1. A stack visualization method using a stack visualization apparatus including a CNC machine, wherein the CNC machine contains a deposition head, the method comprising:
determining, by a processor, a moving speed of the deposition head, position information of the deposition head, and position information of the CNC machine in real time;
determining, by the processor, laser power information of the deposition head by which a laser is irradiated to a stack in real time;
selecting, by the processor, a virtual stack corresponding to the determined moving speed of the deposition head and the determined laser power information among a plurality of previously stored virtual stacks based on the determined moving speed of the deposition head and the determined laser power information; and
detecting and displaying the selected virtual stack through a digital twin model via a display device in real time,
wherein, during the displaying the selected virtual stack, the CNC machine and the deposition head are further displayed through the digital twin model via the display device in real time, based on the position information of the deposition head, and the position information of the CNC machine.
