In a groundbreaking development, researchers at MIT Lincoln Laboratory have pioneered a low-temperature additive manufacturing technique for 3D printing glass. This innovative method, announced recently, allows for the creation of intricate glass structures at a mere 250°C, a stark contrast to the high temperatures typically required.
The process utilizes a specially formulated ink, a blend of silicate solution and inorganic nanoparticles. This ink is precisely extruded layer by layer using direct ink writing, a form of 3D printing, to construct the desired object. The printed item is then cured in a mineral oil bath, causing the glass molecules to solidify.
This technology opens doors to complex geometries previously unattainable, while also being compatible with temperature-sensitive materials. Potential applications span microfluidic systems, optical lenses, and high-temperature electronic components, promising a revolution in design and manufacturing.
