Russia creates "real" 3D printer
Russian biologists and physicists have successfully created nanoparticles that allow three-dimensional (3D) printing of objects of any shape and size using a conventional infrared laser.
Instructions for assembling a 3D printer based on this invention are published in the journal Scientific Reports.
To date, scientists have invented dozens of 3D printers capable of printing with all materials, from conventional plastics to living cells and molten metals. However, all of these printers have not solved two limitations, which are low resolution and slow printing speed because current 3D printers all print using a multi-layer mechanism.
Scientists have created nanoparticles that can convert infrared radiation into ultraviolet rays.
Scientist Kirill Khaidukov of the Center“Crystallinity and Optics”The Russian Academy of Sciences, one of the authors of the new invention, has solved the above limitations.
The team of authors created nanoparticles that can convert infrared radiation into ultraviolet rays, supporting the printing process. Specifically, the group of Russian scientists used nanoparticles made from sodium, tullium, ytterbium and fluorine, allowing them to "shoot" ultraviolet rays into the entire thickness of the three-dimensional structure, while using infrared radiation as an energy source, thereby ensuring the ability to "print" objects of all sizes.
According to Mr. Khaidukov, his team's invention can be applied to existing polymer materials, allowing 3D printers to be used in practice immediately.
According to the authors' intention, the new invention can be used in 3D laser drawing, material microprocessing, holography and the technique of capturing and reconstructing 3D images of objects...
