In manufacturing, that story is written with precision and permanence. From serial numbers to intricate barcodes, part markings ensure every component can be identified, traced, and trusted throughout its lifecycle. But how do you choose the right system to deliver these critical marks?
Have you ever wondered about the small, square barcodes often found on electronic devices, tools, and appliances? While they might resemble QR codes, they’re actually Data Matrix codes, essential components of modern manufacturing processes.
Unlike QR codes, primarily used for consumer-facing applications like websites and social media, Data Matrix codes are designed for efficient data storage and traceability. They’re the only 2D barcodes officially approved by GS1 for regulated healthcare items, emphasizing their reliability and accuracy.
QR codes on the other hand are larger and contain more data, such as website URLs, and can encode information in numeric and alphanumeric form as well as Kanji and other multi-byte character sets.
No matter what industry, when it comes to industrial traceability for manufacturers, choosing the right type of code can leave a production run riddled with misinformation and the chance of getting lost.
Understanding the distinctions between QR codes and Data Matrix codes is crucial for manufacturers looking to optimize their processes. Both codes are two-dimensional (2D) barcodes and consist of a pattern of squares that can be read by a barcode scanner. However, there are notable differences in their shape, size, and data capacity.
What is a QR Code?
QR codes are two-dimensional barcodes scanned by smartphones or other devices with cameras. They store information in a matrix of black-and-white squares, which can be interpreted to reveal data such as URLs, text, or contact information. Think of them as digital links that can be quickly accessed by simply scanning them with your phone.
What is a Data Matrix Code?
Data Matrix codes are another type of two-dimensional barcode, but they are smaller and more compact than QR codes. They are often used in industrial settings, such as manufacturing and logistics, because they are highly durable and can be scanned even when damaged or dirty. Data Matrix codes are useful for tracking individual items or components throughout production, ensuring accuracy and efficiency.
Direct Part Marking
While both QR and Data Matrix codes are in the public domain and can be used royalty free, Data Matrix codes have become the standard for anti-counterfeit measures, part identification, and internal tracking because they feature advanced error-correcting techniques that are more robust than QR codes.
This presents a unique benefit for manufacturers that need to ensure their products can be identified if part of the mark gets damaged or impeded.
Particularly necessary for complex and high stakes industries such as medical, aerospace, and defense, where hundreds to thousands of components are needed in order to assemble a finished product, Data Matrix codes can be read even if up to 50% of the mark gets damaged.
QR codes on the other hand have steadily been adopted in consumer-facing applications. These codes can be found everywhere from business cards to product packaging, containing links to websites, resumes, premium offers, and even restaurant menus.
QR codes have a lower level error-correcting built in, and can be rendered useless with even slight ware and tare. Just 30% of a QR code needs to be damaged before it becomes unreadable.
While these codes are perfect for consumer-forward use, marking a component or part with a QR code presents a real danger for misidentification pending the mark gets damaged.

What commonalities do DVD players, checkout lines at the grocery store, and industrial marking machines all share? Lasers.
But alas, not all lasers are the same.
Do you know what L.A.S.E.R. stands for? Light Amplification by Stimulated Emission of Radiation. In other words, it’s a highly concentrated beam of light. Lasers consist of a:
Gain medium: A material that interacts with electrical currents to stimulate photons of light as they pass through.
Energy supply: Lasers typically receive their energy from electrical currents. These currents are “pumped” through the gain medium, stimulating atoms as light passes through. As the currents are pumped, the light accelerates within the gain medium.
A material to provide optical feedback: The materials selected for optical feedback serve one main purpose: steering the direction of the light beam.
Industrial laser marking systems are used across a wide range of industries and trusted for precision and accuracy to provide marks that are easy to read and stand up to wear and tear over time.
Laser marking machines are capable of marking on a variety of materials, but the material influences the adjustments that need to be made. For example, when the situation calls for laser engraving for metal, the type of metal and the surface preparation influence the quality of the mark and the potential for defects.
