At Stand 4211 in Hall 4 of Fakuma (October 13 - 17, 2009, Messe Friedrichshafen), the Fraunhofer ILT will be presenting a novel, compact and industry-ready plant concept to laser weld plastics using fiber lasers.
Bonding metal to plastic with a laser-structured metallic surface and subsequent extrusion.
A TWIST®-welded microfluidics component, minimal canal width < 50 µm.
Thanks to the TWIST® radiation concept, a quick, temporal and localized beam modulation forms the basis for this new laser method. Fraunhofer ILT's researchers in Aachen have developed and qualified TWIST® - "Transmission Welding by an Incremental Scanning Technique" - an innovative process to weld plastics.
When compared to standardized laser plastic welding plants, this new concept significantly reduces investment costs as well as plant size, and is nearly maintenance-free. Furthermore, the TWIST® plant concept is characterized by its higher process speed and flexibility when structuring welding contours, as compared to conventional joining methods. Hence, it is particularly suitable for small and medium series, which require quick retooling. By using new wave lengths in combination with the TWIST® concept, operators are now able to weld transparent components together without an infrared absorber and at high speeds.
To bond metal with commercially available plastics, the Fraunhofer ILT has developed a laser-supported joining process that can dispense with using additional material. A suitable structuring of the metal's surface at high speed allows form fit joints to be attained above the bonds with high strength.Contact person at the Fraunhofer ILT

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
