摘要： Glass articles including one or more 3D printed surface features attached to a surface of a substrate at a contact interface between the 3D printed surface feature and the surface. The 3D printed surface feature(s) include a glass or a glass-ceramic, a compressive stress region at an exterior perimeter surface of the 3D printed surface feature(s), and a central tension region interior of the compressive stress region. The 3D printed surface feature(s) may be formed of a contiguous preformed material 3D printed on a surface of a substrate. The compressive stress region of a 3D printed surface feature may be formed using an ion-exchange process.

摘要： An apparatus for forming glass tubing is described. The apparatus for forming glass tubing comprises an endless former with an outer surface and an inner passage defining an inner surface. The apparatus for forming glass tubing further comprises two chambers from which molten glass may flow. One chamber flows molten glass to the outer surface of the endless former and another chamber flows molten glass to the inner surface of the endless former. The two flows of molten glass meet at the bottom of the former to form glass tubing.

摘要： A method of making a glass sheet comprises laminating a high CTE core glass to a low CTE clad glass at high temperatures and allowing the laminate to cool creating compressive stress in the clad glass, and then ion exchanging the laminate to increase the compressive stress in the outer near surface regions of the clad glass. The core glass may include ions that exchange with ion in the clad glass to increase the compressive stress in inner surface regions of the clad glass adjacent to the clad glass/core glass interfaces. The glass laminate may be formed and laminated using a fusion forming and laminating process and fusion formable and ion exchangeable glass compositions.

摘要： A method includes heating a glass preform having a plurality of glass layers and drawing the glass preform in a distal direction to form a drawn glass sheet extending distally from the glass preform and having the plurality of glass layers. The drawn glass sheet is thinner than the glass preform. The drawn glass sheet can be rolled onto a collection spool. At least a portion of a glass layer can be removed from the drawn glass sheet. An exemplary glass sheet includes a first glass layer, a second glass layer adjacent to the first glass layer, and a thickness of at most about 0.1 mm. An exemplary ion exchanged glass sheet includes a thickness of at most about 0.1 mm and a surface layer that is under a compressive stress and extends into an interior of the glass sheet to a depth of layer.

摘要： In one embodiment, a pulling roll for drawing glass sheet in a down-draw process includes a shaft member and a compliant cover assembly positioned on the shaft member. The compliant cover assembly includes at least one traction disk positioned on the shaft member. The at least one traction disk includes an annular hub and a plurality of spring elements integrally formed with the annular hub. The spring elements project outward from the annular hub such that an end of each spring element is positioned radially outward from a base of each spring element and is circumferentially offset relative to the base of each spring element.

摘要： A glass substrate with modified surface regions is disclosed. The glass substrate includes an alkali-containing bulk, a first alkali-depleted region, a second alkali-depleted region, and a first ion-exchanged region. The alkali-containing bulk has a first surface and a second surface with the first and second surfaces on opposite sides. The first alkali-depleted region extends into the alkali-containing bulk from the first surface. The second alkali-depleted region extends into the alkali-containing bulk from the second surface. The first ion-exchanged region extends into the alkali-containing bulk from the first surface. The first alkali-depleted region, the second alkali-depleted region, and the first ion-exchanged region each have a substantially homogenous composition. A method of forming the glass substrate is disclosed. The method includes simultaneously forming the first alkali-depleted region and the first ion-exchanged region in the first surface. The method also includes near-simultaneously forming the second alkali-depleted region in the second surface.