Understanding how the laser beam interacts with each type of material and what factors influence the final outcome can go a long way in avoiding defects or issues when industrial laser markers permanently mark products.
Thermal Effect and Marking Quality for Industrial Laser Marking Systems
Heat conduction and diffusion play a crucial role in influencing laser marking technologies and can significantly change the marking quality and efficiency on different materials. Understanding these thermal effects is essential for optimizing the laser marking parameters and achieving desired results.
Metals, especially those with high thermal conductivity (e.g., copper, aluminum), can rapidly dissipate heat away from the laser-material interaction zone, leading to reduced marking efficiency and potential heat-affected zones. Materials with lower thermal conductivity (e.g., plastics, ceramics) tend to localize the heat generated by the laser, resulting in more efficient marking and minimizing heat-affected zones.
When using short laser pulse durations (e.g., nanosecond, picosecond, femtosecond) for marking applications, the heat diffusion during the pulse is minimal, leading to more localized energy deposition and reduced heat-affected zones. With longer pulse durations (e.g., millisecond), heat diffusion becomes more significant, potentially causing larger heat-affected zones and undesirable effects like melting or distortion around the marked area.
Materials with high thermal conductivity (e.g., metals) can rapidly dissipate heat, making it challenging to achieve efficient marking without using higher laser powers or shorter pulse durations. Materials with low thermal diffusivity (e.g., ceramics, some polymers) can better confine the heat to the laser-material interaction zone, improving marking efficiency and reducing heat-affected zones.
For thin materials or substrates, heat dissipation can occur rapidly through the material thickness, potentially affecting marking quality and efficiency. Thicker materials or substrates can better confine the heat, leading to more efficient marking, but also increasing the risk of heat accumulation and potential material degradation. Complex geometries or curvatures can influence heat flow and dissipation, affecting the marking process and requiring adjustments to laser parameters or beam delivery optics.
Another area of consideration is the marking strategies that will be implemented and the potential for heat accumulation. The use of specific scanning patterns (e.g., hatching, spiraling) can influence heat accumulation and dissipation, impacting marking quality and efficiency. Meanwhile, overlapping laser pulses or scans can lead to heat accumulation as well, potentially causing material degradation or undesirable effects.
Another option is the choice to employ pulsing strategies, such as pulse bursts. This approach can help manage heat accumulation and dissipation, improving marking quality and reducing heat-affected zones.
Proper control and management of heat conduction and diffusion can lead to improved marking efficiency, reduced heat-affected zones, and better overall marking quality. In some cases, active cooling techniques (e.g., air or liquid cooling) or auxiliary processes (e.g., pre-heating or post-cooling) may be employed to further manage heat effects and achieve desired marking results on specific materials or applications.
Laser Marking Optimization Tips for Industrial Laser Marking Systems
To optimize laser marking based on the interaction with different materials, several key parameters need to be considered and adjusted. Here’s an outline of the best ways to generate high-quality part marking, focusing on factors such as wavelength, power, pulse duration, and beam quality:
Wavelength selection:
The wavelength of the laser should be chosen based on the material’s absorption characteristics. For metals for example, longer wavelengths can mark products efficiently. Some materials may exhibit better absorption at specific wavelengths due to their chemical composition or color pigments.
Power and pulse duration:
Higher power and shorter pulse durations are generally preferred for efficient material removal or ablation. For metals, higher power and shorter pulses can promote melting, vaporization, and oxidation processes. For non-metals, lower power and longer pulses may be better suited to prevent excessive material degradation or charring. The optimal combination of power and pulse duration depends on the material’s thermal properties and the desired marking quality.
Beam quality and focusing:
A high-quality laser beam with good focus and consistent intensity distribution is crucial for precise and consistent marking. Proper beam focusing can concentrate the laser energy onto a small area, increasing the energy density and improving marking efficiency. Factors like beam divergence, mode quality, and focal spot size should be optimized for the specific material and marking requirements.
