In the academic journal with the highest world influence factor, Nature has published a new technology that uses light-cured 3D printing technology to print and shape silica mixed photosensitive materials. After degreasing and firing, transparent glass is obtained.
This technical process will undoubtedly have a profound impact on the current optical glass and ordinary glass industry.
Please see the detailed technical process below.
Not long ago, the Karlsruhe Institute of Technology in Germany achieved a striking breakthrough in glass 3D printing technology. By using a new nanocomposite, they printed transparent and resistant with the most common light-curing (SLA) 3D printer. Heat, shock resistant, high quality silica glass. Even better, these glasses can have extremely complex shapes and very small sizes. Below, the Antarctic bear is introduced in detail:
As mentioned earlier, the most critical part of this breakthrough is the use of a new nanocomposite. It is reported that the material is composed of amorphous silica (quartz) particles with an average diameter of 40 nm and a liquid polymer that can be cured by ultraviolet rays, and the optical transmission rate is as high as 66% at a wavelength of 365 nm. In comparison, the average cast nanocomposite is only 4%.
