13th “AKL – International Laser Technology Congress”:
May 4–6, 2022 in Aachen – Laser Technology Live already this year!

Owing to the progressing coronavirus pandemic, the Fraunhofer Institute for Laser Technology ILT has decided to organize the next “AKL – International Laser Technology Congress” in two years: The AKL’22 will take place in Aachen from May 4 to 6, 2022. Provided that the general conditions allow, Fraunhofer ILT intends to open its doors to various planned conferences in Aachen as early as autumn 2020 to ensure that interested parties do not have to wait two years for the live demonstrations, firmly anchored in the AKL, in Europe's largest laser system park.

Printed miniature loudspeaker listening into the future

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) ”.

„PhotonHub Europe“: Strengthening European competitiveness through industrial use of Photonics

A photonics network of pan-European scale will start in January 2021 as part of the EU Horizon 2020 program: The project „Photonics Digital Innovation Hub“– PhotonHub Europe for short – is designed to make small and medium-sized European companies fit for the future by supporting them in the use of photonic technologies. The „PhotonHub Europe“ expects more than 1000 new high-tech jobs and around one billion euros in sales by 2025. The Fraunhofer Institute for Laser Technology ILT coordinates one of the eight technology platforms. With its focus on laser-based production, this platform plays an important role in European photonics.

Fraunhofer Lighthouse Project futureAM Gets Metallic 3D Printing in Shape for Industrial Use

Accelerating the additive production of metal components by at least a factor of 10: With this goal in mind, the Fraunhofer-Gesellschaft launched the lighthouse project “futureAM – Next Generation Additive Manufacturing” in 2017. As the project ends in November 2020, six Fraunhofer institutes have made technological leaps forward in systems engineering, materials and process control as well as end-to-end digitalization, thus increasing the performance and cost-effectiveness of metal-based additive manufacturing along the entire process chain.

Laser welding processes for martensitic chromium steels ensure a future safe from collisions

Martensitic chromium steels are one of the steel grades with a future, steels that are ideal for automotive applications since they are both lightweight and corrosion resistant. These materials are particularly in demand for the design of collision-safe battery boxes for electric cars. For this reason, the Fraunhofer Institute for Laser Technology ILT in Aachen uses these sophisticated components as demonstration components for laser welding and heat treatment.
