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
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 marking technique 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 equipment 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.

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.

What do DVD players, checkout lines at the grocery store, and industrial marking machines all have in common? Lasers.
But not all lasers are the same.
L.A.S.E.R. stands for Light Amplification by Stimulated Emission of Radiation. In simpler terms, it’s a highly concentrated beam of light. Lasers consist of a:
Gain medium: a material that works in tandem with electrical currents to stimulate the photons of light as it passes through
Energy supply: Energy supply for lasers usually comes in the form of electrical currents. These currents are “pumped” through the grain medium to stimulate the atom as light passes through. The pumping of electrical currents causes the light to bounce faster through the grain medium.
A material to provide optical feedback: The materials chosen for optical feedback have one primary job: steering. the way the beam of light is directed
Laser marking is a versatile process that uses laser technology to create permanent marks on materials such as plastics, metals, and other surfaces. The process works by focusing energy and heat from the laser beam onto a given material, which causes chemical changes in the material’s surface layer. This creates impressions that are highly visible and oftentimes indelible.
A few of the factors that make up this process include: 1. Laser Type: Different types of lasers are used for different types of marking applications. Generally speaking, CO2 lasers can be used for engraving and polymers while fiber lasers are ideal for marking metals.
2. Material: Different materials may require different laser parameters or even completely different types of lasers to achieve desired results. It’s important to consider the material’s properties before selecting a laser type.
3. Quality Requirements: The quality requirements of the applied mark determine which parameters must be considered during laser processing to ensure accuracy and precision. Common laser parameters include:
Pulse rate
Line width
Speed
Power density
Dwell time (the amount of time the laser is applied to a single spot)
4. Equipment Used: Depending on your application needs there are many different kinds of industrial laser marking machines available on the market today – each with their own advantages and disadvantages that should be considered when making selection decisions.
Laser marking offers many advantages over traditional marking methods such as stamping, printing, and engraving. Laser marking is fast, accurate, and permanent. It can also be used to mark a variety of materials without the need for additional setup or alteration. The laser beam never touches the material being marked, making it possible to achieve high-precision marks with no significant post-processing required.

If you’ve ever opened a new electronic device, tool, or home appliance, chances are you’ve seen a Data Matrix code.
While you may have thought it was a QR code, Data Matrix codes are an essential part of most manufacturing processes and act as an efficient means for component traceability. Data Matrix codes are also the only 2D barcode to have GS1 approval for regulated healthcare items.
QR codes on the other hand are larger and contain more data, such as website URLs, and are capable of encoding information not just in numeric and alphanumeric form, but also in 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.
Let’s break down the differences and similarities between QR and Data Matrix codes and why the latter is the preferred choice of the majority of manufacturers.
Direct Part Marking | QR vs Data Matrix Codes
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.
Data Matrix vs QR Codes | Uses Cases and Applications
Data Matrix
Supply chain traceability
Anti-counterfeiting through serialization

Additional product information
Usage instructions
Social sharing
Auto-linking for spare ordering and registration
Promotions, contests, and gamification
Specifications of Data Matrix vs QR Codes
While Data Matrix codes are typically reserved for industrial use cases, both types of marks can play a role in the manufacturing industry.
Since both DataMatrix and QR codes are GS1 approved, they can carry any GS1 ID keys including:
Medical, manufacturing, transport and IT equipment
Loyalty scheme members, doctors at a hospital, library members
Automobile parts
Medical device
Beyond GS1, specifications and requirements for each code are presented by the International Organization for Standardization (ISO). For more about how these codes work themselves, and how to create them, you can check out the relevant ISO standard for more detail.

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 of 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:
Portability: battery-operated systems are ergonomic and perfect for smaller-scale operations or marking of large, heavy parts that cannot be transported to a fixed location for marking
Versatility: state-of-the-art Dot Peen marking systems are modular and can start with a portable or manual marking system that can later be adapted to a fully automated production line
Ease of use: Dot Peen machines are easy to program and do not require any advanced computing knowledge or technical training.
Permanency: Dot Peen marking process yields a permanent, indelible mark that can withstand harsh operating environments
Economical: Compared to other marking systems, Dot Peen systems are typically less than $10,000.
Integrating a dot peen marking machine into your production line will improve the productivity and quality of the part-marking process.
Wireless connectivity between marking head and control (Network-able devices that are able to communicate to other devices through wireless communications)
On-board diagnostic tools to help the operator know when it’s time for scheduled maintenance — protecting your investment.
