HEAD STRUCTURE OF 3-DIMENSIONAL PRINT FOR MIX AND REALIZATION OF COLOR, AND METHOD FOR MIX AND REALIZE OF COLOR USING THE SAME

The present invention relates to a head structure in 3D printer for mixing colors and embodiment thereof and a method for mixing colors and embodiment thereof using the 3D printer head. In a first aspect of the present invention, the head structure comprises: a nozzle (20) which is an inlet for printing materials; an inserting element (40) for the printing materials; and a body of the head (10) which is mounted on the nozzle (20) and melts and stirs the printing materials. In addition, the present invention ensures to print the colored printouts depending on the characteristics thereof by mixing various colors according to a combination of each different ABS filament-type printing material inserted through the inserting hole for the printing materials. A second aspect of the present invention comprises: a first step of which ABS filaments (31, 32, 33) are simultaneously inserted into a melting room (12) through the inserting hole in the inserting element (40) for the printing materials; a second step of which the solid ABS filaments (31, 32, 33) which are inserted to the melting room (12) melts into the liquid filaments as a heating coil (11) is heated; a third step of which the molten filaments are inserted into a mixing room (13); a fourth step of which a mixing process is implemented on the pigments which are turned into a liquid mixture by a mixing motor (15); a fifth step of which a printing process is completed as the liquid filaments are sprayed outside through the nozzle (20).
