To make a great pizza, you need an oven temperature around 700 degrees Fahrenheit. To melt thermoplastics, like most of today’s fused filament 3-D printers, you want just over 220 degrees Fahrenheit. To melt glass, you need about three times that, over 2,100 degrees Fahrenheit (1165 degrees Celsius), roughly. The MIT Media Lab, with its Mediated Matter Research Group, has been doing more than a little tinkering to create the world’s first Glass 3-D printer.
