Abstract: Techniques for printing living tissues and organs are provided. An example apparatus includes a printing platform, bioink printing module with at least one nozzle designed for bioink dosing, a gel-forming composition printing module containing a UV-module, and a nozzle for dosing gel-forming composition that starts polymerizing via UV radiation. A module is provided for relatively displacing the nozzles and/or the platform, in which the bioink printing module is separated from the gel-forming-composition printing module to prevent UV radiation from reaching the bioink printing module. The radiation is directed predominantly parallel to the printing platform to prevent UV radiation from reaching the biological tissues and/or organs being printed.

Abstract: The invention relates to medicine and biology, particularly to the means for artificial manufacturing of biological tissues and organs, and can be used in biotechnology, bioengineering, tissue engineering, regenerative medicine, and in the 3D-printing of biological tissues and organs. Technical character of the invention consists in the development of a method of printing living tissues and organs as well as of the apparatus for its implementation.
