The utility model relates to the field of synthesis technologies, i.e. to the manufacture of three-dimensional physical objects by additive application (layering), particularly involving the use of polymer materials, and more specifically to 3D inkjet printing technologies. A print head of a 3D inkjet printer, containing, disposed in a single housing, a moving platform having provided thereon two nozzles with heaters, and a nozzle switching mechanism, the position of which platform is determined by a moving platform position sensor and is limited by a position limiter. The print head of the 3D inkjet printer is provided with a valve for the nozzles, which valve is capable of bending and provides that one nozzle is closed and the other nozzle is opened during switching between the nozzles, and the nozzles are capable of moving relative to the valve, the valve being stationary. This provides an increase in the quality of the 3D models produced and a decrease in the time taken to produce a single 3D model. |
