Webinar follow-up with Merck: How to improve laser marking through functional pigments

Silvia Rosenberger, Technical Marketing Manager at Merck KGaA, Darmstadt Germany, held a lecture as part of the FOBA “Virtual Manufacturing Day 2020” webinar series on January 14, 2021. As an expert for laser pigments, she explained together with her colleague Stefan Gutberlet, Global Marketing Manager Industrial Pigments, how plastics can be optimized for obtaining best laser marking results.

During the webinar, which attracted many participants, numerous questions came up which could not all be answered due to limitations of time. Therefore, as a webinar follow-up, Silvia Rosenberger and Stefan Gutberlet kindly provide their missing answers for the FOBA blog.

The webinar recording “Lasermarking of polymers and the improvement through laser pigments” from January 14, 2021, is available on demand at

 Just in a nutshell: What is the benefit of using laser pigments?

Stefan Gutberlet: Customers either ask for an improvement in speed or in marking quality. So, we say: Once the lasers become faster, the material must keep up with it. And this is what our pigments do. They improve the marking speed, the contrast and the line definition with pulsed DPSS or fibre lasers in polymers. Without laser pigments most polymers do not contrast mark at all.

Differences between Marking Time and Cycle Time for Direct Part Marking with Laser

There is a difference between marking time and cycle time for industrial parts marking. “Okay”, you might say. “So what? Does that matter?” The answer is simple: Yes, it does. At least, if a realistic throughput calculation matters to you. For example, in order to validate if you can meet the target output with your equipment, stay within the calculated costs per part, and plan your internal resources such as required production people correctly.

What is a MOPA Laser and What is it Used For?

Fiber laser markers, be it pulsed or continuous wave, have prevailed in nearly all industries for marking products permanently and in high quality. The fiber lasers that are used for industrial part marking usually are either Q-switch or MOPA lasers. As of today, Q-switch lasers are more common because they have already existed on the market for a longer time. That is why they are sometimes called “standard laser”. But due to their high flexibility, MOPA lasers like the FOBA Y.0201 and Y.0201-DN, are an interesting alternative for many applications.