Scanning and overlapping:
For larger marking areas or complex patterns, the laser beam may need to be scanned or overlapped across the surface. The scanning speed, overlapping percentage, and scanning strategy (e.g., hatching, spiraling) can affect the marking quality and efficiency. Optimizing these parameters can ensure uniform marking and minimize heat-affected zones or material damage.
Surface preparation:
Proper surface preparation can significantly improve marking quality and contrast. Cleaning and degreasing the surface can enhance laser absorption and reduce contamination. Applying contrast-enhancing coatings or primers can increase marking visibility on certain materials, especially non-metals.
Environmental considerations:
Factors like ambient temperature, humidity, and atmospheric conditions can influence the laser-material interaction and marking results. Controlling these environmental factors or adjusting the laser parameters accordingly can ensure consistent marking performance.
Material testing and characterization:
Conducting material testing and characterization is essential for optimizing laser marking parameters. Techniques like spectroscopy, thermal analysis, and microscopy can provide insights into the material’s optical, thermal, and physical properties. This information can guide the selection of appropriate laser parameters and marking strategies.
Material Interaction and Industrial Laser Marking Machine Settings
Finding the optimal laser marking solution is an iterative process that may require extensive testing and adjustment of multiple parameters. Collaboration between material scientists, laser experts, and application engineers is often necessary to achieve the desired marking quality, efficiency, and durability for specific materials and applications.
Proper selection of laser parameters, such as wavelength, power, pulse duration, and beam characteristics, is crucial for achieving optimal marking results. The laser parameters should be adjusted to match the specific material composition and desired marking quality. Depending on the carbon fiber composite material and the desired marking contrast, surface preparation techniques, such as applying contrast-enhancing coatings or primers, may be necessary to improve marking visibility and durability.

Laser marking, also known as laser engraving or laser etching, is a precise and permanent method of adding marks or designs to various materials. It uses a high-intensity laser beam to alter the surface of the material, resulting in marks that can range from logos and text to intricate patterns.
With both etching and engraving, precision and permanence are key. Whether you’re in the business of personalizing gifts or manufacturing industrial parts, choosing the right laser technology can make all the difference. When considering the two primary methods, laser etching vs. engraving, both provide accuracy but only one can lead to the right final product, depending on your goals.
While laser etching and laser engraving are terms that are used interchangeably, there is a notable difference between the two laser marking processes: the depth of the mark left on the product. When laser etching is used, the mark is typically 0.0001”, while laser engraving 0.0001-0.0005” in depth. Meanwhile, deep engraving is considered any mark deeper than 0.0005”.
Another difference between the two is the process of creating the mark itself. While laser etching uses a beam of focused light, laser engraving uses a rotating lens to direct incoming beams to the surface of the product to create the mark.
Choosing the right method for your needs can depend on other factors than the process itself, including:
Material being marked
Environment
Setup costs
Wear and tear on materials
Speed
Precision
What is Laser Engraving?
Laser engraving is an art form that can be seen in many different materials, from metal to wood and plastic. It is a delicate process that requires extreme precision, as the smallest mistake can ruin a project or result in permanent damage to the material. The technique works by using a high-powered laser beam to vaporize or cut away thin layers of the material being engraved, much like sandblasting, but with more control and accuracy over depth and shape. This allows for high contrast marks to be added with amazing precision, resulting in clean lines and smooth surfaces. Additionally, with the right laser engraving machine and setup, laser engraving can be done quickly without sacrificing detail or accuracy.
This makes the laser engraving process perfect for projects where exact detail is required, such as commercial part marking for medical implants or industrial parts. In these cases, choosing the right laser marking technique can make all the difference; not only will it give you better results but it can also save time and money on production costs.
