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.

Laser part marking requires an understanding of both the engraver that will best fit your application requirements and the laser source that will provide the best mark. There are a variety of laser sources, and we will highlight three types, as well as two subtypes, of the best laser-marking technology and outline the best choice for the material you are using and the depth of the mark you require to meet regulatory requirements.
5 Laser Sources Based on Wavelength
Laser part marking is common in a number of industries because it is effective for long-term part identification and meets the rigorous standards set forth for aerospace, mechanical, and other high-demand industries.
However, each industry has specific needs when it comes to the product, and the potential damage to the product if the wrong laser is used. The equipment you need is part of the process, but from there the laser that is best is the next point to consider.
With that in mind, we can take a look at five of the commonly used lasers and the best use case for each:
CO2 laser
Fiber laser
YAG laser
Green laser
UV laser
1. CO2 Laser
CO2 laser marking is a popular laser engraving and marking solution because of its ability to mark non-metallic materials. It’s efficient in marking a variety of non-metals, too, including:
wood
plastic
glass
textiles
cardboard
The CO2 laser produces an infrared laser beam and uses CO2 gas as the active medium. The laser is emitted at 10.6 micrometers and features high beam quality, allowing it to focus laser power into a small spot and produce high-quality laser marks. This laser has the longest wavelength, which is located on the invisible infrared spectrum.
This laser is efficient for cutting some materials and for personalizing products. However, this type of laser also requires more maintenance and uses more energy.
2. Fiber Laser
Another laser source is fiber laser marking, which also offers the ability to mark non-metallic surfaces with a high degree of accuracy. This laser source utilizes a shorter wavelength than a CO2 laser and uses a fiber optic laser device to emit laser beams at a wavelength of 1.064 micrometers. The wavelength produced is located in the infrared spectrum.
It quickly and accurately produces laser marks on materials such as:
plastics
metals
rubber
glass
This laser source also offers the ability to be tuned for specific applications with easily adjustable settings.
A fiber laser can also be used for embossing or to add discoloration where desired. The discoloration process with a fiber laser provides avariety of colors and better control simultaneously.
The fiber laser is the most commonly used in the laser marking industry, particularly common in aerospace, metallurgy, automotive, and mechanical applications. It’s useful for all types of metals and has a long lifespan when compared to other lasers.
3. YAG Laser
The YAG laser operates on a wavelength similar to the fiber laser (1.064 micrometers). However, this type of laser has a different structure than a fiber laser and the beam passes through different crystals in order to create the beam.
The YAG laser is ideal for marking metals and plastics in its more widely recognized configuration. However, it can be adjusted to mark more sensitive materials as well.
4. Green Laser
The green laser, the first subtype of the YAG laser, is the only laser with a wavelength in the visible spectrum. This allows manufacturers to mark many sensitive materials, such as:
polymers
plastics
rubber
The green laser is ideal for these sensitive materials because its wavelength is located near the UV spectrum generates less heat.
5. UV Laser
The UV laser is another subtype of the YAG laser. Thanks to implanted crystals, it became possible to adjust the wavelength for this laser and utilize others, providing access to the only laser in the invisible ultraviolet spectrum (0.355 micrometers).
The UV laser has the shortest wavelength used in the laser marking field and as such is relied upon for markings on fairly sensitive materials.
This laser also makes it possible to carry out “cold markings” — which means manufacturers can avoid the degradation of parts due to the heat. This laser is used for marking solar panels, electrical components, and other parts that require a refined approach.
6 Ways to Choose a Laser Marking Source
Planning production of your next line means a lot of considerations. These include the material you will use and the speed you can expect products to be completed. Meanwhile, several of those factors also influence the choice of laser:
Material to be marked
Mean time between failures (MTBF)
Depth of mark needed
Laser maintenance needs
Speed of marking process
Ease of settings adjustment
1. Material to be Marked
With the variety of materials used in production, it makes sense to prioritize the materials when considering a laser source. For more heat-sensitive materials, it’s important to find the right laser and access one that is easily adjustable.
2. Mean Time Between Failures (MTBF):
The Mean Time Between Failures (MTBF) is a guideline of how reliable your laser will be based on its hours of operation. Each laser has a different expectation — and keep in mind these are mean times, not a guaranteed lifespan. Some lasers have a longer MTBF but can fail in a shorter period of time than expected
While the fiber laser has an MTBF of 100,000 hours, CO2 lasers have a significantly shorter MTBF of 30,000 hours. This is a crucial factor to keep in mind while choosing the best option for your production cadence.
3. Depth of Mark Needed
Some lasers are singled out for the ability to make deeper marks than others. For certain regulations and standards, the laser with a deeper marking capability would be the preferred choice.
Meanwhile, other materials require a lighter mark that doesn’t cause damage. Therefore, the depth of the mark is a key factor in laser source choice.
4. Laser Maintenance Needs
Some lasers require more maintenance than others. This means a commitment of more of the budget and possible interference with production timelines if maintenance is required frequently.
5. Speed of Marking Process
Your production timeline is important both for your revenue and to help your clients meet their own projected deadlines. As such, the marking process needs to be completed in a timely manner.
Note: Depending on the material to be marked, the right laser source makes a difference in meeting that timeline and getting behind due to lengthy marking processes. If laser marking isn’t the answer at all, there’s always dot peen marking.
6. Ease of Settings Adjustment
In some industries, the laser will need to be adjusted for separate part lines or stages in the production process. In these cases, it is more cost-effective to find a laser that can be adjusted easily. This better facilitates effective marking on the desired timeline.
Which Laser Marking Source is Right for Your Production Needs?
With three laser marking types and two subtypes, it should be a reasonable process to narrow down the best laser for an application based on the factors involved. Your production line requires a certain type of mark and you have an expectation of how long that mark will last.
The right laser marking source means faster delivery of products that carry distinct markings to fit your clients’ needs.

