  • Fraunhofer IWS prints heaters for space flight / 2020

    Hot patterns in cold space

    Press release (No. 6) - Fraunhofer IWS Dresden / June 25, 2020

    After insulating with a thin ceramic coating in a thermal spray system, the heating elements are applied with a dispense printing machine, which resemble the shape of a meander. If an electrical current flows through the metallic meander, it will release heat.

    Building satellites and spaceships is anything but cheap. One reason is the fact that cosmic technology must be designed far more fail-safe than on earth. In space, even minimal problems such as an iced battery can lead to dramatic consequences. The Fraunhofer Institute for Material and Beam Technology IWS Dresden has therefore now developed special reliable thin ceramic-silver heaters for Airbus. These can be continuously and automatically printed onto tubes and other highly complex-shaped components.

  • Dresden scientists develop self-cleaning aluminum surface / 2020

    Clean without scrubbing and using chemicals

    Press release (No. 5) - Fraunhofer IWS Dresden / May 27, 2020

    Dresden scientists have developed a self-cleaning metallic surface. A project team of the Technische Universität Dresden and the Fraunhofer Institute for Material and Beam Technology IWS structured an aluminum plate with a laser process in such a way that water droplets can roll at its surface and thus remove dirt particles – completely without chemical cleaning agents or additional effort. The scientific evidence of the self-cleaning effect has been published in the journal “Applied Surface Science”.

  • Surfaces functionalized with lasers / 2020

    A fast, ecofriendly way of de-icing aircrafts

    Press release (No. 4) - Fraunhofer IWS Dresden / March 02, 2020

    Direct Laser Interference Patterning (DLIP) can create complex, meandering surface structures on the micron and submicron scale to decrease ice accumulation and accelerate de-icing.

    Ice on an aircraft’s surfaces can be a hazard. It increases drag and fuel consumption, disrupts aerodynamic flows, and decreases lift – which impairs the aircraft’s ability to fly safely. Researchers at the Fraunhofer Institute for Material and Beam Technology IWS, AIRBUS and TU Dresden have developed a laser process that fills two needs with one deed. On one hand, accumulated ice falls off by itself and on the other it takes less heat to de-ice surfaces. Direct Laser Interference Patterning permits surfaces to be structured in ways that effectively repel ice.

    Microlaunchers are an alternative to conventional launch vehicles. Able to carry payloads of up to 350 kilograms, these midsized transport systems are designed to launch small satellites into space. Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden and TU Dresden’s aerospace experts developed an additively manufactured rocket engine with an aerospike nozzle for microlaunchers. The scaled metal prototype is expected to consume 30 percent less fuel than conventional engines. It will feature prominently at the Hannover Messe Preview on February 12 and in the showcase at booth C18 in hall 16 at the Hannover Messe from April 20 through 24, 2020.

  • “COAXshield” and “LIsec”: Fraunhofer IWS presents shielding gas nozzle and light scanner for laser powder build-up welding at “formnext” trade fair / 2019

    Fine-tuning for additive production

    Press release (No. 14) - Fraunhofer IWS Dresden / November 14, 2019

    “COAXshield” – novel local shielding nozzle system for laser metal deposition applications with sensitive materials

    Additive manufacturing systems can generate highly complex components, which could not be produced with conventional machine tools or only with great effort. Nevertheless, such industrial 3D printers are far from being standard equipment in factories. This is not just due to the purchase costs, but also to many other challenges. The Fraunhofer Institute for Material and Beam Technology IWS Dresden has developed particular solutions and will present them at the “formnext” trade fair in Frankfurt am Main in November 2019. Included here are “COAXshield”, a local molten pool shield for laser powder build-up welding and the “LIsec” analysis device for controlling the powder flow in additive manufacturing processes.

  • New thin-film electrodes made of silicon and lithium for the “Research Fab Battery” / 2019

    “KaSiLi”: Better batteries for electric cars “Made in Germany”

    In the umbrella concept “Research Fab Battery”, German scientists want to develop novel batteries that are capable of storing at least 70 percent more energy for electric vehicles and smartphones than conventional lithium-ion solutions while maintaining the same volume. As part of the cluster of competence for battery materials “ExcellBattMat“ funded by the Federal Ministry of Education and Research (BMBF), Dresden's “ExcellBattMat Center” (project KaSiLi: structural cathode adaptation for silicon and lithium materials) contributes key components for this new battery generation. On November 1, 2019, researchers from Fraunhofer, TU Dresden and Leibniz started working together on innovative battery electrodes consisting of ultra-thin silicon or lithium layers to achieve high energy densities.

  • Symposium in Dresden focuses on a new class of materials / 2019

    High entropy alloys for hot turbines and tireless metal-forming presses

    Press release (No. 13) - Fraunhofer IWS Dresden / November 05, 2019

    For the first time, scientists at Fraunhofer IWS printed 3D high-entropy demonstrator structures made of the Cantor alloy "CrMnFeCoNi" using the Fused Filament Fabrication (FFF) process. On the surface, the illustration shows an example of a particularly high-strength microstructure consisting of two phases as a planned further alloy system development.

    A new class of materials promises many innovations in aviation, turbine construction and other branches of industry: High entropy alloys (HEA) are metals in which five or more elements are atomically bonded in similar proportions. Properly designed, they are harder, more heat-resistant and lighter than steel, aluminum and other classic materials. For about 15 years, engineers around the world have been trying to make these innovative materials ready for series production. But high-entropy alloys are still too expensive and difficult to process. The Fraunhofer Institute for Material and Beam Technology IWS Dresden is therefore now inviting experts to a symposium in March 2020 to demonstrate how they can overcome these problems – for example through industrial 3D printing, in other words “Additive Manufacturing”. Fraunhofer IWS will give a first insight with the lecture “High entropy alloys for Additive Manufacturing” on November 21, 2019, 2:15 p.m. at the “TCT Introducing Stage” during the “Formnext” trade fair in Frankfurt am Main, Germany.

  • Environmentally friendly: IWS Dresden ceramic coatings can reduce engine exhaust gases / 2019

    Heat shields for economical aircrafts

    To make aircrafts more economical, environmentally friendly and robust, Fraunhofer engineers from Dresden have developed a new ceramic heat shield technology. In this process, a powder of yttrium-stabilized zirconium oxide (YSZ) is added to water to form a suspension. Quickly and cost-effectively this liquid powder mixture can be sprayed onto turbine blades or other aircraft parts. Such and similar thermal barrier coatings (TBCs) facilitate aircraft engines, which consume less fuel and do not contaminate the atmosphere as much.
