Lasern in 3-D

(PresseBox) (München, )
Lasern statt Ätzen: Auf der LASER 2007 in München vom 18. bis 21. Juni stellen Fraunhofer-Forscher eine Anlage vor, die mit Laserlicht hauchfeine Mikrostrukturen in komplex geformte Bauteiloberflächen brennt. Die Technik ist kostengünstiger und umweltfreundlicher als traditionelle Ätzverfahren.

Kleine Struktur, große Wirkung. Mikrometer feine Muster in Oberflächen verleihen Bauteilen verblüffende Eigenschaften: Armaturen-bretter aus Kunststoff beispielsweise sehen aus wie Leder; Haifischhaut-Rippen am Flugzeugrumpf verringern den Luftwiderstand; Mikrovertiefungen in Implantaten verbessern die Verbindung mit dem Knochen. Es gibt viele Gründe, Werkstücke mit Mikrostrukturen zu versehen. Doch sie aufzubringen ist alles andere als einfach.
