Metal
This is where the Fiber laser excels. Metal products can be engraved with a fiber, instead of just etching the surface. There are still some cases that benefit from a etching, instead of deep engraving, such as photographs. Challenge coins are a great way to commemorate a special event. Kitchenware is another good medium. Give the chef of the house a nice personalised knife they can cherish. Wedding, and Christening gifts, with dates, and times are a lasting memory.
