Logos, serial numbers, or pictures are typically the kind of creations thatcan be done thanks to Laser Engraving. It thus modifies its characteristics, such as its reflectivity, and will create a contrast with its surroundings.Ĭompared to other processes using lasers, such as Laser Cutting or Laser Etching, Laser Engraving keeps the initial shape of the material, and is the most common option to create personalized or customized objects. It is mostly used on metals, and will expand the material by creating a raised cavity. In this particular case, the heat from the beam is not used to vaporize the matter, but to melt it. Laser Etching is a subset of Laser Engraving. The last possibilities are laser engraving machines where the laser and the workpiece are both immobile but galvo mirrors are moving the laser beam on the surface to engrave.ĭifference between Laser Etching and Laser Engraving Other machines dedicated to cylindrical workpieces. There are different types of laser engraving machines :įirst ones are engraver machines where the workpiece stay stable, only the laser moves (or inversely). The depth of the marks is controlled by the number of times the laser beam is passing on the material. This laser engraving machine method is quick, as the material is removed with each pulse of the laser. It is using the laser for marking the surface of an item.
To do so, the laser creates high heat that will vaporize the matter, thus exposing cavities that will form the final image. This process is mostly used to create images on the material, that may be seen at eye level. Laser Engraving (or Laser Etching) is a Subtractive Manufacturing method, that uses a laser beam to change the surface of an object.
