FIELD: technological processes.

SUBSTANCE: invention relates to synthesis technologies field, i.e. producing three-dimensional physical objects by additional application (deposition) using polymer materials, particularly, to jet three-dimensional printing technologies. Method of three-dimensional jet printer printing comprises three-dimensional printer printing head controlled movement, supply of, at least, two threads of meltable material into printing head, threads warming up by heaters with controlled temperature, alternating connection of one of nozzles via printer control module and supply of thread under pressure into active nozzle. During nozzles switching printer control module switches on eccentric motor for its rotation. Moving platform is driven into movement around axial screw axis. During movable platform movement one of nozzles is brought into active position by means of driven into inactive position nozzle driven gear disengagement from drive gear and driven into active position nozzle drive gear engagement. At that, movable platform movement displaces nozzles position relative to valve for nozzles, locking inactive nozzles holes and opening active nozzle hole. After movable platform complete fixation in first nozzle activation position printer continues printing with this nozzle.

EFFECT: technical result achieved when using method according to invention consists in improvement of produced three-dimensional models quality with reduction of time for one three-dimensional model making.
