  • Patent number: 11602885
    Abstract: The present invention is a printing device using multiple inks and a printing method using thereof, and more specifically, relates to a three-dimensional printing method of a printed product with a cross-sectional pattern comprising a step of providing different inks into each partitioned spaces and applying the same pressure condition to the inks retained in the ink-receiving part, thereby extruding the inks into a single extruding port to prepare and print an extruded ink product, using the printing device comprising an ink extruding member comprising an ink-receiving part receiving the multiple inks in each partitioned space, and an ink-extruding part equipped with a single passage in which the multiple inks received in the ink-receiving part are passed together.