Pros and Cons of Laser Engraving
Laser engraving offers a lot of advantages over other methods such as sandblasting or chemical etching. One of the greatest advantages is speed; laser engraving can be done much quicker than traditional methods, allowing for high production rates when dealing with large amounts of parts. Additionally, laser engraving provides more control over the depth and shape of the engraved area, allowing for intricate details to be added with amazing precision.
With laser engraving, accuracy and replication are extremely important. The speed of the process is also a great advantage as it allows for quick turnaround times on orders. Laser engraving can be used to add text, logos, or other images to items quickly and with amazing precision. Additionally, because it’s non-contact, there are no worries about wear and tear on the parts like with traditional methods.
However, there are some limitations to keep in mind when using laser engraving. The process is limited to certain materials that can absorb the energy from the laser beam without being damaged. Metals such as aluminum and stainless steel are common choices, but other materials like glass and plastic can also be engraved. Additionally, laser engraving can be expensive to set up since it requires specialized equipment and the cost of laser engraving varies depending on the complexity and size of the job. Large jobs can take longer to complete and require more equipment or materials which can add to the overall price tag.
It’s also important to consider the environment when using laser engraving. The process generates fumes and particles that can be hazardous if proper ventilation is not present. Wearing protective gear, such as safety glasses and gloves when operating the laser in order to protect against eye damage or burns, is also a best practice. Lastly, lasers require constant maintenance and adjustments in order to stay operational. This can add up over time so it’s important to factor that into cost estimates.
What is Laser Etching?
Laser etching is a surface alteration process that uses a laser beam to create an indelible mark on a variety of materials. It’s widely used in industries such as product manufacturing, packaging, and labeling for branding, customization, and personalization. In some cases, it can also be used for decorative purposes like creating intricate designs on wood or other surfaces.
Laser etching works by using intense beams of light to penetrate the surface of the material and create very fine lines or tiny holes. The laser etching process can be controlled with precision allowing for deeper engraving or shallower marking of the material’s surface. This makes laser etching incredibly versatile as it can be used to mark various materials with different depths, whether for promotional purposes or decorative effects.
Pros and Cons of Laser Etching
Laser etching is ideal for making unique designs on surfaces with precision and accuracy. For example, jewelry designers can use laser etching to engrave special messages or patterns on rings, earrings, and other pieces of jewelry.
Laser etching is an incredibly versatile tool in many different industries thanks to its precise marking capabilities and compatibility with different materials. However, laser etching is typically not the best method to use for marking parts in the automotive industry. This is because most parts are made of metal that require a more heavy-duty engraving method such as deep-cut or rotary engraving.
The strength and longevity of these methods make them a better choice for long-term applications, especially in areas where high temperatures can cause regular laser etching to fade easily. Additionally, deep-cut and rotary engravings can create very intricate designs and shapes much more effectively than laser etching can.
Laser Etching vs. Engraving | Next Steps
Choosing the right method for creating marks on your product requires attention to the speed needed, the material being marked, the precision, and other factors. With these criteria in mind, choosing the right etching tools or engraving machines for optimal efficiency is manageable.

We compiled a list of six actionable tips to choose the most suitable laser marking system:
Understand your marking needs
Consider the type of laser technology
Evaluate system performance and speed
Assess software compatibility and ease of use
Consider maintenance and durability
Compare costs and return on investment
1. Understand Your Marking Needs
The use of laser marking systems is not the only choice to be made. Within the laser marking industry, various methods have been proven effective for product marking. The process to use depends on a variety of factors. Three marking methods that utilize lasers include:
Engraving: With laser engraving, marks are made on the surface of an object with high heat that vaporizes the material into dust. This is done quickly and with precision, allowing for unmatched durability and readability, along with better turnaround times on orders that involve a large number of parts.
Annealing: This process changes the color of the metal but does not remove any materials. This is because oxygen is diffused beneath the surface of the metal during a slow heating process. This process is only useful for metals like steel, stainless steel, and titanium.
Etching: In this process, heated surfaces are allowed to expand, creating permanent marks in a faster and more efficient manner. This process provides a contrast that remains readable after post-treatments.
