The present invention relates to an additive manufacturing method and apparatus for forming a three-dimensional component/object of glass including the steps of: feeding a glass filament material in an essentially horizontal direction towards a stage, heating the glass filament material such that the glass fiber material becomes or remains molten/softened; and depositing the molten/softened glass material onto a surface of the stage or object, in which the molten/softened glass material is forming the three-dimensional component/object of glass; wherein during at least part of the depositing the three-dimensional component of glass being formed rests on an essentially vertical stage, the molten/softened glass material is deposited layer-by-layer and one or more computers control wherein each layer the molten/softened glass material is deposited, by controlling a set of actuators that actuate movement of the glass filament and/or the stage.

It is difficult to obtain a glassy, monolithic molded body of an inorganic oxide with a high melting point and softening point. Although molding by sintering is possible, it is hard to obtain a molded body which is transparent and has high barrier properties. Further, producing molded bodies with the sol-gel process is costly, and it is difficult to produce a molded bodies of large size. In this invention, a molded body principally composed of inorganic oxides is produced with a method that involves a step in which an inorganic-organic hybrid compound, formed by an organic polymer having a hydroxyl group chemically bonding with an inorganic oxide or a derivative thereof, is heated in an atmosphere in which oxygen is present, and the organic polymer component of the inorganic-organic hybrid compound is oxidized and removed.

Provided is a method for producing a glass material whereby a glass material less likely to undergo solarization can be obtained. A method for producing a glass material includes the steps of: preparing a glass; and subjecting the glass to heat treatment for six or more hours at a temperature of not lower than (Tg?70?) C and not higher than (Tg+40?) C where a glass transition point of the glass is represented as Tg (? C.).

In illustrative implementations of this invention, a crucible kiln heats glass such that the glass becomes or remains molten. A nozzle extrudes the molten glass while one or more actuators actuate movements of the nozzle, a build platform or both. A computer controls these movements such that the extruded molten glass is selectively deposited to form a 3D glass object. The selective deposition of molten glass occurs inside an annealing kiln. The annealing kiln anneals the glass after it is extruded. In some cases, the actuators actuate the crucible kiln and nozzle to move in horizontal x, y directions and actuate the build platform to move in a z-direction. In some cases, fluid flows through a cavity or tubes adjacent to the nozzle tip, in order to cool the nozzle tip and thereby reduce the amount of glass that sticks to the nozzle tip.
