    The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bidirectional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.

    In the new infrastructure project NextGenBat, six institutes are paving the way for the research and development of future battery systems. RWTH Aachen University, Forschungszentrum Jülich and the Fraunhofer Institute for Laser Technology ILT are involved in the project, which will particularly strengthen the federal state North Rhine-Westphalia as a high-tech location for energy storage development. NextGenBat was launched on September 5, 2018 within the “Research Infrastructures“ funding initiative of North Rhine-Westphalia as part of the operational NRW-EFRE program.

    Cutting, welding and additive manufacturing with one laser in one machine – this innovation, which gives the sheet metal processing industry significant productivity and quality advantages, is the focus of MultiPROmobil, an NRW Leitmarkt Project. Four partners are developing multi-functional laser tools to master the changing production and technical challenges of new, electric vehicle designs. The Fraunhofer Institute for Laser Technology ILT is coordinating the project, which started on November 15, 2018 and will appeal in particular to small- and medium-sized companies.

    Since 2015, nine project partners from four countries have been researching how to disassemble electronics and reclaim economically strategic materials in the EU project "ADIR – Next Generation Urban Mining – Automated Disassembly, Separation and Recovery of Valuable Materials from Electronic Equipment". On May 17, 2019, the project partners presented important results in theory and practice at the ADIR Demo Day in Goslar. On the agenda stood an introduction lecture from the Federal Environment Agency and a series of presentations held by the project partners of the ADIR consortium. Recent developments in the project were presented by Prof. Reinhard Noll from the Fraunhofer Institute for Laser Technology ILT. Processes and machines of the ADIR demonstrator were exhibited to the scientific-technical audience. Key concepts in the course of that are "Urban Mining" as well as the "Inverse Production".

    Experts from 13 different Fraunhofer institutes are working on the development of multi-kW ultrafast lasers and various applications in the Fraunhofer Cluster of Excellence Advanced Photon Sources CAPS. A user facility with application laboratories in Aachen and Jena is being created for this purpose, laboratories in which partners from industry and research can work with the new technology.

    Car makers currently use a variety of methods to emboss plastic panels for vehicle interiors. However, manufacturing the tools required for this purpose is an extremely time-consuming process. This situation can be improved using a new laser machine that triples the rate at which these tools are produced while facilitating even more complex structures. The expertise required for the various components and processes was developed as part of the “eVerest“ project in collaboration with partners from research and industry.

    It is only an inconspicuous piece of paper, but it is an important milestone for autonomous driving: At the end of 2018 the three partners from the joint research project RadarGlass applied for a patent for an innovative radar system. The Fraunhofer Institute for Laser Technology ILT from Aachen, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP from Dresden and the Institute of High Frequency Technology IHF of RWTH Aachen University have developed a coating process chain that enables radar sensors to be integrated in car headlights. After almost two years in development they have manufactured a working prototype.

  • USP Lasers Conquer Macroprocessing

    Press Release / 25.4.2019

    Dr. Arnold Gillner: The challenge is to get the photons to the workpiece.
    © Fraunhofer ILT, Aachen, Germany.

    Ultrashort pulse (USP) lasers have become firmly established in science and micromachining. At this year's “UKP-Workshop: Ultrafast Laser Technology” in Aachen, a new trend has emerged: Macroprocessing. Since multi-100-watt USP lasers up into the kW range have become available, the industry is looking at them with great interest for large-area applications. For this purpose, the institute is developing the complete process chain right through to fully digitized processes.

    It was a start with far-reaching appeal: On March 27, 2019, the joint project IDAM held its kick-off meeting in Munich, which was intended to pave the way for Additive Manufacturing to enter automotive series production. Specifically, the project partners – consisting of SMEs, large companies and research institutions – will transfer metallic 3D printing into an industrialized and highly automated series process in the automotive industry for the first time. The Fraunhofer Institute for Laser Technology ILT in Aachen and the Chair for Digital Additive Production DAP of RWTH Aachen University are supporting the project through their many years of experience in the field of additive manufacturing technologies.

    No e-mobility without laser technology: this is one of the claims of LASER World of PHOTONICS 2019. In keeping with the theme of this year’s fair, the Fraunhofer Institute for Laser Technology ILT will be using Laser-Based Tape-Automated Bonding (LaserTAB) to demonstrate how even the most diverse battery cells and power electronics can be combined quickly, reliably and efficiently using robot-assisted laser micro welding. At the Fraunhofer joint booth 431, hall A2, visitors can admire the electric racing car "eace05" of the Ecurie Aix - Formula Student Team, RWTH Aachen. An excellent example for the use of laser technology in electromobility, containing laser-welded batteries as well as laser-cut CFK-components.
