Revolutionizing Glass 3D Printing: Low-Temperature Additive Manufacturing

Lincoln Laboratory has developed a groundbreaking low-temperature 3D printing technique for glass, eliminating the need for high-temperature sintering. Their process uses a custom multi-material glass ink and direct ink writing to create stable glass structures at just 250°C, a significant improvement over traditional methods requiring temperatures exceeding 1000°C. This innovative approach opens up possibilities for complex glass structures in microfluidic systems, freeform optics, and high-temperature electronics, overcoming cost and material limitations of traditional glass 3D printing. The resulting structures exhibit high resolution, thermal stability, and minimal shrinkage.