Laser marking systems provide reliability and long-term marking solutions for commercial and industrial applications, which resolves concerns about component tracking for many industries where the product is exposed to extreme heat or other conditions that cause wear and tear.
Choosing the best laser marking system for your production line means weighing the various factors that determine the most effective yet least time-consuming process to meet deadlines.
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.

Laser marking and dot peen marking are both widely used in industrial applications for the permanent marking of parts and products, but they differ significantly in their mechanisms and outcomes.
Laser marking utilizes a high-intensity light beam to etch or mark the surface of a material, allowing for precise, high-resolution marks including barcodes, QR codes, and intricate graphics, while dot peen marking involves a pneumatically or electromechanically driven pin that physically impacts the surface to create dots forming numbers, letters, or simple logos. Both are useful in any number of industries – depending the needs and expectations of the product line in question.
Investigate the Options, Starting with the Laser Marking System
Our Part Marking page offers a detailed look at the types of lasers and benefits of each, as well as the benefits of dot peen marking as an alternative. The guide also shares info on the type of mark needed and the materials you are marking during production. Take a look:
Direct Part Marking (DPM) is a process utilized by various manufacturers to improve the traceability for the parts they create, and also to cut down on data entry errors and issues related to safety, warranty, and liability.
For defense and military applications, part marking specifications streamline the process of identifying parts throughout the manufacturing process; and in the event of any potential safety or liability issues, using 2D codes etched/imprinted directly on the part to expedite the process. DPM also facilitates the satisfaction of regulatory requirements related to identifying stolen parts and makes it easier to identify counterfeit parts.
Manufacturing for the defense and military industry requires
accuracy
permanency of the identifier’s application
readability of the code at any point in the component’s life cycle
guarantee of unique IDs marked for each part.
The simple operation, with effective maintenance procedures, is also key in meeting the required standards for defense and military products.
Direct Part Marking for Defense and Military Applications
Nearly every component in military vehicles, tanks, and fighter jets requires DPM for effective marking of all components involved.
To manufacture these modes of transport for soldiers who may be in combat situations, the most accurate and traceable manufacturing processes must be utilized.
Other areas where DPM is crucial include both ammunition and firearm production. Laser Marking has been recently added to dot peen marking, chemical etching, and other metal marking processes as an acceptable method of DPM for defense applications.
Laser marking is more cost-effective, reduces waste, and increases speed and accuracy in the part marking process.
Item Unique Identification (IUID) is a process implemented globally to distinguish items – particularly those purchased by the Department of Defense. The management process provides the DoD access to the part’s location, and value wherever it is located and at any time during the product’s life cycle. This program is known as Serialized Item Management (SIM).
The IUID Army designation allows the military branch to specify products needed by that branch. To facilitate this process, a DPM Code is issued for each product manufactured, and that unique code can be read via special DPM Laser scanners created for the task.
Dot peen marking is another type of direct part marking used in various applications, including for defense. The machines use a fully electric method of marking and do not require compressed air for effective operation. Dot peen marking allows marking on a variety of materials and finishes but does not remove material from the product.
MIL-STD-130 Explained
Military Standard 130, or MIL-STD-130, is the standard set for all tags and labels for products sold to the Department of Defense. This particular standard outlines the durability requirements for the barcode. The barcode is required to be readable following equipment-appropriate cleaning processes, exposure to specific environments (ex. High heat exposure), and earn at least a ‘B’ grade after a prescribed verification process.
Also, a label with human-readable text is required, in the event, the barcode is damaged or obscured at any time. Capitalized letters are required, specific fonts are approved for use during the DPM process, and the size and numbers used are also carefully outlined by MIL-STD-130.
Laser marking, dot peen marking, laser engraving, acid etching, and metal stamping are some of the approved processes that fulfill part marking specifications for products that will be sold to the US Military.
Final Thoughts on Part Marking Specifications for Military and Defense
DPM ensures reliable identification throughout the manufacturing process and the part lifespan for parts used in many manufacturing spheres, including military and defense.
The process prints 2D codes directly onto the part and cuts down on data entry errors and issues with part identification in situations related to safety, warranty, or liability issues.

