Laser Etching
Laser etching machines are revolutionary tools that open up amazing possibilities in creating, crafting, and even manufacturing objects with highly intricate and detailed designs. By harnessing the power of laser technology, many industries are transforming a wide variety of materials, ranging from organic products like wood to metals, into breathtaking pieces of art or useful industrial products.
In the following, we will learn about laser etching machines, the materials used, common laser etching applications, and the types of laser etching solutions KEYENCE provides to help improve processes.
What is Laser Etching
Laser etching is a process of using a laser to remove material from a surface. By running the laser beam along the desired path, the workpiece is etched in the desired pattern. The etching depth and type of marking can also be controlled by changing the laser parameters. It can be used for a variety of purposes, including engraving, cutting, and marking. Laser etching is a very precise process, and it can be used to create detailed designs or patterns on a wide range of materials, including glass, wood, metal, and plastic.
Laser etching is becoming increasingly popular for a number of reasons. First, it is a very efficient and cost-effective way to produce high-quality results. In addition, laser-etched designs are highly resistant to wear and tear, making them ideal for products that will be used frequently.

Laser Etching Process
During the laser etching process, the laser beam melts the material, vaporising it or evaporating it. The process is quick and precise, making it ideal for creating high-quality marks on products.
To create a laser-etched product, the first step is to create a design. This can be done using software such as Adobe Illustrator or Photoshop. Once the design is complete, it is saved as a vector file. This file is then imported into the laser etching machine. The machine will read the file and follow the vectors to create the desired shape or design.
The next step is to select the material that will be used for the project. This can be anything from wood to metal to glass. Once the material is selected, it is placed in the machine and secured in place. Then, the machine settings are adjusted according to the type of material being used and the desired results.
Finally, the laser is turned on and directed at the material. The beam will etch the material, following the path of the vector file. As the laser moves over the material, it will gently remove small amounts of material, creating text, images, or patterns on the surface. Laser etching is a quick and easy way to create high-quality products with a unique look.
Laser Etching Applications
Laser etching has continued to play a pivotal role in manufacturing and product design. This process is providing precision and high-contrast markings on many types of materials. This, along with the fact that it enhances product quality, aesthetics, and traceability, makes it an attractive option. The benefits provided, along with the cost-effectiveness, have led to many use cases across a variety of industries.
In the automotive industry, laser etching is necessary, as it is used for marking vehicle identification numbers (VINs) and labeling all types of components. This ensures traceability and quality control, which are essential in this sector where precision and safety are critical.

Similarly, the aerospace industry relies on laser etching to mark specific components, such as turbine blades and connectors. Marks include part numbers and serial information, maintaining rigorous quality standards.
Take a look at the electronics in your household, and you can find products that were laser etched. As an example, most laptops are etched with logos, brand names, serial numbers, and more. This process is invaluable for printed circuit board labeling and marking small electronic components with precision. It is also a popular choice for creating logos, serial numbers, and branding on consumer electronics.

In the medical device industry, laser etching helps with marking surgical instruments, implantable devices, and medical packaging. These etchings provide legible, tamper-resistant information like lot numbers and expiration dates.
Steel instruments
Medicine bottles
As one last example, jewelry and luxury goods designers also benefit from laser etching. They use it for intricate designs and personalised messages on precious materials. For example, a jeweler can laser etch a wedding ring with floral patterns, initials, or even a wedding anniversary date. These etchings add both aesthetic value and authenticity to products.
As you see, laser etching continues to prove itself as an indispensable tool in manufacturing. And as technology and machines advance, more applications will be utilised.

3-Axis Hybrid Laser Marker MD-X Series
The 3-Axis Hybrid Laser Marker MD-X Series combines the strengths of a conventional fibre laser with those of a YVO4 system. Fibre lasers are designed for long service life and high output power, granting high-speed marking and system longevity. YVO4 lasers are designed for high quality, delicate marking, and increased depth of focus for flexibility. Together, these lasers create the MD-X with high peak power and a short pulse laser.
Combining these two laser types creates a system that is powerful enough to meet stringent cycle time requirements but also robust enough to achieve quality markings on any metal. Paired with KEYENCE's 3-Axis control, full field auto-focus, and automatic position adjustment, the MD-X Series is ideal for any metal marking need.
