Antireflection coating for 3D printers

Anti-reflective glass ensures precise UV light focusing and protects the laser optics of the Nd:YAG laser

Precision light in 3D printers:

Filters with antireflection coating of specific wafe lenghts support UV radiation or protect laser optics

Surrounded by flat glass with an anti-reflective coating for corresponding wavelengths, the printed plastic or metal object grows – layer by layer. The incident photons stimulate the chemical process that causes 3D prints to harden. The necessary UV radiation, precisely focused by the optics, can freely penetrate the nanoscale coated filter glass. This ensures optimal radiation, which accelerates the digitalised print-on-demand process.
The process is used for the production of prototypes, models and moulds in dental technology as well as in the jewellery industry.

Anti-reflective filter glass is also used for printing metal objects. Our filter glass protects the laser optics reliably while enabling the highest transmission rates. These laser optics focus the radiation emitted by a Nd:YAG laser with a wavelength of 1064 nm with pinpoint accuracy and thus effect the micro-melting process of the respective metal powder.
