Abstract
A laser patterning apparatus for a three-dimensional object includes a laser generator, a beam expander configured to adjust a size of a laser beam generated by the laser generator, a dynamic focusing module configured to adjust a z-axis focus position of the laser beam passing through the beam expander, a scan head configured to adjust x- and y-axis focus position of the laser beam passing through the beam expander, a shape recognizer configured to recognize a shape of a three-dimensional object, and a controller configured to extract x-, y-, and z-axis data of the three-dimensional object and to control the scan head and the dynamic focusing module, in order to pattern the three-dimensional object with the laser beam.
