Abstract: A glass article manufacturing system 20 includes a crucible 44. The crucible 44 includes a barrel 52 and a nozzle 60. The barrel receives a feedstock. A translational stage 92 is positioned below the nozzle of the crucible. The translational stage is movable. A heater 72 is in thermal communication with the nozzle such that thermal energy provided by the heater is transferred to the feedstock. A feeder assembly 32 is positioned proximate the barrel of the crucible such that the feeder assembly feeds the feedstock into the barrel. The translational stage may provide negative pressure to retain a build plate to the translational stage. A preformed component may be positioned on the translational stage.

Abstract: An apparatus for continuous electro-thermal poling of glass or glass ceramic material, includes a lower support conveying and contacting electrode structure, an upper contacting electrode structure positioned above the lower support structure, and one or more DC bias voltage sources connected to one or both of the upper contacting structure and the lower support structure. A process for continuous electro-thermal poling of glass or glass ceramic sheets or substrates includes heating the sheet or substrate, feeding the sheet or substrate continuously or continually, while applying a DC voltage bias, and cooling the sheet or substrate to within 0-30°C of ambient temperature.
