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.

A method of forming a dissolvable part of amorphous borate includes: preparing a mixture comprising one or more boron compounds and one or more alkali compounds, at least one of the one or more boron compounds and the one or more alkali compounds being hydrous; heating the mixture to a melting temperature for a predetermined time to melt the mixture and release water from the mixture to form an anhydrous boron compound that is moldable, wherein the amount of alkali compound being selected to achieve an alkali oxide content of between about 10 to 25%; with the anhydrous boron compound at a molding temperature, molding the anhydrous boron compound in a mold; and cooling the anhydrous boron compound to form a solid.

A printing apparatus for 3D printing of feedstock. The printing apparatus comprises a hollow nozzle having an inlet and an outlet. The nozzle is mounted within a heating body that holds and heats the nozzle whereby the feedstock passing through the nozzle is heated prior to exiting the outlet. The nozzle can be mounted within the heating body such that an exterior surface of a portion of the nozzle locates outside of and extends away from the heating body to be exposed to ambient atmosphere. As a result, the temperature of the nozzle can vary across the nozzle.

A device for forming a molten solidified body by receiving a molten material discharged from a vitrification device or the like on a lower mold, and a method for forming a molten solidified body and, particularly, to a mold supporting device for forming a uniform molten solidified body such that a height deviation on a mold of a dropping molten material is reduced by providing movement to the mold, and a method for forming an uniform molten solidified body. The mold supporting device and the method for forming a uniform molten solidified body to prevent the formation of a high columnar shape at a specific position by the molten effluent not being uniformly contained in the mold due to the high viscosity thereof, thereby forming a uniform solidified body.
