Trade Fair Laser: New Trumpf ultra-short pulse marking lasers

With the TruMicro Mark 1020, which Trumpf will present at the Laser World of Photonics 2023 trade show in Munich (June 27-30), medical technology manufacturers can mark their products three-dimensionally with very short pulses without the material heating up much. Even on complex, three-dimensional surfaces, a so-called micro-nano-structuring is created that becomes visible because it captures the light. As a result, the marking appears deep black from all angles and is easy to read. Experts therefore refer to this as blackmarking. This application is particularly important for medical technology manufacturers. Their products are traceable thanks to the marking and can be reused for a particularly long time at the same time. Thanks to the laser's small focus diameter of less than 50 micrometers, users can also mark very small components precisely. "This is a major advantage, for example when marking stents," says Breitenborn. These implants, only a few millimeters in size, keep blood and nerve pathways open. In this way, doctors can get a better grip on lifestyle diseases such as heart attacks and strokes. In the U.S. alone, patients receive more than two million stents a year, and the trend is rising.

The aerospace industry also relies on "cold" marking. This industry has strict requirements for the so-called structural modification of materials: The marking process must not impair the structure and strength of the components under any circumstances. Otherwise, in the worst case, components of aircraft or rockets could break. "Only the TruMicro Mark 1020 ultrashort pulse laser enables this "cold" 3D black marking process on complex 3D surfaces made of metal," says Breitenborn. Users can not only mark with the TruMicro Mark 1020, but also cut, drill or structure materials such as metal, glass, ceramics or plastics. This is made possible by the laser's very high peak pulse powers. Important for quality assurance: The permanent measurement and documentation of the laser power ensures marking and processing quality that can be tracked at any time. Large companies can easily integrate the TruMicro Mark 1020 into their line production. This is made possible by the laser's modular design and compact dimensions. Since the TruMicro Mark 1020 has all common industrial interfaces, it is suitable for use in networked manufacturing. Users can expand the TruMicro Mark 1020 into a complete solution, for example with the TruMark Station. However, the system is also ideally suited for smaller operations.
