption within the material, the induced absorption producing a hole or fault line along the laser beam focal line within the material, and directing a defocused carbon dioxide (CO2) laser from a distal edge of the material over the plurality of holes to a proximal edge of the material.

Abstract: 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.

Abstract: Strengthened glass articles having laser etched features, electronic devices, and methods of fabricating etched features in strengthened glass articles are disclosed. In one embodiment, a strengthened glass article includes a first strengthened surface layer and a second strengthened surface layer under a compressive stress and extending from a first surface and a second surface, respectively, of the strengthened glass article to a depth of layer, and a central region between the first strengthened surface layer and the second strengthened surface layer that is under tensile stress. The strengthened glass article further includes at least one etched feature formed by laser ablation within the first surface or the second surface having a depth that is less than the depth of layer and a surface roughness that is greater than a surface roughness of the first surface or second surface outside of the at least one etched feature.

Abstract: Processes of chamfering and/or beveling an edge of a glass or other substrate of arbitrary shape using lasers are described herein. Three general methods to produce chamfers on glass substrates are disclosed. The first method involves cutting the edge with the desired chamfer shape utilizing an ultra-short pulse laser. Treatment with the ultra-short laser may be optionally followed by a CO2 laser for fully automated separation. The second method is based on thermal stress peeling of a sharp edge corner, and it has been demonstrated to work with different combination of an ultrashort pulse and/or CO2 lasers. A third method relies on stresses induced by ion exchange to effect separation of material along a fault line produced by an ultra-short laser to form a chamfered edge of desired shape.

Abstract: Methods are provided for laser processing arbitrary shapes of molded 3D thin transparent brittle parts from substrates with particular interest in substrates formed from strengthened or non-strengthened Corning Gorilla® glass (all codes). The developed laser methods can be tailored for manual separation of the parts from the panel or full laser separation by thermal stressing the desired profile. Methods can be used to form 3D surfaces with small radii of curvature. The method involves the utilization of an ultra-short pulse laser that may be optionally followed by a CO2 laser for fully automated separation.

Abstract: Forming holes in a material includes focusing a pulsed laser beam into a laser beam focal line oriented along the beam propagation direction and directed into the material, the laser beam focal line generating an induced absorption within the material, the induced absorption producing a defect line along the laser beam focal line within the material, and translating the material and the laser beam relative to each other, thereby forming a plurality of defect lines in the material, and etching the material in an acid solution to produce holes greater than 1 micron in diameter by enlarging the defect lines in the material. A glass article includes a stack of glass substrates with formed holes of 1-100 micron diameter extending through the stack.
