G3DP is a manufacturing platform designed to 3D print transparent glass developed by researchers at MIT.
Not only that: it can make them graduated by varying their thickness and also modify through other steps the degree of opacity of a glass and its color, the index of transmission, reflection and refraction of light, and all the other parameters specific to any type of glass.
The platform is based on a thermal printer with two heating chambers: the upper one acts as an oven and a "toner", the lower one serves to temper the glass produced. The system operates at a temperature of over 1000 degrees centigrade and can create a single product with each cycle. The molten material passes through a nozzle with aluminum and silica, strengthening itself.
It is a robotic "master glassmaker": an ancient art that can find applications and creations unimaginable until now.
