Laser Etching vs Laser Engraving

Before submitting a purchase order, it is best to determine what service your parts may require: Laser Etching or Laser Engraving? It is vital to understand the differences between the two processes to see which is a better marking option for your components. While the two terms sound very similar, there are actually some very key differences.

Frequently Asked Questions

Laser Etching
Laser Etching is the process of using a laser to create extreme heat on the surface of metal. The extreme temperatures cause the selected area of the surface to melt, leaving a small, discolored, and raised bump. Etching is most often used on small-scale electrical components within a larger machine. Components such as metal pens, nameplates, and circuit boards are typically marked through the laser etching process, so as to not reduce their already limited surface area.
Advantages of Laser Etching
When trying to choose whether Laser etching or laser engraving is best for marking your components, it is important to understand the key unique benefits that each offers.

Laser Etching can provide crisp, clean, marking on the surface of your substrate. Some of the most notable benefits of Laser Etching, as opposed to Laser Engraving, are: 
  • High precision
  • Little production time
  • Low Cost 
  • Best marking method for thin and small components
  • And more! 
Laser Engraving
Laser Engraving, unlike laser etching, uses a laser to vaporize material off of the surface of a component. While etching leaves a raised mark, engraving “carves out” it’s marking, leaving it lower than the substrate’s original surface height. Laser engraving is typically used for external aesthetic or marking purposes, like applying a company logo or serial number.
Advantages of Laser Engraving
Laser Engraving can provide a long-lasting, durable, marking, or engraving slightly lower than your substrate’s surface. Some of the most notable advantages of Laser Engraving, as opposed to Laser Etching, are: 
  • Long-lasting mark
  • More resistant to abrasions and other form of wear
  • Faster than traditional engraving 
  • And more!
