Mass-production of functionalised surfaces to be used in consumer market
A laser machine capable of producing large-area functionalised surfaces at high-throughput is being developed for the domestic appliance market in a collaborative European research project. The three-year ‘LAMpAS’ project, which began in January, has been funded €5.1m under Horizon 2020 in a public-private partnership with Photonics21. The project will combine high-average-
power ultrafast lasers, direct laser interference patterning and polygon scanner processing to enable the mass- production of micro- and nanostructures on a range of surfaces. These structures, inspired by those found
in nature on the leaves of the lotus flower or the wings of a butterfly, will provide antibacterial and self-cleaning properties, in addition to friction reduction, optical security functions and decorative effects. Project coordinator Professor Andrés
Lasagni, of TU Dresden, said: ‘The results envisioned in LAMpAS will make possible the production of a new generation of electrical appliance, as well as food packaging systems, by adding new functionalities to the surfaces of daily used devices. ‘We are very pleased to bring together the main industrial players for developing this new laser-based system for large-volume production. We are sure the results will be ground-breaking for various industries.’
In addition to TU Dresden, partners
of the LAMpAS project include: Trumpf, Lasea, Bosch, BSH Hausgeräte, Next Scan Technology, New Infrared Technologies (NIT) and the European Photonics Industry Consortium (EPIC). The laser machine under development will
incorporate advances in high-power ultra- short pulsed lasers, advanced scanning techniques for new beam delivery concepts, interference patterning optics, and a real- time monitoring system. Producing the functionalised surfaces using laser processing, rather than with coatings, will not only increase the durability of the surfaces, but will also be a more environmentally friendly process.
Hamamatsu develops laser- diode-pumped pulsed laser system delivering 117J
Hamamatsu Photonics has developed technology for efficiently cooling a laser medium, and as a result has developed a laser-diode- pumped high-energy pulsed laser system that delivers an output of 117J – the world’s highest among laser-diode- pumped lasers, according to the firm. The newly developed laser
system, which operates at 1,030nm wavelength and offers 40ns pulse width, will further enhance the laser peening effect used for hardening the surfaces of metal materials in aircraft and automobiles. The system will also prove a powerful assist for new laser processing applications, such as laser forming for shaping metal materials, and paint removal. The system was
developed by the ‘Research and Development of Next Generation Laser Processing Technology’ project, supported by the New Energy and Industrial Technology Development Organization (NEDO) – a national research and development agency in Japan. It was presented at OPIC 2019 in Pacifico Yokohama in April.
