  • More flexible battery design with ultrafast laser ablation

    Press Release / September 08, 2020

    Fast, gentle and reliable:  The Fraunhofer ILT has come up with a process tailor-made to ablate anode material from very thin copper foils at up to 1760 mm³/min. It uses a powerful USP laser to expose surfaces for electrical contacts.

    The ultrashort pulse (USP) laser has been known to shine whenever highly sensitive material needs to be machined quickly yet gently. The Fraunhofer Institute for Laser Technology ILT has investigated one such application that certainly looks to have a bright future: The Aachen-based researchers developed a quick, reliable and nondestructive method of ablating lithium-ion batteries’ anode material with an ultrashort pulsed laser beam. This ablation technique exposes electrical contact points called tabs.

  • Producing Nanostructures Cost-Effectively

    Press Release / September 03, 2020

    At Fraunhofer ILT, a laboratory system for EUV has been built to process wafers with a diameter of up to 100 mm.

    How can structures smaller than one micrometer be generated? And how can even smaller structures of less than 100 nanometers be produced without great effort? Scientists at the Fraunhofer Institute for Laser Technology ILT have developed several technologies to answer such questions. With these technologies, they can simulate, produce and measure periodic microstructures. They use phase-shifting transmission masks that can efficiently generate nanostructures down to 28 nanometers.

    Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

    For the fourth time, laser polishing will be the center of attention at the Fraunhofer Institute for Laser Technology ILT in Aachen on September 16 and 17, 2020. As a premiere, however, since the “4th Conference on Laser Polishing – LaP 2020” will take place virtually for the first time. On both days, due to the large number of international participants, the conference will start at 1:30 p.m. and end at 4:30 p.m. (both CET).

  • In the SeQuLas research project, the partners developed an electronically monitored process for gentle, high-precision laser transmission welding of small plastic components for medical technology (in the picture: microfluidic chip from Bartels Mikrotechnik).

    In the successfully completed NRW project SeQuLas, the Fraunhofer Institute for Laser Technology ILT and three industrial partners have developed a joining process that can be used to produce the smallest weld seams in transparent plastic components. The process makes use of a thulium fiber laser, which offers a particular advantage: Since plastics absorb the corresponding wavelength well, the process does not require additional absorbers such as soot. The process is particularly interesting for medical technology, as it should be used to increase flexibility and efficiency in industrial production.

    LASER World of PHOTONICS 2021 will be opening its doors in a year’s time. From June 21 to 24, 2021, the world’s leading photonics trade fair will once again be presenting innovations from the industry in Munich – this time under special circumstances due to the coronavirus crisis. After the economic slump, exhibitors and the SPECTARIS trade association see an excellent opportunity for LASER 2021 to provide impetus for economic recovery. Exhibitors can register now.

  • One of the key goals of the EU project ADIR is to recover valuable raw materials by disassembling electronic devices that are no longer in use.

    The EU project ADIR set out to develop a completely new, automated method of recycling electronic devices by disassembling them and recovering the valuable raw materials they contain. Under the title of “Next generation urban mining – Automated disassembly, separation and recovery of valuable materials from electronic equipment”, the ADIR project team has spent the last four years developing a sustainable recycling concept. Led by the Fraunhofer Institute for Laser Technology ILT, based in Aachen, Germany, and involving eight project partners from three countries, the ADIR project’s strategic goal is to reduce the EU’s dependency on natural resources, reduce the need for costly imports of raw materials, and demonstrate new technologies for inverse production.

  • How can Additive Manufacturing help in the fight against coronavirus? The EU project AMable calls for the submission of ideas in this area. In a second step, SMEs, for example, can submit solution concepts and receive funding.

    The coronavirus is currently paralyzing public and private life and in many places there is a lack of medical equipment and viable solutions to protect society against the spread of the virus. Together with institutions from all over Europe, the Fraunhofer Institute for Laser Technology ILT is supporting companies in the EU project AMable in implementing Additive Manufacturing ideas that will help overcome bottlenecks in this fight. Now that AMable has already successfully paved the way for SMEs to industrial 3D printing with metal and plastic, the partners are offering aid and public funding for COVID-19 projects. The AMable partners are calling for ideas to be submitted in a first step and applicable solutions for the additive manufacture of new products in a second step.

  • From May 4 to 6, 2022, the AKL – International Laser Technology Congress will once again take place in its usual form.

    Owing to the progressing coronavirus pandemic, the Fraunhofer Institute for Laser Technology ILT has decided to cancel the International Laser Technology Congress AKL in 2020. The safety and health of our attendees, partners and employees has top priority for us. The next AKL will take place from May 4 to 6, 2022, thus maintaining its regular biennial rhythm. However, so that interested parties do not have to wait another two years for the live demonstrations in Europe's largest laser system park, which are firmly anchored in the AKL, Fraunhofer ILT intends to open its doors as early as this autumn and in 2021 for various planned symposia in Aachen – provided that the general conditions allow it again.
