Laser engraving machines for engraving metal – fiber lasers

When engraving metal, a fiber laser is generally used because of its ability to create accurate and deep engravings. A fiber laser uses an optical fiber as the laser medium, which allows for more efficient generation and concentration of light. This results in a powerful laser beam that is suitable for engraving various metal materials.

There are two main types of fiber lasers used for metal engraving: the ordinary fiber laser and the MOPA fiber laser.

Ordinary Fiber Laser

A regular fiber laser produces a continuous laser beam, also known as a CW (Continuous Wave) laser. These lasers operate on a single wavelength and have a high peak power, resulting in excellent engraving quality and speed. They are ideal for engraving metals such as steel, stainless steel, aluminum, copper and brass. Ordinary fiber lasers offer good overall performance and reliability for metal engraving.

MOPA Fiber laser

MOPA stands for Master Oscillator Power Amplifier. A MOPA fiber laser is an advanced variant of the regular fiber laser. The main difference is that a MOPA laser has the ability to precisely adjust the pulse durations and frequency of the laser beam. This means that a MOPA laser has more control over pulse energy and pulse duration, which is advantageous when engraving certain metals.

Advantage of MOPA fiber lasers

In summary, while a regular fiber laser provides excellent performance for general metal engraving, a MOPA fiber laser offers more flexibility and precision in engraving specific metals and controlling the engraving color. The choice between the two depends on the specific requirements of your application and the type of metal you want to engrave.

The advantage of a MOPA fiber laser is that it offers more flexibility in engraving different metals, especially materials with a sensitive surface coloration, such as anodized aluminum or stainless steel. By changing the pulse durations, a MOPA laser can better control the heat effect on the metal and thus have more control over the engraving color and the amount of surface change.

Important factors when choosing a laser engraving machine metal

Power Levels: Metal engraving generally requires a laser engraving machine with a higher power level to cut through the hard surface. Make sure the machine you choose has enough power to achieve the desired metal thicknesses and engraving depths.
Laser source: Fiber lasers are commonly used for metal engraving due to their high energy efficiency and ability to provide accurate results. Verify that the laser engraving machine you are considering has a reliable and powerful fiber laser source.
Engraving Area: Pay attention to the size of the engraving area, as this can affect the size of the metal objects you can engrave. Choose a machine with an engraving table large enough to meet your needs.
Software and ease of use: An intuitive and easy-to-use software interface is essential to make engraving on metal easier. Make sure that the laser engraving machine comes with software that allows you to easily create designs, adjust parameters and manage engraving settings.
Cooling system (if applicable): Laser engraving machines generate heat during the engraving process, so an efficient cooling system is important for the machine to function optimally. Make sure the machine is equipped with a reliable cooling system to extend the life of the laser source and maintain the quality of the engraving results.
Air filtration: When laser engraving metals, the metal is vaporized and ends up in the air as very small particles. This is very harmful when these laser vapors are inhaled. Always make sure that your fiber laser is supplied with good air filtration to keep you, your operator or other persons who are regularly in the vicinity of the fiber laser.

Advantages of a laser engraving machine to engrave metal

High precision: Laser engravers offer unparalleled precision when engraving on metal. You can achieve fine details, thin lines and complex patterns with pinpoint accuracy.
Sustainability: With the right settings and parameters, laser engravings on metal can be very durable and resistant to wear, corrosion and fading.
Fast and efficient engravings: Laser engravers can quickly create engravings on metal, allowing you to work efficiently and increase productivity.
Versatility: In addition to engraving text and images, you can also apply markings, serial numbers and barcodes with a laser engraving machine for metal.
No contact engraving: The laser engraving technology enables contactless engraving, so there is no physical contact between the tool and the metal surface, reducing the risk of damage.
Minimal material waste: Lasers engrave very precisely, so there is minimal material waste. This makes it cost efficient and environmentally friendly.

Maintenance and safety

When choosing a laser engraving machine for metal, it is also important to take maintenance and safety aspects into account. Make sure you are familiar with the maintenance procedures and requirements of the machine, as well as the safety precautions to be taken when using it. For optimum performance and safety, refer to the manual and follow the manufacturer's instructions.

Applications of laser engraving machines to engrave metal

Here is a brief summary of some applications of laser engraving machines for metal:

Personalization: Laser engraving machines for metal are widely used for personalizing metal objects, such as jewelry, gifts, trophies and name tags. Engraving initials, names, special messages or designs adds a personal touch to the metal object.
Industrial marking: Laser engraving on metal parts is used for industrial markings such as serial numbers, barcodes, QR codes and product identification. This facilitates traceability, inventory management and quality control in various industries.
Art and decoration: Laser engraving on metal offers artists and designers the opportunity to create unique and detailed works of art. From abstract designs to realistic images, laser engraving adds an artistic element to metal panels, wall decorations, sculptures and other decorative objects.
Industrial manufacturing: Laser engraving machines for metal are widely used in industrial manufacturing for marking products, parts and tools. By making precise engravings on metal surfaces, manufacturers can apply their brand name, logo or technical information in a durable and professional way.
Electronics and printed circuit boards: Laser engraving is also used in the electronics industry for marking components, printed circuit boards and housings. This makes identification, tracking and assembly easier and more efficient.
Medical applications: In the medical sector, laser engraving machines are used for marking medical instruments, implants and prostheses. This ensures traceability and identification of medical devices during use and sterilization processes.

These applications are just a few examples of what is possible with metal laser engraving machines. The versatility, precision and durability of laser engraving make them suitable for a variety of industries and creative projects.
