According to the present invention, a 3D printing method using a Lissajous pattern and a Lissajous pattern using a Lissajous pattern in which two laser beam axes are simultaneously operated at a high speed by using a Lissajous pattern and a 3D printing process of outputting an accurate output at high speed. It is about. To this end, the present invention is the object size measuring step of measuring the size of the object to be laminated, the minimum diameter calculation step of calculating the minimum diameter of the laser beam required for curing the laminated material, and the laser beam and the scan mirror A synchronization step of synchronizing, a processing path setting step of setting a processing path of the laser beam using a Lissajous pattern, and a lamination material curing step of curing the laminated material by the laser beam based on the processing path; In the curing of the laminated material, the laser beam is irradiated at a point where the object is formed in the processing path, thereby providing a 3D printing method using a Lissajous pattern.
