Laser technology has become an integral part of modern manufacturing, offering precise, efficient, and dynamic solutions across various industries. Laser marking and laser etching are two widely used techniques in the fabrication sector. While both methods utilise a laser beam to alter the surface of a material, they differ in their execution and general role. To ultimately decide which is the right application for your project, it’s important to understand the key differences and roles in profiling services.
What is Laser Marking?
Laser marking is a non-contact process that alters a surface without extensively removing the material. This process is most commonly utilised on metal sheets and designs when there is a requirement for high-contrast markings and permanent tracking in place, such as QR codes, barcodes, identification and logos. Within the metal fabrication industry, the method of laser marking is popular due to the longevity and readability of the markings, without compromising the materials’ integrity too much.
How Laser Marking Works
The process of marking metals is called ‘annealing’, and it is established by directing a highly-precise and sophisticated pulsated laser beam directly on the surface of the material. This laser generates and uses heat to cause oxidation and discolour the metal’s surface. Laser marking does not melt and vaporise metal but rather alters its appearance, reducing the need for extensive post-processing solutions.
What is Laser Etching?
Laser etching is similar to laser marking in the sense that it can be used for the same purpose when it comes to product tracking and identification. However, the execution is marginally different since etching removes a minimal amount of material in order to create a slightly depressed marking with edges, offering tactile results. Visually, the metal also becomes discoloured, and this method is very common when creating logos, branding designs, personalised products and for traceability purposes.
How Laser Etching Works
A laser etching machine works similarly to laser marking by utilising a high-powered laser beam. In this application, the laser heats the surface of the metal, which causes it to increase rapidly in temperature and expand, therefore leaving a slight indentation. Although results are tangible upon finish, the material removed is very minimal and is typically less than half a mm.
Common Applications of Laser Marking and Etching
Laser marking is commonly utilised to create identification codes, serial numbers, logos and circuit boards. While laser etching can also achieve these results, it can also be used to create permanent aesthetic designs.

The Benefits of Laser Marking and Etching
- High precision and detail created from powerful laser beams for even the most intricate designs.
- Versatile material diversity from delicate metals to robust textiles, there is scope for all project requirements.
- Customisation ability to suit the unique requirements needed for each project.
- Cost-effective due to the rapid nature of the laser process, ensuring labour and turnaround times are exceptionally fast.
- Non-invasive due to the non-contact element of the laser process, ensuring the material does not become compromised.
- Consistency is guaranteed from innovative laser machines that process large batches with remarkable precision and control.
- Utilises CAD software to seamlessly transition from digital designs to the final product.
Laser Marking or Etching: Which Is Right for You?
There are several factors to consider before deciding which laser method is most applicable for your project. In order to develop a deeper understanding, it’s integral to reach out to a professional and knowledgeable laser profiling manufacturer.
Ultimately, deciding between the two will depend on the material of your product, your desired effect, and the intended final outcome. Although both laser techniques are quite subtle compared to the tactile feel of laser engraving, they each serve a purpose depending on the design elements required.
