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.

Provided are a tissue structure mimetic used for regenerating a tissue and a method for manufacturing the same, and more particularly, a 3-dimensional tissue structure mimetic which consists of a complex of extracellular matrix protein and bone mineral, wherein the complex is specifically bound to a regeneration-functional peptide to thereby be capable of implementing environment of a tissue requiring restoration, and a method for manufacturing the same. In the tissue structure mimetic according to the present invention, bone mineral components are finely dispersed in the extracellular matrix protein to have excellent mechanical strength of the tissue structure mimetic and conductivity which provides a migration path of cells involved in tissue regeneration. Further, environment of the tissue may be implemented by the peptide contained in the tissue structure mimetic to finally remarkably increase tissue regeneration capacity.
