The world of 3D-printing is expanding day-by-day. Thanks to researchers from MIT, 3D-printing is taking a jump into the world of glass. Believe it or not, molten glass is the latest part of 3D-printing that MIT believes will change the world. 

Researchers published their findings in the 3D Printing and Additive Manufacturing journal. Not only does the system they created offer control over the hot glass material, but it creates a state-of-the-art final product. The combination of additive manufacturing with molten glass "presents a potential path toward production of highly complex geometry and custom-designed objects while retaining the optical transparency and chemical stability available through traditional manufacturing processes," the research states.The MIT researchers call the new printer G3DP2. 

The G3DP2 platform, has been used to turn molten glass into 3-meter tall columns exhibited in Milan.
