Abstract: A glass substrate according to one or more embodiments is disclosed. The glass substrate includes an alkali-containing bulk, at least one first alkali-depleted region, and at least one second alkali-depleted region. The alkali-containing bulk has a first surface and a second surfaces with the first and second surfaces opposing one another. The at least one first alkali-depleted region extends into the alkali-containing bulk from the first surface. The at least one second alkali-depleted region extends into the alkali-containing bulk from the second surface. The first alkali-depleted region and the second alkali-depleted region are amorphous and have a substantially homogenous composition. The first alkali-depleted region in some embodiments is a first alkali-depleted surface layer that extends across the alkali-containing bulk. The first alkali-depleted region in some embodiments is plurality of first alkali-depleted regions that are spaced apart from one another.

Abstract: A apparatus for making a three-dimensional object (glass, glass ceramic or ceramic) that includes: a gripping fixture 102a having a grip surface or a pedestal 102 having a build surface 130, the grip or build surface configured to hold an end of a contiguous, preformed material 106, such as a fiber or a ribbon; a feed system 100 having a feed outlet 118 positioned above the grip or build surface, the feed system configured to feed the contiguous, preformed material into a build zone between the feed outlet and the grip or build surface; and a laser delivery system 134 arranged to direct at least one laser beam through the furnace 132 and into the build zone to form a hot spot 126 in the build zone; and a positioning system 120 arranged to effect relative motion between the grip or build surface and the feed outlet. In some implementations, the apparatus for making a 3D object can also include a furnace 132 enclosing the build zone and the feed outlet.

IPC: C03C23/00
Abstract: An apparatus for continuous electro-thermal poling of glass or glass ceramic material, includes a lower support conveying and contacting electrode structure, an upper contacting electrode structure positioned above the lower support structure, and one or more DC bias voltage sources connected to one or both of the upper contacting structure and the lower support structure. A process for continuous electro-thermal poling of glass or glass ceramic sheets or substrates includes heating the sheet or substrate, feeding the sheet or substrate continuously or continually, while applying a DC voltage bias, and cooling the sheet or substrate to within 0-30° C. of ambient temperature.
