The Few Limitations of Laser Marking Technology

Posted by

You may have noticed the hype associated with laser marking technology. After all, laser marking is quite the fad nowadays. However, skepticism towards new technologies is also natural. So, you might be thinking, “Does laser marking technology have any downsides to it?” If you are interested in knowing more, then read further.

An Overview of Laser Marking Technology

Laser marking uses a concentrated beam of light to embed something onto an object. Specifically, a low-powered beam causes oxidation under the material which colors the material black. Only a low-temperature causes discoloration produced by laser marking. Furthermore, it does not cause any damage to the surface of the material. Lastly, laser marking is popular among medical devices for marking stainless steel and titanium, but it is useful for other materials as well.

For users, laser marking is quite efficient. The operation takes a short amount of time, is user-friendly, and it can be as effective or better than manual and tool-assisted devices. Also, compared to other marking devices, the laser marking technology is used for various materials. Ideally, laser markers apply bar codes, logos, QR and UID codes, as well as other types of identification. You can see by now that the laser marking technology is quite versatile.

Nothing is Perfect

As you thought, laser marking technology comes with its weaknesses. After all, nothing is made perfect. Three glaring flaws are its high production cost, requires a safety shielding, and its two-dimensionality.

High Capital Costs

Just like most new technologies, laser marking machines are quite expensive to produce. The machine has a complex overall mechanism. It requires beam expanders and focusing lenses such as F-theta lenses and Galvo mirrors. As you see, these are already costly as individual materials. Overall, the whole mechanism of a laser marking instrument is not a cheap investment, which will lead to a high initial cost when you purchase one.

Shielding Systems Are Required

You might be wondering, “What if someone gets hit by the laser?” Well, that will not happen to anyone at all. Laser marking technologies always require a shielding system to protect its users. The system enhances safety, by ensuring a non-contact process that has considerable standoff distance. Then again, that means requiring more investment for you, so watch out for the high purchasing cost.

Two-Dimensional Plane

Okay, the last issue that goes along with the laser marking technology is the two-dimensional movement. The machine only scans both x and y directions, so it is not that suitable for processing materials with a high hardness or a low ignition point. There is also a lack of humanly feel complained by users because of the two-dimensionality. Hence, some people will prefer more traditional methods than the advanced laser marking technology.

An Objectively Great System

And so, you know about only three minor weaknesses of the laser marking technology by now. Then, you come and think, “Only three? That is relatively few!” You should already admit it, the laser marking tools are amazing. Compared to chemical etching, dot peen, and ink jet technologies, laser marking provides many advantages along with its use. The laser marking’s strengths are its versatile application, excellent and permanent marking quality, fast speed, high flexibility, and the lack of consumables and maintenance, which are unbeatable so far.

Finding A Laser Marking Tool

Are you interested in purchasing a laser marking tool? Well, that is natural as the technology is amazing. Then, look around near your local area. Also, if you want to check online, you can start with Laser Marking Systems & Industrial Printers • Needham Coding as they have quality markers.


Laser marking technology is popular because of its strengths, which are many. While it does come with its few limitations, they do not stop the technology from being objectively excellent.
