Glass making - Break Glass

The glass is finally cooled in a part of the machine called a lehr which is an important part of glass making since the glass can easily break if this is not controlled. The modern machines effect the glass making rate achievable, but this can be up to 75,000 light bulbs and 55,000 drinking glasses can be produced per day.


Additive manufacturing (AM) is useful in this regard as it facilitates the production of complex shapes without any prerequisite for molds and is cost effective when customization is important. 1, 2 Nevertheless, limited research has been conducted on AM of glass to date due to the challenges in glass processing.


A glass additive composition which consists of a carrier such as calcium carbonate, having an active material such as zinc selenite in combination with a surfactant and/or film forming material deposited thereon is an effective medium for introducing active materials into the glass manufacturing process and especially the manufacture of container glass.


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 ...

Additive Manufacturing

additive manufacturing processes, the 3D CAD solid must be mathematically split into the same layers as those produced physically by the AM machine. This process is known as "slicing." I There are two basic methods of doing this: 1) Triangulation, which leads to the STL format 2) Direct cutting in the CAD system, which leads to the CL (SLI) format
