Abstract: An additive manufacturing process includes forming an object material stack using sheet materials without use of binder material between the sheet materials and forming features of the cross-sectional layers of a 3D object in the corresponding sheet materials. Another process involves forming features of the cross-sectional layers of a 3D object in soot layers of a laminated soot sheet. A manufactured article includes three or more glass layers laminated together without any binder material between the glass layers. At least one of the glass layers is composed of silica or doped silica, and at least one feature is formed in at least one of the glass layers.

Abstract: Methods of strengthening the edge surfaces of a glass substrate, and particularly glass substrates contained within a display panel, are disclosed. The methods include exposing edges of the display panel to an acid solution for a time and at a temperature effective to remove no more than about 20 micrometers of glass from edge surfaces, rinsing the acid solution from the edge and applying a polymer protective coating the rinsed edge to maintain the post-etching strength of the edge surfaces. Electronics on the display panel that may be exposed to the acid solution are masked with a terminal mask prior to the etching. The edge etching may be combined with etching of a surface of the display panel/cover glass substrate.

Abstract: The invention relates to a burner module having a body that is either sintered or photo-cured, and to methods of making such a burner module. The body (110) of the burner (100) is formed from one of a sintered metal, a sintered alloy, a laminated glass ceramic, and a photo-cured polymer. 1 Sintering and photo-curing may be accomplished by irradiating the body with localized heating using a focused energy source, such as a laser. The burner module is resistant to thermal shock and provides a distributed, even stream of a precursor or precursors to be reacted in a flame of the burner module to form soot, which is to deposited on a receptor surface, and may be used for vapor and liquid precursor delivery systems. A soot deposition system having an array of such burner modules and methods of making a fused silica article by depositing soot using the burner modules are also described.
