  • Patent number: 10807307
    Abstract: The invention relates to the field of additive manufacturing, i.e. the manufacture of three-dimensional physical objects by the successive deposition (layering) of polymer materials, and more particularly relates to 3D jet printing techniques. The present method of printing on a 3D jet printer includes the controlled displacement of a 3D printer printing head, the supply of at least two filaments of a fusible material to the printing head, the heating of the filaments by temperature-controlled heaters, the alternate activation of one of the nozzles by means of a printer control module, and the pressurized supply of a filament to the active nozzle. During switching of the nozzles, the printer control module activates a printing head displacement module, which transfers one of the nozzles into an active position. The movement of a movable platform alters the position of the nozzles relative to a valve for the nozzles, closing off the openings of the inactive nozzles and freeing the opening of the active nozzle.
