PRODUCT DESCRIPTION

The laser beam is shaped into a ring laser beam, and then the ring laser is focused, and the metal filament passes through the center of the ring laser, and when the metal filament reaches the focal point of the laser, a molten pool of metal is formed. The feeding structure realizes the feeding process in a stable and continuous manner, and together with the relative movement of the processing head and the substrate, the molten pool will be cooled and solidified in accordance with a certain trajectory, and metal parts of a certain shape can be printed.