Effective part-marking is indispensable for ensuring seamless component traceability in the industrial manufacturing sector, particularly when dealing with large quantities. Among the various part-marking options available, Dot Peen marking technology has stood out as a preferred solution over the years.
Dot Peen marking machines use electromagnetic or pneumatic force to rapidly oscillate a stylus, creating indents on the part’s surface. Notably versatile, Dot Peen technology adapts well to both manual and fully automated production lines. While commonly employed in manual applications, the flexibility of modular Dot Peen systems allows for an initial portable setup, which can later be seamlessly transformed into an in-line system for integration with fully automated production lines.
The Need for Automation
While dot peen marking is a well-established method of ensuring traceability, it comes with challenges. These include the need for an in-depth understanding of the process, the right direction for the machine, and using the wrong methods for the material the product is made of.
Today’s industries prioritize timelines and the reliable delivery of products. With that in mind, there is an increase in the need for efficiency to ensure deadlines are met. Incorporating automation into production lines, particularly for part marking, has led to significant progress in addressing and resolving efficiency issues.
Technical Aspects of Automated Dot Peen Marking
As marking systems continue to evolve, the benefits of utilizing these systems can’t be ignored. These systems offer avoidance of downtime via their capability to:

Dot Peen marking systems can be integrated with any system. Portable, in-line, and bench models provide the options needed to maximize the efficiency of your traceability system. Automated options mean better versatility for your dot peen marking and reduced need for human oversight of that aspect of production.
Software Capabilities for Automation
Software has advanced to allow for control of the automation process from outside the facility if you so choose. Meanwhile, the control and adjustment via software means better control and improved marking accuracy.
Customization Options for Specific Industrial Needs
Permanent part marking means reliable part marking for product identification purposes throughout the product’s life span. Both dot peen marking machines and laser marking options offer the versatility to mark a product with a serial number, Datamatrix, logo, or other pattern as required. This then can be used to track the product through its production and installation – and beyond.
For more precise orientation and focus, the laser technology may be helpful. Meanwhile, dot peen marking is a long-trusted method of part marking that provides a mark that impacts the surface via a succession of dots. This method is hard to wear away or otherwise deteriorate, leaving it easy to read for long periods.
From automotive parts and aerospace applications to the oil and gas industry, many industries utilize these marking systems to increase traceability and reliability in part identification into the future.
Trends and Innovations
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.
Consider these resources to evaluate your readiness for automation in your marking system:

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.

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 wins in precision and detail, making it preferable for industries requiring intricate designs or small text. It is considered ideal for barcodes, UID codes, QR codes, and detailed logos.
