Abstract:
A nozzle deposits a filament of viscous, molten glass onto a print bed, while the print bed rotates about a vertical axis and translates in x, y, and z directions. The deposition is computer controlled, such that the resulting deposited filament forms a desired glass object that is solid after it anneals. One or more motors rotate the print bed such that the direction of deposition of the molten glass is constant relative to the nozzle, even though the print bed is translating in different directions relative to the nozzle. Keeping the direction of deposition constant relative to the nozzle tends to prevent the extruded filament of molten glass from experiencing large, changing, tensile and shear forces that would otherwise occur and that would otherwise damage the filament.
