What is Laser Marking and How Laser Marking Works?

In the past, marking materials required manual labor, utilizing chisels and hammers to emgrave logos, identification numbers, and other designs. Today, we have modern, efficient, and precise marking methods that eliminate the need for laborious work, such as laser marking. Laser marking involves using laser beams to create long-lasting, permanent marks on a wide variety of materials, such as wood, leather, metals, acrylic, and even diamonds. By selecting the appropriate laser machine for the specific material, high-quality marking can be achieved with ease.

Unlike traditional marking methods, such as CNC routing, drilling, and manual marking, which involve physical contact with the material's surface, laser marking is a non-contact process. This ensures pristine results without damaging or compromising the material's integrity.

Laser beams are generated from a laser source, such as a CO2 tube or a laser diode, and focused on a single point using a convex lens. The resulting spot is typically minuscule, allowing for detailed and precise marking on the material. As the highly concentrated beams make contact with the material's surface, marks are created on the material due to the high temperature of the focused beams. They alter its physical properties, causing a visible change in appearance due to the transfer of energy. These marks have a contrast, which is why they are visible and clear.

The advantages of laser marking are numerous, including ease of use, exceptional speed, and the ability to handle large volumes without hassle. Furthermore, the process only requires uploading the desired design or text to the laser engraver software, and the machine autonomously completes the marking. Laser machines boast incredible accuracy and precision, capturing even the smallest details for exceptional results. Moreover, since the process is contactless, it is safe for both the user and the material, preventing damage or injury.

Due to these benefits, laser marking is an ideal choice for marking a diverse array of materials. It is particularly useful for applying identification marks, QR codes, logos, and other designs to products, and is commonly employed in industries requiring permanent marking.

Precious jewelry items and diamonds can also be laser marked with intricate detail. Additionally, machine parts, automotive components, textiles, ceramics, and various other materials can be efficiently marked using laser machines.

Types of Laser Marking

Laser Engraving

Laser engraving is a widely utilized method of laser marking, commonly employed for inscribing ID numbers, crafting sketches, logos, QR codes, and various other designs. While both laser engraving and laser marking are used to create permanent marks on various materials, they have key differences in terms of the depth, appearance, and applications of the resulting marks.

In the laser engraving process, material is removed from the surface, creating discernible depth and texture. This technique results in a 3D effect when viewed from specific angles, as well as a tactile sensation when touched. During engraving, laser beams elevate the surface temperature to the material's boiling point, causing it to melt and eventually evaporate. In some instances, the material may burn due to the intense heat, transforming into dust or debris.

On the other hand, laser marking, which includes techniques such as annealing and coloration, alters the material's surface properties. This process generally produces a shallower, smooth mark, with a color change or contrast visible on the surface. Laser marking is typically used for creating barcodes, serial numbers, or decorative patterns on materials like metals, plastics, and ceramics.

The engraved markings typically appear darker than the original material color, providing a long-lasting and durable result, thanks to the deep cuts. Laser engraving is particularly well-suited for materials such as wood, plastics, ceramics, and certain metals. When engraving metal, it is important to use a fiber laser with sufficient power to achieve the desired depth and 3D effect. Insufficient power may result in shallow markings, lacking the characteristic depth and texture of a proper engraving.

In contrast, laser marking is more suitable for applications requiring minimal surface disruption or when the material is sensitive to high heat. It is also preferable when a smooth, unaltered surface is desired, as the process does not create any depth or grooves in the material.

2. Laser Annealing

Laser annealing is a technique that uses a laser beam to heat metal slowly. This causes oxygen to diffuse below the surface of the metal and oxidize it from within. When the metal cools down, its color changes. This process is also referred to as heat marking and involves a laser beam applying a small amount of heat to the surface of an object, causing a thermo-chemical reaction . 

While the most common color produced is black, adjustments to the laser's power settings can yield other colors such as red, yellow, and green. Unlike laser engraving, laser annealing does not create cuts or deep marks; instead, the marking is formed on the surface through oxidation, maintaining a smooth appearance. Laser annealing is predominantly employed on metals, particularly titanium, steel, iron, and other ferrous materials. It is widely used in various industries for metal marking, including medical, automotive, and aerospace sectors, due to its non-invasive and precise nature.

3. Laser Foaming

In the laser foaming method, the surface of the material is melted, leading to a phase change that generates gas bubbles. As these bubbles attempt to escape from the surface, they oxidize, creating an eye-catching foaming effect. The foamed bubbles exhibit a visually appealing appearance, characterized by a lighter color, light refraction, and a glittering effect. This combination of properties lends a distinctive and exceptional look to the marked material. Laser foaming is primarily suited for plastics, and it is not compatible with materials such as metals and wood. One notable advantage of this method is that the resulting bubble marks are lighter in color than the original material, making it particularly useful for marking dark plastics.

4. Laser Carbonizing

Carbon migration laser marking is a process that occurs in certain metals and alloys containing carbon. When laser beams are applied to the material, high temperatures cause the carbon molecules to migrate to the surface, where they form bonds with surface molecules, facilitated by the heat. As a result of this bonding, dark marks appear on the surface. This specific laser marking technique is applicable exclusively to metals containing carbon, such as steel, stainless steel, titanium, and numerous other metals and alloys. By leveraging the unique properties of carbon migration, it is possible to create durable, dark markings on these materials.

5. Laser Coloration

Laser beams can generate a range of colors on both metal and non-metal materials, depending on their composition and the laser's speed, power, and other specifications. For example, when laser beams are applied to a metal surface, such as stainless steel, different colors may appear based on the settings used. This phenomenon occurs due to the oxidation of molecules on the metal surface, allowing for the creation of multicolored marks. This technique is also effective for plastics, as the application of laser beams can result in the formation of bubbles. The color of these bubbles is influenced by the laser settings and the specific type of plastic used. Consequently, the desired colored mark can be achieved on the material.

Flat objects can be engraved directly using a laser machine. However, cylindrical and spherical objects require rotary attachments to rotate the object during marking. Ensure that your machine is compatible with these attachments. For example, if you want to mark a baseball, you will need a suitable rotary attachment designed for rotating spheres. Similarly, to mark baseball bats, you will need a compatible attachment for cylindrical objects. Keep in mind that these attachments also have limitations regarding object size, shape, and diameter.

3. Power and Speed Requirement

The maximum optical power that a laser machine can deliver is crucial, as it determines whether the machine can effectively mark the desired material. For instance, low-power diode lasers may struggle to mark metals, but with a power range of 20W to 40W, they can achieve excellent results. For marking wood, low optical power is often sufficient; however, marking metals requires higher power. It's essential to check the machine's optical power before purchasing.

Many people confuse electric power with optical power. There are three types of power associated with a laser machine: machine power, which refers to the electrical consumption of the machine; electrical power of the module, which indicates electrical consumption; and optical power, which indicates the power of the laser beams. Focus on the optical power when considering a machine. 

Optical power values are typically lower compared to the other two types. Some companies may not mention optical power, leading buyers to assume that the machine is more powerful by looking at the electrical power. To avoid misconceptions, always consider optical power when making a decision.