Different marking applications are ideal for different material types. For example, certain metals can be marked using the annealing process (as noted above). Meanwhile, etching or engraving can be useful for metals, plastics, and some other materials – such as wood. However, the process used makes a difference in the marking quality, depth, and the speed at which the marking process is completed.
2. Consider the Type of Laser Technology
Several types of lasers are used in laser marking systems: Fiber lasers use a shorter wavelength than the CO2 laser and are capable of marking non-metallic surfaces. This process is commonly used for plastics and metal, as well as rubber.
CO2 lasers can be used to mark wood, plastic, cardboard, as well as metal. This type of laser uses CO2 gas to create an infrared laser beam. This beam cuts the mark into the material.
UV lasers have an adjustable wavelength and can be used on sensitive materials. This process is also possible to complete cold marking – which protects the product from heat degradation but still provides a readable, long-lasting mark.
3. Evaluate System Performance and Speed
Both marking speed and system performance impact overall productivity. Marking speed can lead to a faster completion rate for a larger order, as noted previously. Meanwhile, system performance can mean consistent production rates over time versus a more chaotic rate of production due to maintenance-related downtime.
4. Assess Software Compatibility and Ease of Use
Laser software is commonly hard to understand and to use because of the settings (except for an expert). User-friendly software offers adjustments that can be completed quickly and with minimal clicks. A secure connection via WiFi means the laser marking system can be utilized anywhere the WiFi reaches across the facility – or outside if necessary.
This allows for marking in real-time and allows for maintenance to be adjusted through the software as well.
5. Consider Maintenance and Durability
While reliable systems might come with a higher initial cost, they often lead to significant savings over time. Reduced downtime, fewer repairs, and longer intervals between major maintenance can drastically lower the total cost of ownership. Also, there are no consumables for laser marking (which is a durability and environment advantage).
Reliability also ties into safety. Systems that are less prone to malfunction reduce the risk of accidents in the workplace, protecting both your employees and your equipment.
Systems designed with ease of maintenance in mind often have modular components that can be easily replaced or serviced. Easy maintenance also means that you can potentially handle many issues in-house without needing to call in expensive external service technicians every time something needs tweaking.
6. Compare Costs and Return on Investment (ROI)
Choosing the right industrial laser marking system is a significant decision that can affect your operation’s efficiency, safety, and bottom line.
When evaluating options, consider not just the purchase price but also the costs associated with maintenance, repairs, and potential downtime. A more expensive system might be more cost-effective in the long run if it’s more reliable and easier to maintain.
These can then be weighed against the potential for increased ROI, which can make the final decision easier to reach. Calculating ROI for laser marking machines takes all of the following into consideration:
Improved efficiency
Productivity rates
Product quality
Laser Marking Systems: Opting for Efficiency
Technology evolves, and so do the needs of your business. A system that is easy to maintain is generally more adaptable to upgrades and changes. This adaptability ensures that your investment remains valuable and relevant, even as new technologies emerge.
A reliable system delivers consistent quality in markings, which is critical for traceability, brand identity, and meeting industry standards. This consistency helps in maintaining product quality throughout the production cycle, reducing the risk of errors or defects. Finding that system means evaluating the above points and determining the most efficient system for your unique production needs.

With current trends in dot peen marking automation, the flexibility and ease of operation only continue to streamline the marking process. Products have reached the market that are portable and not tied to any specific area of the production line. Rather, the use of a secured WiFi connection means the control can be trusted to an operator’s cellphone. In turn, this portable marking machinery can be used in both indoor and outdoor work environments.
The product that requires marking can be of any size and still be within the marking capabilities of the marking system – provided it is made of one of the many materials these systems handle with no issue. These products also come with improved battery life, ensuring an entire day’s work can be completed without requiring a recharge of the unit needed for the marking process.
