    Ultrashort pulse (USP) lasers have become firmly established in science and micromachining. At this year's “UKP-Workshop: Ultrafast Laser Technology” in Aachen, a new trend has emerged: Macroprocessing. Since multi-100-watt USP lasers up into the kW range have become available, the industry is looking at them with great interest for large-area applications. For this purpose, the institute is developing the complete process chain right through to fully digitized processes.

    It was a start with far-reaching appeal: On March 27, 2019, the joint project IDAM held its kick-off meeting in Munich, which was intended to pave the way for Additive Manufacturing to enter automotive series production. Specifically, the project partners – consisting of SMEs, large companies and research institutions – will transfer metallic 3D printing into an industrialized and highly automated series process in the automotive industry for the first time. The Fraunhofer Institute for Laser Technology ILT in Aachen and the Chair for Digital Additive Production DAP of RWTH Aachen University are supporting the project through their many years of experience in the field of additive manufacturing technologies.

    No e-mobility without laser technology: this is one of the claims of LASER World of PHOTONICS 2019. In keeping with the theme of this year’s fair, the Fraunhofer Institute for Laser Technology ILT will be using Laser-Based Tape-Automated Bonding (LaserTAB) to demonstrate how even the most diverse battery cells and power electronics can be combined quickly, reliably and efficiently using robot-assisted laser micro welding. At the Fraunhofer joint booth 431, hall A2, visitors can admire the electric racing car "eace05" of the Ecurie Aix - Formula Student Team, RWTH Aachen. An excellent example for the use of laser technology in electromobility, containing laser-welded batteries as well as laser-cut CFK-components.

    Since 2015, nine project partners from four countries have been researching how to disassemble electronics and reclaim valuable materials in the EU project "ADIR – Next Generation Urban Mining – Automated Disassembly, Separation and Recovery of Valuable Materials from Electronic Equipment". On May 17, 2019, the project partners will present important results in theory and practice at the ADIR Demo Day in Goslar. The ADIR project is coordinated by the Fraunhofer Institute for Laser Technology ILT in Aachen, Germany.

  • Direct printing: The Fraunhofer ILT is demonstrating a strain gauge sensor that can be applied directly and automatically to the component thanks to a combination of printing and laser technology.

    In recent years, the demands placed on component-integrated electronics have risen so sharply in many industries that they can often no longer be met with conventional electronic components. As an alternative, printed electronics is on the advance. At the Hanover Fair from April 1 to 5, 2019, experts from the Fraunhofer Institute for Laser Technology ILT in Aachen, Germany, will be demonstrating the role lasers play in this process. Highlights include the directly printed strain gauge sensor, the locally gold-plated contacts and the electrically conductive glass fiber fabric.

    A new term was coined recently at the “5th Conference of the ICTM International Center for Turbomachinery Manufacturing Aachen”, which was held on February 6 and 7, 2019. Some 200 participants from 18 countries discussed the best ways to achieve an “ecolonomic” form of turbomachinery manufacturing and deployment – in other words one that reduces both their cost and environmental impact.

  • High power rates and small spacings between the holes require targeted thermal process management also in USP multibeam processes. This can be achieved with optimized process control.

    A new generation of ultrafast process technology is on the market. Higher average laser power and greater pulse energy promise higher throughput and efficiency. When processing microfilters, for example, this makes it possible to drill hole sizes down to below one micrometer much more quickly. When scaling the processes, there are some non-trivial interaction mechanisms to contend with, which were one of the topics of the “5th UKP-Workshop: Ultrafast Laser Technology“ in Aachen.

  • Light and strong: Hybrid lightweight components made of steel and fiber-reinforced plastics

    Press Release of the Fraunhofer Institute for Production Technology IPT / 8.3.2019

    In recent years there has been a sharp increase in demand for lighter components for applications in mobility and transport in response to the need to save weight, and therefore energy and resources. Hybrid components made of steel, locally functionalized with fiber-reinforced plastics combine high mechanical performance with low weight. Demand for manufacturing processes conducive to cost-effective mass-production is burgeoning. In the EU research project “ComMUnion”, the two Aachen-based Fraunhofer Institutes for Production Technology IPT and for Laser Technology ILT, in collaboration with 14 partners from industry, research and academia, are developing industrial processes and solutions for hybrid lightweight design by combining metal and polymer-matrix composites for automotive and aerospace applications.

    Since composites combine the advantages of dissimilar materials, they can be used to exploit great potential in lightweight construction. At JEC World 2019 in Paris in March, scientists from the Fraunhofer Institute for Laser Technology ILT will present a broad range of laser-based technologies for the efficient production and processing of composite materials. Visitors to the joint booth of the Aachen Center for Integrative Lightweight Construction AZL, Hall 5A/D17, will gain insight into joining and cutting processes as well as surface structuring.
