    Higher atmospheric layers are becoming more and more interesting for climate researchers, but the areas above 40 km are only directly accessible with sounding rockets. A newly developed LIDAR system (Light Detection and Ranging) with a diode-pumped alexandrite laser will soon make such research possible remotely. Scientists from the Leibniz-Institute of Atmospheric Physics (IAP) and the Fraunhofer Institute for Laser Technology ILT are developing a system that is not only easy to transport but also works independently. In the future, a LIDAR network will be able to deliver data from the atmosphere continuously and on a large scale.

    Following a successful premiere in 2019, the Fraunhofer Institute for Laser Technology ILT will kick off the second Laser Symposium on Electromobility – LSE’20 – in Aachen on February 12, 2020. The two-day event will focus on high-efficiency laser techniques for every step in the process chain for producing batteries and electric vehicles. One of the main highlights will be a presentation from Swiss company E-Force One AG on the electrification of heavy-duty transportation.

    A spin-off of the Fraunhofer Institute for Laser Technology ILT receives a special distinction: the Aachen-based company Laser Melting Innovations GmbH & Co. KG is one of the winners of the “formnext Start-up Challenge” 2019. The young Aachen scientists will be honored by the jury for the development of their low-cost system on November 19 at the formnext in Frankfurt on the AM4U stage (hall 11.0-F71). With this system for Laser Powder Bed Fusion (LPBF) with metal powder, SMEs in particular have at their disposal an industry-suitable system technology for metallic 3D printing.

    Tungsten carbide-cobalt is an excellent material for cutting tools as it is extremely heat- and wear-resistant. In the new research project “Additive Manufacturing of Machining Tools out of WC-Co – AM of WC-Co”, scientists from the Institute for Materials Applications in Mechanical Engineering IWM and the Laboratory for Machine Tools and Production Engineering WZL of RWTH Aachen University as well as from the Fraunhofer Institute for Laser Technology ILT are now investigating how Laser Powder Bed Fusion can be used to process this material. It aims to additively produce cutting tools that achieve longer tool life thanks to complex cooling geometries.

    Transporting quantum information over long distances with glass fibers and paving the way for the quantum Internet: With this goal in mind, the Dutch research center QuTech and the Fraunhofer Institute for Laser Technology ILT launched the ICON project QFC-4-1QID on September 1, 2019. In this long-term strategic partnership between the research institutions, the scientists will be developing quantum frequency converters that will connect quantum processors to fiber optic networks. The new technology will be used in the world's first quantum Internet demonstrator in 2022.

    In the Fraunhofer lighthouse project “futureAM – Next Generation Additive Manufacturing,” an alliance of six Fraunhofer institutes shall accelerate 3D printing with metal powder by at least a factor of ten. The first tangible results prove that this is not a dream of the future. The futureAM team will be presenting these results at the joint Fraunhofer booth D51 in Hall 11 during formnext from November 19 to 22, 2019 in Frankfurt am Main.

    The market for additive processes continues to grow by around 20 percent annually and has reached a volume of 10 billion euros. This was reported by the organizer of formnext, the world's leading trade fair for additive manufacturing (AM) in Frankfurt. In AM, the trend is clearly moving towards greater productivity. Thanks to its new materials, lasers for eMobility and highly efficient 3D coating processes, the Fraunhofer Institute for Laser Technology ILT is providing the right ideas at the right time.

    Within a BMBF-funded project, the Fraunhofer Institute for Laser Technology ILT is tackling the issue of 3D printing large components economically by using a new process called Hybrid AM that combines conventional manufacturing with additive processes. An important step forward in this process development is a new wire LMD head and its modular components which the Aachen-based experts will be presenting for the first time at formnext from November 19 to 22, 2019 in Frankfurt am Main.
