Additive manufacturing of glass allows the fabrication of complex structures and geometries that traditional approaches cannot achieve. However, current strategies for 3D printing glass require thermal processes over 1000 °C to produce functional parts. We describe the development of low temperature process to 3D print glass and multimaterial composite glasses based on metastable silicate chemistry. The direct-write deposition process occurs at room temperature and the curing process only requires 250°C to achieve a stable glass structure. The properties of the printed glass can further be tailored in a plug-and-play fashion by introducing functional filler materials such as conductive particles. This straight-forward strategy will enable the fabrication of a wide variety of microfluidic, electronic, and radio frequency devices with higher thermal stability without the need for extensive thermal processing.
