    Glass: 3D printing is now done at low temperatures

    The researchers of MIT Lincoln Laboratory have developed an innovative method for 3D glass printing a low temperatures and to High performance, obtaining a material with unique electrical, optical and chemical properties.

    Reduction of temperature

    This is not the first case of 3D printing experimentation for glass, but the system devised by the Lincoln scientists involves a clear reduction in the temperature required for the process.
    In fact, glass post-processing usually involves exposure to temperatures close to 1000°C to produce an inorganic material. MIT's method instead involves layering a custom ink, which is curable a 250°C.

    The advantages of 3D printing

    In the article "Low Temperature Additive Manufacturing of Glass”, The team highlighted how emerging techniques for additive generation of inorganic structures have the potential to revolutionize the ceramic and glass industries.
    Our protagonist indeed offers important advantages through 3D printing, such as a better one biocompatibility and a major thermal stability.

    Focus on the nanocomposite

    The system developed by the researchers made it possible to eliminate the problem of high temperatures. The conclusion is in the nanocomposite used: a solution of sodium silicate, incorporated in functional nanoparticles and fumed silica nanoparticles to increase solubility.
    The combination of these three elements allows to carry out molding at low temperatures and to obtain a variety of materials, characterized by multiple characteristics. 
    The material also showed greater stability and resistance through the addition of a mineral oil bath to the polymerization process.

    Unlimited solutions and applications

    Scientists proposed “a modular system that can be tuned to print a wide variety of inorganic glasses with embedded functional nanomaterials (dielectrics, metallic and optical). This versatile material platform, when combined with multi-material additive manufacturing, will enable the fabrication of a wide variety of robust microsystems. " 

    It is a simple technique that optimizes the glass 3D printing process by voting it a many applications. The possibilities are almost endless: in fact, it could be possible to create high-performance glass surfaces or even glass capable of reacting to the environment, through shape-memory materials.
