    The Fraunhofer Institute for Laser Technology ILT, Aachen, Germany is presenting two highlights at the LASER World of PHOTONICS China Shanghai from March 20-22. The specialty of helical optic is ultra high quality and high precision micro-machining. The extreme high-speed laser material deposition EHLA shows how the patented invention has already proved itself as an alternative to hard chrome plating and thermal spraying for metal components that must withstand powerful stresses.

    Either fast or precise – both cannot be achieved in the production of the finest polymer structures with the laser. Or maybe they can? Combining stereolithography and multiphoton polymerization should make it possible: Scientists at the Fraunhofer Institute for Laser Technology ILT are developing a machine for high-precision, cost-effective 3D construction technologies using both methods. On November 1, 2018, Fraunhofer ILT and its project partners launched the project “High Productivity and Detail in Additive Manufacturing through the Combination of UV Polymerization and Multi-Photon Polymerization – HoPro-3D”, which is funded by the European Union and the state of North Rhine-Westphalia.

    Lasers with ultrashort pulses in the picosecond and femtosecond range are often referred to as ultrafast lasers. They are known for their ultra-precise ablation and cutting results. Unfortunately, processing with such lasers takes time. To address this issue, a new research project, funded by the European Commission, aims to make material processing with ultrafast lasers up to a hundred times faster.

    On February 20, 2019 in Aachen, the practical applications will be the focus of the first Laser Symposium on Electromobility (LSE 2019): The Fraunhofer Institute for Laser Technology ILT invites you to ten lectures with experts from industry and research, who will present new laser-based production methods for the production of battery modules and packs.

    Separate glass with any desired contour? Without generating dust and reworking the edges? This is possible, even quickly, with specially shaped ultrashort laser pulses. The Fraunhofer Institute for Laser Technology ILT is developing a technology that – with refractive and diffractive optical elements – gives laser beams a form optimally adapted to the respective task. In addition, the applications go far beyond separating glass: In the future, head-up displays for the automotive industry will also be produced.

  • ICTM Conference 2019 in Aachen: Digitalization emerges as a leading-edge engineering trend for turbomachinery construction

    Press Release of the Fraunhofer Institute for Production Technology IPT and the Fraunhofer Institute for Laser Technology ILT / 11.12.2018

    All data is digitally captured and stored in the cloud – one of the central topics of the ICTM Conference is how the digital twin accompanies the component through its entire life cycle.

    Digitalization of the production process has allowed turbomachinery components to be manufactured more efficiently than ever before: The core question to be addressed at what is now the fifth ICTM Conference to take place 6 and 7 February 2019 in Aachen and hosted by the Fraunhofer Institutes in Aachen is “How do high levels of data consistency, continuity and availability along with more robust processes and greater production transparency result in a more economically efficient process chain?” Online enrolment for conference attendance is now open and there is an early-bird discount for bookings made by 17 December 2018.

    Five companies and two research institutes were involved in one of the most exciting technical issues in production. Coordinated by Daimler AG and within the framework of the BMBF funding initiative “Photonic Process Chains”, these project partners examined the “Integration of Additive Manufacturing Processes in Automobile Series Production – AutoAdd”. They focused on the metallic, additive manufacturing process developed at the Fraunhofer Institute for Laser Technology ILT in Aachen, Germany: Laser Powder Bed Fusion (LPBF), also known as Selective Laser Melting (SLM).

    The “Conference on Laser Polishing – LaP” at the Fraunhofer Institute for Laser Technology ILT is an international meeting point for all experts using or researching laser polishing. For the third time, the conference took place in Aachen and offered a comprehensive overview of research results and trends relating to the industrial use of laser polishing for metals, glass and plastics. On September 12 and 13, some 80 participants from a total of 15 different countries exchanged knowledge as well as ideas and gained insights into the laboratories at Fraunhofer ILT.

    The future of 3D printing will be the focus at formnext 2018 in Frankfurt am Main. For this, the Fraunhofer Focus Project futureAM offers particularly exciting insights, a project in which six Fraunhofer institutes are involved. The partners are doing both, comprehensively looking at digital and physical added value right from the order to the finished component; and at the leap into a new technology generation of additive manufacturing.

    Having received a Joseph von Fraunhofer Prize in 2017, a research team from Aachen has now also won the prestigious Berthold Leibinger Innovationspreis. Their award-winning process “Extreme High-Speed Laser Material Deposition” is known by its German abbreviation, EHLA. The technology allows protective metal coatings to be applied at extremely high speeds in a cost-effective and environmentally friendly manner. EHLA is also a model of successful cooperation based on partnership and of how to solve practical, application-oriented problems. In addition, it exemplifies how the Fraunhofer-Gesellschaft works.
