What is one method to enhance the depth of laser engraving?

Using multiple passes is an effective method to enhance the depth of laser engraving. When the laser engraver makes several passes over the same area, it allows for more material to be removed with each pass. This cumulative effect results in a deeper engraving as the laser continues to interact with the substrate, removing more material incrementally.

This method is particularly useful for materials that may not respond well to a single pass at high power, which could lead to issues such as excessive burning or material splatter. By adjusting the number of passes, you can achieve the desired depth while maintaining the quality and appearance of the engraving.
