    Extreme High-speed Laser Material Deposition EHLA, developed at the Fraunhofer Institute for Laser Technology ILT, is considered an efficient and environmentally friendly alternative to conventional cladding processes. It offers significant advantages, particularly for coating metallic components that are subject to extreme stress and, therefore, need to be protected from corrosion and wear. Together with Ponticon GmbH, scientists at Fraunhofer ILT are continuing to work on the patented process, now named EHLA 3D, to advance it for additive manufacturing and, thus, expand its possibilities many times over.

  • The online seminar “eHarsh” will present the development of new compact sensors for industrial processes in harsh environments.

    Eight Fraunhofer institutes have joined forces to develop sensor technology for extremely harsh environments. They will present the current status of their work in an online seminar from November 29 to December 3, 2021, showing details along the entire process chain. Viewers will have a “front row seat” during five live laboratory tours. This should be exciting for a wide range of industries: The applications of the new technology range from aviation to the chemical industry and the steel industry all the way to geothermal energy.

    Customers and investors are increasingly placing value on ecologically and sustainably manufactured products. By transparently and ecologically assessing their products, industry and SMEs (small and medium-sized enterprises) can take responsibility for people and the environment and position themselves in the market with a competitive advantage. Researchers at the Fraunhofer Institute for Laser Technology ILT are now addressing the topic of life-cycle assessment in Laser Powder Bed Fusion.

    The Fraunhofer Institute for Laser Technology ILT in Aachen has been developing and building laser systems for use in space for several years. At the same time, the Aachen scientists are also researching technologies for metallic 3D printing. Using the Laser Powder Bed Fusion (LPBF) process, Fraunhofer ILT – along with the Chair for Digital Additive Production DAP – has developed and set up a new precision gripper arm made of metal powder for the first time: a novelty for the assembly of space components in clean rooms. The gripper arm is lighter than its predecessor and yet stable enough to mount and adjust heavier laser optics with ultra-precision.

    At the second “AI for Laser Technology Conference” on September 28 and 29, 2021, participants will discuss how artificial intelligence is currently being applied in laser materials processing. Researchers and plant engineers, software developers and machine builders will meet here to exchange ideas. In addition to the technical presentations, the laboratories at the Fraunhofer Institute for Laser Technology ILT will be opened for virtual tours. Due to current regulations, the conference will take place online.

    Networking at its best – live on site! The Fraunhofer Institute for Laser Technology ILT invites the laser community to the 13th International Laser Technology Congress AKL from May 4 to 6, 2022. Laser manufacturers and users from various industries, experienced experts and newcomers, strategists and practitioners can catch up on the latest developments in the field of applied laser technology in production at AKL'22. Over three conference days, 87 presentations will bring participants up to date on the latest technology and give them insight into current research topics for tomorrow's production solutions. Along with the exhibition accompanying the conference and the live demonstrations at Fraunhofer ILT, the AKL has established itself as the central networking platform for the laser community.

    The Fraunhofer Institute for Laser Technology ILT has received an award for decades of development in the field of additive manufacturing: The Aachen-based institute won a competition conducted by ASTM International and is now working on a project towards standardization of machine condition monitoring in laser beam powder bed fusion (LB-PBF). It is focusing on selecting and qualifying imaging sensor technology that can be used to specifically monitor the condition of LB-PBF systems. Finally, the institute will derive cost-reducing recommendations for end users from these data.

    The LASER World of PHOTONICS Industry Days took place from June 21 to 24, 2021. With this online event, Messe München – organizer of the world's largest trade show for applied laser technology and photonics – offered its community a high-quality program including market overviews, trend analyses and panel discussions. Industrial laser technology today and tomorrow was one focus of the program.

  • A hybrid circuit board pro-duced as part of the BMWi-funded CLAPE project. It combines several functions in one component.

    Scientists at the Fraunhofer Institute for Laser Technology ILT, in collaboration with project partners, have succeeded in developing a novel industrial manufacturing process, one that makes it possible to use low-cost FR4 circuit board substrates in power electronics, for example in electric motors. Compared to conventional power electronics made of ceramics, the so-called hybrid printed circuit boards are not only much more versatile, but also up to 20 times cheaper. This could close a gap in the market in the medium term and, thus, make an important contribution to the mobility of the future.

    In the Cluster of Excellence “Internet of Production” (IoP), 200 scientists at RWTH Aachen University in cooperation with Fraunhofer ILT have set up a data center for controlling and monitoring industrial processes. The concept for this is based on a project for controlling laser systems developed at the Fraunhofer Institute for Laser Technology ILT and uses the open source software Kubernetes. A corresponding system has been running successfully at the institute for two years, and with it the institute can automatically and remotely install the software for new lasers in just a few minutes.
