    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.

    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.

    Ultrafast lasers have become a standard manufacturing tool for the display industry, with even more and even larger applications coming in the next few years. The technology and processes needed for these new applications were presented at the 6th “UKP-Workshop: Ultrafast Laser Technology”, held by the Fraunhofer Institute for Laser Technology ILT in Aachen on April 21 and 22, 2021. Their spectrum ranged from ultra-powerful beam sources to processes that can be used to enlarge the surface of a metal electrode, for the generation of hydrogen, a thousand times.

    Setting up high-performance production centers for battery cells is high on the current agenda of the automotive industry. The Fraunhofer Institute for Laser Technology ILT in Aachen is proactively working towards this goal: In the BMBF project “HoLiB” and the IGF project “MikroPuls”, for example, scientists from Aachen are investigating how laser technology can be used to economically contact and join dissimilar materials.

    Service robots can help ensure that buildings and means of transport are cleaned and disinfected regularly and with consistently high quality. Since October 2020, twelve institutions of the Fraunhofer-Gesellschaft have been working on the development of new technologies for this field of application. Led by Fraunhofer IPA, the partners are pooling their expertise in the “Mobile Disinfection" (MobDi) research project to contribute to a safe “New Normal” in times of pandemic. The project is part of the »Fraunhofer vs. Corona« action program.

    The Fraunhofer Institute for Laser Technology ILT's globally successful EHLA extreme high-speed laser material deposition process is not only turning heads. In the collaborative project EVEREST, the institute – along with three industrial partners – has developed process and system technology to efficiently repair and coat components and tested it on rollers. Now after successfully completing the project, the Aachen researchers want to establish the newly developed process chain in the industry. The goal is to coat long and large rollers and other rotating components with the EHLA process in a near-net-shape, both reliably and extremely efficiently.

    In order to help the industry have greater access to raw materials, the Fraunhofer Institute for Laser Technology ILT and Cronimet Ferroleg. GmbH have jointly developed a laser-based sorting process for metal scrap as part of the BMBF-funded “PLUS” project. A new sensor they have developed makes the recycling of metallic raw materials many times more efficient than previously possible. The EU project “REVaMP” goes one step further: In this project, Fraunhofer ILT experts have also been contributing their expertise in the field of materials analysis at the European level since January 2020, thus making an important international contribution to securing a resource-efficient supply of raw materials in the long term.

  • Printed miniature loudspeaker listening into the future

    Press Release / January 07, 2021

    Technical structures and any geometries can be applied to the wafer by means of inkjet printing, and functionalization takes place via laser radiation. The individual loudspeaker elements are then separated and integrated into an electronic environment.

    It has six corners and is about the size of a 1-cent piece: In an additive manufacturing process, miniature loudspeakers can be produced efficiently and cost-effectively as part of piezoelectric microelectromechanical systems - so-called piezo-MEMS - using a combination of inkjet printing and laser technology. This has been demonstrated by scientists at the Fraunhofer Institute for Laser Technology ILT, the Institute for Materials in Electrical Engineering 2 (IWE2) at RWTH Aachen University and the Fraunhofer Institute for Silicon Technology ISIT. The partners manufactured a corresponding demo component as part of the recently completed BMBF joint project “Generative Manufacturing of Efficient Piezo-MEMS for Microactuators (GENERATOR) ”.
