    摘要: An apparatus for dispensing hot glass during 3D printing includes a crucible with a cylindrical barrel open at a proximal end and an aperture at a distal end, a holder-actuator to hold a glass rod feedstock and move the feedstock into and within the barrel, a first heater on or adjacent the outer surface of the barrel, and a second heater on or adjacent the outer surface of the barrel energized independently, and positioned proximally, of the first heater. A method of dispensing glass during 3D printing includes feeding a glass rod feedstock into the proximal, open end of a crucible having an aperture at its distal end while maintaining the crucible at a first position within a first temperature range and maintaining the crucible at second position, proximal of the first position, within a second temperature range lower than the first temperature range.

    摘要: In one embodiment, a pulling roll for drawing glass sheet in a down-draw process includes a shaft member and a compliant cover assembly positioned on the shaft member. The compliant cover assembly includes at least one traction disk positioned on the shaft member. The at least one traction disk includes an annular hub and a plurality of spring elements integrally formed with the annular hub. The spring elements project outward from the annular hub such that an end of each spring element is positioned radially outward from a base of each spring element and is circumferentially offset relative to the base of each spring element.

    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.
