    SuperbMelt Metal UV Printing

    1.1, Working Principles of Metal UV Printing

    By relying on the voltage within the printhead, ink from the nozzles is ejected onto the surface of the substrate, achieving the purpose of printing images. Generally, a small printhead contains thousands of nozzles, and the printhead controls the ink ejection amount from each nozzle. The ultraviolet (UV) light emitted by UV lamps reacts with the photosensitive curing agent in UV ink. This causes the pigment molecules in the UV ink to solidify on the material’s surface, achieving rapid drying of the ink. As a result, traditional processes like baking or air drying are not required. UV printers can precisely control the printing patterns on different materials and shapes, primarily relying on the principle of positioning:

    • For X-axis positioning, a grating decoder is mainly used to direct the device’s lateral printing.
      For Y-axis positioning, it relies on the drive of a servo motor to control the length of the printing material.
      For Z-axis positioning, it mainly relies on the lifting function of the print head.
