    摘要： Push roll spools for engaging and driving softened glass tubes over a shaping mandrel. A push roll spool for use in processing a glass tube may comprise a base having first and second axially spaced ends, and multiple sheets of heat resistant material disposed on the base between the axially spaced ends, forming an axially extending stack. The stack may have a circumferential, generally U-section groove having a profile defined by the peripheral edges of multiple said sheets having different diameters. The U-section groove may be sized to engage and drive a glass tube. The U-section groove may have two contact areas at which to engage and drive a glass tube. The heat resistant material may comprise mica or a mica composition, for example mica paper or ceramic fiber millboard.

    摘要： A method for forming a structure includes providing a glass or glass ceramic tubular structure (110) having an interior (150) and exterior surface (160) and at least a partially closed end region (140); heating the glass or glass ceramic tubular structure (110) to at least its softening point by: providing a laser beam; directing the laser beam (130) down the interior surface of the glass or glass ceramic tubular structure (110), at least some of the laser beam (130) directed at an angle greater than a predetermined incidence angle; and the laser beam (130) impinging on the closed end region (140) where at least some of the laser beam (130) is absorbed by the closed end region (140) of the glass or glass ceramic tubular structure; and moving at least one of: the glass or glass ceramic tubular structure or the end region relative to each other to form at least a two-dimensional shape from the glass or glass ceramic tubular structure.

    摘要： 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.
