Russian-made 3D printer 'real'

Russian biologists and physicists have successfully created nanoparticles that enable 3D printing of objects of all shapes and sizes using conventional infrared lasers.

Installation instructions for this 3D printer based on the invention are published in the journal Scientific Reports.

So far, the scientific community has invented dozens of 3D printers capable of printing in all materials, from ordinary plastics to living cells and molten metal. However, all of these printers have not resolved two limitations, namely the low resolution and slow print speeds of existing 3D printers in a multilayered format.

Scientists have created nanoparticles that convert ultraviolet radiation into ultraviolet light.

Scientist Kirill Khaidukov of the Center for Crystallology and Optics of the Russian Academy of Sciences, one of the authors of the new patent, has addressed these limitations.

The authors created nanoparticles that convert ultraviolet radiation into ultraviolet light , which supports printing. Specifically, the team of Russian scientists used nanoparticles made of sodium, tullium, ytterbium and fluoride, which allowed it to 'shoot' ultraviolet light into the full thickness of the three-dimensional structure, while also using infrared radiation It is the source of energy, thus ensuring the ability to 'print' objects of all sizes.

According to Khaidukov, his group's invention can be applied to existing polymer materials, allowing the use of 3D printers in real time.

According to the authors' intentions, new inventions can be used in three-dimensional laser drawing, material processing, holography and three-dimensional imaging. object...
