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.

A glass composite includes a first glass member and a second glass member. The first glass member and the second glass member are at least partially connected with each other at the surfaces, and a contact interface is formed on the contacting position of the first glass member and the second glass member. The contact interface is visually observed to have no crevices; and when the glass composite is in contact with an acid solution, crevices are suitably formed in the glass composite at the contact interface.

An electronic device that can be worn on the body or introduced into the body includes: a casing having a top and a bottom and an inorganic support including an opening and composed of a plurality of components; and at least one window made of at least one of glass or glass ceramic provided on the bottom. The window is secured in the inorganic support and seals the opening in the inorganic support.

A method of manufacturing a cover glass is provided. The method comprises providing a glass base; forming a glass support portion by printing glass onto the glass base; and applying glass wool onto the glass support portion.

Method and system for a laser welding process employing the use of a single pulsed fiber laser source configured to generate a radiative output with a wavelength spectrum extending from about 1.8 microns to about 2.6 microns. In a specific case, the laser output from the single pulsed fiber laser source is focused onto the interface of the two pieces of materials at least one of which includes any of glasses, inorganic crystals, and semiconductors.

A method for making a vacuum insulated glass window assembly is provided in which an amount of wet frit material is applied to a lower portion of a pump-out tube prior to insertion of the tube into a hole formed in a glass substrate of the VIG window assembly. The tube is then inserted into the hole, frit paste end first. An amount of frit may overflow the hole and form a bump/shoulder of frit material proximate the area of the hole on an outer surface of the glass substrate. Applying the fit to the tube prior to insertion and at a lower portion thereof reduces the amount of and/or avoids residual frit being deposited in an area of the tube that might significantly interfere with subsequent sealing processes, such as, for example, laser sealing of the pump-out tube.

Various embodiments comprise a laser bonded glass-silicon vapor cell for performing spectroscopy on particles like atoms or molecules. In some examples, the laser bonded glass-silicon vapor cell comprises a glass base, a glass top, a silicon piece, and a filling material. The silicon piece comprises at least one through hole. The lower surface of the silicon piece is hermetically bonded to the glass base. The upper surface of the silicon piece is laser bonded to the glass top. The filling material is positioned in a cavity formed by the through hole, the glass base, and the glass top. The filling material may comprise an alkali metal, a salt slush, or an inert gas. In some examples the cavity formed by the through hole, the glass base, and the glass top may comprise a vacuum encapsulation.
