What Is The Difference Between Laser Etching And Laser Engraving?

In the manufacturing industry, many terms are used interchangeably without their due consideration of meanings. However, it is important to note that each process refers to a different kind of work procedure and promises different results. Which is why it is important to understand the main differences of commonly used terms. Two of the most commonly interchangeable terms are laser etching and laser engraving, especially in industries that require fast and accurate procedures to create permanent markings in single or bulk orders.

Laser etching and engraving are both forms of laser marking. They are two different marking techniques that bring out different results. The identifying difference between the two procedures is that; laser etching usings concentrated heat and light to raise the workpiece surface, while laser engraving emboss the written material forming a dent or cavity in any working piece.

Laser Etching

This process involves the use of a large amount of energy at multiple intervals via a laser beam to create an impression on any surface. The energy absorbed during the process is converted to heat the metal which results in expanding the workpiece surface at micro level. There are localized changes in the structural format and color of the material. As the surface cools down, it creates a permanent marking. Metals that are commonly used in laser etching are multiple grades of aluminum, stainless steel and zinc. This process also works for plated, anodized and bare metal surfaces. Other non-metallic materials that go well with laser etching are glass, polymer, and ceramic. A laser etching expert can give answers to your relative questions and concerns about the process and desired results.

Some benefits of laser etching include:

  • It is a quick process which provides instant results.
  • It is highly accurate and precise making it ideal for small, intricate details.
  • It is compatible with a variety of materials.
  • It can work well on both thick and thin bases.
  • It is highly cost effective and doesn't take much power

Laser Engraving

Laser engraving refers to making impressions which feel like they have been etched into the working base. It is best suited for marking products that are subject to harsh surface treatments. Metals including stainless steel, brass and titanium are compatible with laser engraving. Non metal materials include fiberglass, wood, and paper.

Some benefits of laser engraving are:

  • They are easily felt and read given the permanent cavity on the workpiece.
  • Laser engraved markings are resistant to common wear and tear
  • It is also a quick and efficient process compared to traditional engraving procedures that require more time and labor making it highly suitable for mass production.

Other Common Differences

  • Laser engraving has deeper cuts than etching which delivers little to no cutting actions.
  • Engraved markings are more durable than laser etched materials which have no indentation.
  • Laser engraving is priced higher than etching due to use of more powerful and sought technology.
