    The Fraunhofer Institute for Laser Technology ILT has taken its “TwoCure” process to the next level by developing it into an industry-ready machine technology. The team of scientists from Aachen, Germany will be presenting their “TwoCure” system at formnext in Frankfurt am Main from November 13 to 16. The new technique uses resin-based 3D printing to produce large numbers of plastic components without support structures in an automated process.

    Additive manufacturing processes are booming, with the rapid growth of the formnext trade fair a clear indication of this. At formnext 2018, in cooperation with the Chair for Technology of Optical Systems TOS at RWTH Aachen University, the Fraunhofer Institute for Laser Technology ILT will be showing a new process in which the component in the powder bed is heated with laser diodes. As a result, distortion can be reduced, taller parts generated and new materials used.

    Since it oversees such a large number of projects, the Fraunhofer Institute for Laser Technology ILT from Aachen is increasingly faced with the agony of choice: Which innovations should it present at an industrial exhibition or a congress? At EuroBLECH, from October 23 to 26, 2018 in Hanover, the Aachen scientists will be presenting five groundbreaking developments on all major trends in contemporary sheet metal processing – from hybrid lightweight construction to multifunctional laser robots with an integrated digital twin.

    The relentless advance in the digitalization of production is making inroads into the manufacture of premium quality optical plastic components: More and more frequently, digital applications help to model production processes more dependably and more predictably and to produce plastic optical components more swiftly and accurately. This is enabling plastic optical components to be produced with greater precision and reliability. At the Fakuma International Trade Fair for Plastics Processing which takes place 16 - 20 October 2018 in Friedrichshafen, the Fraunhofer Institutes IPT and ILT in Aachen along with the IKV at RWTH Aachen University will be providing an insight into new technologies and applications for the manufacture of optical elements made of a range of plastic materials in Hall B4 at the joint Kunststoffland-NRW e.V. Booth (Booth 4404).

  • Surface Finishing at High Speed

    Press Release / 7.8.2018

    High precision and high quality, but too slow – this is how most laser processes for surface finishing can be described. In the EU research project ultraSURFACE, the Fraunhofer Institute for Laser Technology ILT in Aachen, together with nine international partners, is developing two new optics by the end of 2018. With them, the laser beam shape can be specifically and quickly adapted to constantly changing processing situations. In the near future, lasers will be able to polish, coat or structure surfaces up to ten times faster than before thanks to this tuning.

    The research team of the Fraunhofer Institute for Laser Technology ILT and the Chair of Digital Additive Production DAP of RWTH Aachen University will be honored with the Berthold Leibinger Innovationspreis 2018 for their development of the “Extreme High-Speed Laser Material Deposition” (EHLA). This process can be used to coat, repair or additively manufacture components in a particularly economical and environmentally friendly way. On September 21, the Aachen scientists will receive the first prize of the laser innovation prize awarded by the private foundation Berthold Leibinger Stiftung in Ditzingen, Germany, every other year since 2000 for outstanding research and development on the application or generation of laser light.

  • 3D-Printing: Support structures to prevent vibrations in post-processing operations for thin-walled parts

    Press Release of the Fraunhofer Institute for Production Technology IPT / 16.7.2018

    Support structures for the reduction of vibrations during the post processing by milling.

    One of the main features of additive manufacturing processes such as 3D-printing is that the complexity of the component shapes it produces, is virtually unlimited. However, high surface quality in metallic components can frequently be achieved only via milling or grinding finishing operations. Milling operations conducted on thin-walled parts in particular often cause vibrations which impact negatively on part accuracy and on machining time. The Fraunhofer Institute for Production Technology IPT and the Fraunhofer Institute for Laser Technology ILT in Aachen will be presenting special-purpose support structures which can eliminate these vibrations in post-processing operations at Farnborough International Airshow from 16 – 22 July 2018.
