A liquid silica resin (LSR) developed by researchers at the University of Arizona has proven successful as a 3D-printing medium for complex micro-optics. The organic-inorganic hybrid material has shown high curing speeds, better mechanical properties, lower thermal treatment temperatures, and reduced shrinkage. Inorganic silica glass can be achieved by thermally treating the printed sample at 600 °C in air. For the 3D-printing of optics and micro-optics, the silica resin is an alternative to organic polymers. Despite their lightweight and low-cost qualities, organic polymer-based...Read full articleRelated content from Photonics MediaARTICLESContinuous-Wave Diodes Shrink Size, Cost of 3D Laser PrintersCompact desktop printers could soon take the place of big, expensive laser printers for printing 3D micro- and nanostructures.

The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation.
