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: 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.

Abstract: 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.
