As already explained, while marking dissolves the material by modifying its roughness, engraving sublimates the material by creating grooves. To do this, the laser must be powerful enough to vaporize the material in a few milliseconds and the material to be marked must have an adequate sublimation temperature, so deep engraving is not always possible.
When laser engraving occurs, it is important that the laser marker is equipped with a suitable exhaust system. LASIT has designed its exhaust fan, specifically designed to maximize the level of protection of both the environment and the laser itself.
Now that we have a more precise picture of the parameters that lead us to recommend one rather than the other process, it is time to find out about the 10 guidelines for choosing a good laser marker.
