Silica, which as the raw material of 3D printing, will be the bright spot of quartz powder industry growth
In recent years, the development of 3D printing technology is in full swing, and the technology is getting more and more advanced.
Over the past few years, technology has become cheaper and more widely available.Raw materials from organic, metal, to the present, inorganic materials directly as raw materials for 3D printing, has emerged.But making glass structures of high quality suitable for precision optical devices using standard 3D printing technology remains a challenge.?
German scientists have used standard 3D printing technology to create ultra-complex, sophisticated and high-quality glass structures, such as tiny kinky pretzels or castles, according to a study of materials science published in the British journal nature.The new technology means it is now possible to make structures with high optical properties using 3D printing technology, which can be widely used to design sophisticated lenses and filters.
Glass is a super-old material, and it's not easy to make custom structures, especially using high-purity glass, such as fused quartz, because of the high processing temperatures and sometimes the addition of hazardous chemicals.
How can 3D printing be used to create highly sophisticated glass structures?
Germany karlsruhe institute of technology (MIT) researchers buss, m. rapp, people invented a kind of new technology to overcome this problem, they can be used in standard 3 d printers to the free flow of silica nanocomposite (known as "liquid glass") to produce complex shapes, and then through the hot working process, formation with high optical performance of fused quartz glass structure.
The structures are smooth and transparent, with features as small as tens of microns.
Not only does the technology provide exquisite artware, it also produces surfaces that are transparent and reflective enough to be used in a wide range of optical devices.?
