METHOD AND SYSTEM FOR MAKING 3D GLASS, GLASS-CERAMIC AND CERAMIC OBJECTS

Abstract:

A apparatus for making a three-dimensional object that includes: a gripping fixture having a grip surface or a pedestal having a build surface, the grip or build surface configured to hold an end of a contiguous, preformed material; a feed system having a feed outlet 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 arranged to direct at least one laser beam through the furnace and into the build zone to form a hot spot in the build zone; and a positioning system 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 enclosing the build zone and the feed outlet.
