What is a 3D Fiber Laser Marking Machine?

How does a fiber laser marking machine work?

To mark a material, a fiber laser marking machine focuses a beam of light onto the material’s surface and alters its characteristics. This is done through a process called laser cutting. The marking machine has a fiber optic cable containing rare elements such as ytterbium. This cable amplifies light energy, which is later focused on the fiber optic cable. After that, the fiber optic cable directs the light to the marking surface through a controlled galvanometer system. This system marks the laser beam precisely and rapidly.

Like all machines, the marking machine has significant components, including its control software, laser source, scanner head, and marking field lens. The machine functions by ‘activating the laser beam’ to make its temperature exceedingly high. Subsequently, this vaporizer or engraves the material’s surface. Depending on the settings and laser used, different processes can be done to the material, like etching or engraving. For example, during the process of annealing metals, the mark produced on the metal is clear and durable while ensuring that the oxidation state keeps changing.

Research from industry reports suggests that fiber laser technology can reach marking speeds over 7,000mm/s with accuracy levels finer than 0.001mm. This makes them quite useful for elaborate designs and detailed barcodes. Moreover, fiber lasers are forecasted to have lifetimes exceeding 100,000 hours, requiring lower maintenance than other marking technologies. This efficiency and longevity significantly enhance the cost-effectiveness of using fiber laser marking machines in industrial applications.
