Metal Engraving Methods: Difference Explained

In the realm of metal engraving, there are three primary methods to choose from: laser engraving, laser etching, and laser marking. Beginners usually get confused because these words are used interchangeably. Each technique has its advantages and limitations, making it essential to understand their differences before selecting the most suitable method for your specific application.

Laser Engraving Metal

Laser engraving involves using a high-power laser beam to increase the metal surface's temperature beyond its boiling point, causing the material to change from a solid state directly to a gas through a process called sublimation. As the surface material evaporates, it leaves a cavity, creating a deep, visible engraving with a 3D surface that can be seen and felt. This method provides excellent precision and accuracy, making it ideal for intricate designs, small text, and detailed graphics. Laser engraving is widely used for various applications, such as personalizing jewelry, creating custom awards, and marking industrial components. 

However, metals have high boiling points due to their tightly packed molecules, with melting temperatures often exceeding 1000ºC and boiling points surpassing 4000ºC. To laser engrave metal, a powerful laser engraving machine specifically designed for this purpose is required. These machines utilize high-energy pulses to rapidly increase the metal's temperature. Low-energy, hobbyist, or DIY laser engravers cannot directly engrave metal, but they can be used for metal etching.


  • High precision and accuracy
  • Permanent and durable marks
  • Suitable for intricate designs and small text


  • May require a coating or pre-treatment for certain metals

Laser Etching Metal

Laser etching differs from laser engraving as it does not vaporize the metal. Instead, it melts the upper microsurface of the material, causing oxidation and a change in the original color. Laser etching metal can be done with laser engravers of lower power level at 5w~15w. 


  • Faster process compared to laser engraving
  • Can be done with less powerful laser engravers
  • Suitable for creating high-contrast marks


  • Less durable than laser engraving
  • Marks may fade over time

Laser Marking Metal

Laser marking is similar to laser engraving in that it creates permanent marks on the metal's surface. However, some experts differentiate between laser marking and laser engraving based on penetration depth. In laser marking, the penetration is not as deep as in laser engraving.


  • Creates permanent marks
  • Suitable for various applications like logos, ID numbers, and QR codes


  • Penetration is not as deep as laser engraving
  • Not as suitable for creating depth or texture

The Versatility of Metal Laser Engraving

We have explored the concept of metal laser engraving, which involves removing particles from a metal surface through the use of high-energy pulsed lasers. These powerful laser pulses are capable of rapidly increasing the metal's temperature to its boiling point, causing the material to evaporate and leave behind a permanent cavity known as an engraving.

A metal laser engraver that can produce such high-energy pulsed laser is the most versatile and efficient method for metal engraving. In contrast, continuous-wave laser engravers do not have the peak power necessary for this purpose. Laser etching, on the other hand, relies on continuous-wave lasers to provide just enough energy to oxidize the metal surface. The laser beams are absorbed by the metal, increasing the surface temperature and creating an oxide layer in the presence of oxygen. This oxide layer has a different color, resulting in a distinguishable mark on the surface.

One of the key advantages of laser etching metal is the ability to achieve multiple colors on the metal surface. The color outcome depends on both the metal type and the applied laser beam wattage. By adjusting the wattage, various colors can be obtained, making laser etching an attractive option for decorative purposes.
