FIELD: various technological processes.
SUBSTANCE: invention relates to light industry, namely to additive technology, i.e. printing on 3D printer by layer-by-layer application. Disclosed is a version of the printing head assembly, which improves 3D printing technology by layer-by-layer application, increasing the printing speed, the accuracy of feeding the polymer into the printing area, and extending the application, as well as the use of other types of polymers previously not used in 3D printing technology by layer-by-layer application in printing.
EFFECT: possibility of almost instantaneous termination of supply of polymer or disperse system based on it into printing area; possibility of more uniform control of volume of supply of polymer or disperse system based on it into printing area; possibility of printing with liquid solutions (disperse systems) of polymers, monomers and/or oligomers, which are non-Newtonian liquids, exhibiting the Weissenberg effect and having different versions of polymerisation reaction activation.
