Camera based laser marking on the rise

The demand for stable, traceable, and high precision marking processes is increasing in almost all industrial sectors. Whether in medical technology, automotive, e-mobility, or electronics manufacturing, manufacturers are faced with the challenge of implementing markings that are absolutely reproducible despite a wide variety of variants, small marking areas, and high quality requirements.

Trotec Laser is addressing this market development with an image based laser process solution that reduces marking errors, shortens set up times, and integrates quality control directly into the workflow.

More complex components, miniaturised surfaces, and stricter traceability requirements are increasing the pressure on manufacturing processes. Industries with regulatory requirements – such as medical technology or safety critical automotive components – benefit in particular from solutions that execute markings in a clear, documentable, and standard compliant manner. Image based marking processes make it possible to proactively avoid sources of error such as focus deviations, position errors, or thermal drift and to make markings reproducible – regardless of the operator, shift, or component variation.

The approaches of modern image based systems – visual reference, automatic focusing, integrated position control – ensure that markings are placed exactly where they should be.Users can see the exact marking field in the live image before the laser starts, which enables reliable placement and significantly reduces set up times. At the same time, quality characteristics such as legibility, contrast, or code verification can be checked directly in the process. This reduces rework, increases throughput, and ensures stable results across many batches.

Medical technology – UDI marking without compromise

UDI codes on the smallest surfaces must not only be clearly legible, but also documentable. Visual inspection directly at the workplace creates additional security and enables compliance with regulatory requirements.

Automotive and E-mobility – Efficiently managing a wide range of variants

When it comes to connectors, sensors, or battery components, short set up times meet a wide range of variants. Image based processes reduce positioning and focus errors and increase repeat accuracy in series processes.

Electronics manufacturing – Markings in the micrometre range

Miniaturised assemblies require precise micro engraving and verified readability of the smallest DataMatrix or QR codes. Visual alignment and reproducible positioning are essential.
