3D Printing Materials: Glass

——————————

3D printing using glass is difficult because of the high temperatures required to melt the material used for 3D printing. Technologies for 3D printing using glass exist so far mainly in research labs and Universities.  Some of these efforts are described below.

In 2009, researchers at Solheim Rapid Manufacturing Laboratory of University of Washington developed a process called Vitraglyphic.  In this process powdered glass is mixed with an adhesive materials and loaded into a 3D printer.  A binder is deposited into the powdered mixture and used for 3D printing shapes.  These shapes were put in a kiln so that the layers of glass fuse and create a solid glass object.  The team used similar procedure to 3D print ceramics objects.

In another effort, researchers led by Professor Neri Oxman of MIT’s Mediated Matter Group developed a 3D printer that extrudes molten glass.  The 3D printer maintains a nozzle through which the glass is extruded at temperatures of about 1,900 degrees Fahrenheit. This is significantly higher than the temperatures used for other 3D printing, for example, plastic.

An Israel based company Micron3DP has also announced that they have developed an extruder that can 3D print using molten glass at temperatures as high as 1640 degrees celsius.

MIT Develops Platform for 3D Printing Glass

—————————————————————-

Mediated Matter Group of MITs’ Media Lab in collaboration with MIT’s Department of Mechanical Engineering and MIT’s Glass Lab has developed an additive manufacturing platform called G3DP for printing transparent glass structures.  The G3DP platform uses two chambers, an upper chamber and a lower chamber.  The upper chamber is heated to a temperature of 1900°F to produce molten glass.  The lower chamber performs annealing by slowly cooling the molten glass.  The molten glass is funneled through a nozzle to 3D print fascinating glass structures.

According to Prof. Neri Oxman of the MIT Media Lab who directs the Mediated Matter research group, this research could lead to advances in creating fiber optic cables that transmit data more efficiently.
