1. A deposition data collection apparatus comprising:
a printing unit including:
an extruder for ejecting a material supplied from an external material source; and
a printer head for moving the extruder in a predetermined direction such that the material ejected from the extruder are sequentially deposited on an XYZ coordinate system to form a target three-dimensional object; and
a scanning unit including:
a sensing module for sensing movement of at least one of the extruder and the printer head; and
a data collection module for chronologically collecting material deposition data, based on the movement sensed by the sensing module,
wherein the extruder is coupled to the printer head so as to move along the printer head,
wherein the printing unit further includes:
a printer base installed to be spaced apart from the printer head in a Z-axis direction on the XYZ coordinate system; and
at least one hinge pin for hinge-coupling the printer head and the printer base to each other such that the printer head is moveable in at least one of an X-axis direction and a Y-axis direction on the XYZ coordinate system,
wherein the sensing module includes an X-Y axial sensor for sensing at least one of:
a first inclination angle indicating an angle at which each of the at least one hinge pin is inclined from the Z-axis direction toward the X-axis direction on the XYZ coordinate system; and
a second inclination angle indicating an angle at which each of the at least one hinge pin is inclined from the Z-axis direction toward the Y-axis direction on the XYZ coordinate system, and
wherein the data collection module calculates a movement coordinate of the extruder in at least one of the X-axis direction and the Y-axis direction based on at least one of the first inclination angle and the second inclination angle sensed by the X-Y axial sensor.
