    North Rhine-Westphalia has launched the NRW Leitmarkt project AddSteel, which is aimed at digitalizing the steel industry. Coordinated by SMS group GmbH, a plant engineering company based in Mönchengladbach, this three-year project will develop new function-adapted steel materials for additive manufacturing. One of the project’s key areas of focus is the qualification of the developed materials for laser powder bed fusion (LPBF), a metallic 3D printing process, at the Fraunhofer Institute for Laser Technology ILT in Aachen. One of the AddSteel project team’s first successes was the development of the first case-hardening and heat-treatable steel powders designed specifically for LPBF applications.

    Throughout his professional life, Prof. Reinhart Poprawe shaped technological progress in photonics and specifically built up the next generation of young talent for the industry. Now the laser visionary is retiring in the fall of 2019. At the symposium “Digital Photonic Production and Industrie 4.0 and what it means for education and research” 280 laser experts and companions paid tribute to his work as a professor of laser technology, his services in basic and contract research and in the networking of industry and science. The symposium took place on June 23, 2019 in the run-up to the world's leading trade fair LASER World of PHOTONICS in Munich.

    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".

  • Reduced reworking and creation of selective polishing effects through the sequential process of USP laser cleaning and USP polishing after structure generation.
    © Fraunhofer ILT, Aachen, Germany / Volker Lannert.

    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.
