Glass is a material with a long history, but today it still has a lot of practical properties, including electrical insulation, thermal insulation and unparalleled optical transparency. However, making custom structures, especially using high purity glass (such as fused silica glass), is not an easy task because it requires higher processing temperatures and some add hazardous chemicals.
In the past few years, 3D printing technology has become cheaper and has a wider range of applicable materials. But if you want to use standard 3D printing technology to create high quality glass structures that can be used in precision optical equipment, it is still a big problem.
This time, Bastin Rapp, a researcher at the Karlsruhe Institute of Technology in Germany, and his colleagues invented a new technology that overcomes this problem by using free-flowing quartz nanocomposites in standard 3D printers. Known as "liquid glass"), complex shapes are formed and then thermally processed to form a fused silica glass structure with higher optical properties. These structures are both smooth and transparent, and the detail features can be as small as tens of microns.
The technology is not just about providing beautiful crafts, but also creating surfaces with sufficient transparency and reflectivity for use in a wide range of optical devices.
The editor-in-chief glass is one of the oldest known materials and can be used for 21D century 3D printing technology. Looking at the material world, is it necessarily one or two? The pursuit of new materials such as graphene has created a trillion-dollar market; a new understanding of old materials can also promote mature industries, â€œnew day, new day, new dayâ€. It is the "magic wand" of technological advancement that has the infinite charm of 1+1>2.