Considerations for Implementation
For those considering automation for part marking, there are numerous factors to evaluate before incorporating automation. These range from your WiFi connection security level and reliability to the level of training necessary to bring your staff up to speed with this pivot in control in the marking process.

Before you go…
It’s normal to still have questions at this point. If you are still considering your best next steps, our resource on part marking considerations could also be helpful:
Ask anyone inside the industrial manufacturing industry – part-marking is crucial to component traceability when working with large quantities. And while several different types of part-marking exist, Dot Peen marking technology has been a preferred solution for many years.
At a high level,Dot Peen marking machines use either electromagnetic or pneumatic force to rapidly oscillate a stylus, in turn indenting the marks onto the surface of the part.
One of the advantages of Dot Peen is that it’s very flexible and can be used in either manual or fully automated production lines. A lot of the applications Dot Peen serves are manual applications, however, with modular Dot Peen systems, you can start with a portable system and later convert it to an in-line system for integration with fully automated production lines.
The Basics | What is Dot Peen Marking?
If you took apart a Dot Peen machine, one of the most important components you would find is a carbide or diamond-tip stylus.
The Dot peen process is considered a “low-stress” marking method because the mark is generated via material displacement rather than material removal. The carbide stylus strikes the material surface to produce the mark via a series of cold-formed stamped dots. Compared to Laser Marking Systems, Dot Peen does not induce thermal shock to the part surface since the material is cold-stamped rather than super-heated to produce the mark.
Dot Peen systems are commonly used by manufacturers in the aerospace and oil & gas industries where low-stress marking is required, such as tubular and flow control products that are exposed to extreme pressure differential in the oilfield.
Dot Peen marking is viable for material hardness up to 63 HRC. Typically, when a part hardness is greater than 63 HRC, laser marking systems are recommended.
All of Technomark’s Dot Peen machines rely on an electromagnetic solenoid to actuate the marking stylus. Dots are plotted in an X/Y plane via electronic control for precise placement of the Dot pattern. Using electromagnetic force versus pneumatic also provides a greater level of control of both the depth of the mark as well as the ability to mark contoured or complex surface.
Dot Peen Marking: Component Traceability In Action
Dot Peen marking machines are utilized in almost every industrial-goods manufacturing operation, including:
Automotive
Oil and Gas (pipes, fittings valves, other)
Aerospace
Defense
Metalworking (general purpose)
While these machines can run in-line and handle large quantities in an automated production environment, most are operated manually using a battery pack to go mobile.
The best Dot Peen marking machines utilize a fully electric design and that doesn’t require compressed air to operate. All Technomark Dot Peen marking machines feature an Intelligent Driving Impact (IDI) function that allows for marking on many different materials and finishes. The IDI function automatically adjusts and levels the stylus to the workpiece. Whether the part has a curved, wavy, or complex geometry, the stylus will follow the contour of the marking surface while maintaining a constant depth of high-quality marking throughout.
When structural integrity is crucial, Dot Peen marking provides a low-stress marking solution that removes no material during the part marking process.
Why Choose Dot Peen Marking
One of the biggest benefits of a Dot Peen Marking Machine is its ability to efficiently produce marks compared to other marking systems. Other benefits of Dot Peen machines include:

Commerce has come a long way from the bartering system. When currency became the acceptable medium of exchange, it only made sense that a better system of marking products was needed.
The first barcode was created in 1952, but they weren’t put into use in commerce and the transaction process until 1974, when a pack of Wrigley’s gum was scanned in a supermarket in the state of Ohio.
Barcodes have become widely used and have been upgraded and improved in an ongoing process. From the days when a barcode took up a significant amount of the packaging and contained limited information to today’s Data Matrix codes that are significantly smaller and can hold more data, the barcode development process has been fast and focused on efficiency.
Here we will focus on Data Matrix codes, their importance, their history, and an in-depth look at:
How they’re generated
How they differ from other marking processes
What industry these are most common in and on which type of materials and parts are they commonly found
