MIPT: Dry Aerosol Printer

History

2025: Product Announcement

In Russia, the world's first dry aerosol printer has been created, designed to form micro-sized metal structures in the production of microelectronics and photon components. The development was carried out by specialists from the Moscow Institute of Physics and Technology. According to the press service of the university, published in early April 2025, the presented equipment has no foreign analogues and can be used to produce new generation electronic equipment with a high degree of miniaturization.

The Russian device combines four technological processes in one device: synthesis of nanoparticles, their modification, printing with an aerosol beam and laser sintering of an array of nanoparticles on a substrate. This makes it possible to form microstructures with a line width of 30 to 400 micrometers with nanoparticles ranging in size from 50 to 300 nanometers.

The dry aerosol printer has a wide range of applications. It can be used to create microelectronics elements, form plasmon nanostructures in optoelectronics to increase the efficiency of photodetectors, displays and light sources. In addition, the device is suitable for the formation of SERS structures (structures for surface-enhanced Raman spectroscopy) used in the spectral analysis of trace amounts of materials in forensic studies, pharmaceuticals and restoration studies of works of art.

A key advantage of the development is the possibility of simultaneous laser sintering of nanoparticles, which allows the manufacture of monolithic conductive microstructures of interest to microwave electronics. In the case of forming plasmon structures, this technique improves the adhesion of nanoparticles to the substrate surface.^[1]
