Laser 3D printing is a technology that creates new workpieces by melting elemental or alloy powder. After the laser beam leaves, the alloy liquid quickly solidifies and shapes. The beam quality of the laser can determine the quality of printing, such as fineness, etc. The customized electronic control program allows dual lasers to work on the same object at the same time, shortening the printing time by twice without affecting the printed product at all.
