Abstract
In a focus control system of a printing head for energy deposition processing and a focus control method using same, the focus control system comprises a processing head unit, a laser oscillation unit, a spray unit, an imaging unit, and a stage unit. The laser oscillation unit is mounted on the processing head unit and irradiates a laser. The spray unit is mounted on the processing head unit and includes a nozzle portion for spraying powder. The imaging unit obtains an image of the irradiated laser and an image of the nozzle unit. The stage unit controls the position of the laser oscillation unit on the basis of the image of the laser and the image of the nozzle portion.
