DRYtraec® to become technology platform

The DRYtraec® coating process developed at the Fraunhofer Institute for Material and Beam Technology IWS allows the dry production of battery electrodes without toxic organic solvents or water. In particular, the space- and energy-intensive drying step of conventional wet-chemical coating processes is completely eliminated. In addition to environmental protection aspects, there is enormous potential for cost reduction in the battery cell production. The German Federal Ministry of Education and Research (BMBF) is now funding a project with 3.7 million euros that will develop the dry-coating technology into a holistic technology platform.

POWDERscreen monitors streams of powder into the laser melt

Additive manufacturing processes continue to grow in the automotive, aerospace and other industries. When complex components or unique parts need to be produced, an increasing number of companies are turning to industrial 3D printing. However, the run-in curves can still be quite long, especially for small batches, and the reject rates may be high at the beginning. The Fraunhofer Institute for Material and Beam Technology IWS Dresden therefore develops modern measurement and control technology that allow additive processes to be used much more effectively than before, for example for highly automated production lines. This includes the POWDERscreen – a unique powder measuring device for laser cladding. Fraunhofer IWS will demonstrate this innovative system in May 2022 during the “3. Fachtagung Werkstoffe und Additive Fertigung“ at the German Hygiene Museum in Dresden.

HICLAD® enables resilient laser cladding with high-power laser

High-power diode lasers with outputs of ten or more kilowatts open new application scenarios for laser cladding. Particularly sustainable and resource-efficient coatings can be produced and applied, for example in automotive, machine construction and other industries. Together with industrial partners, the Fraunhofer Institute for Material and Beam Technology IWS has developed applications and specific processes for this laser class to industry readiness under the label “HICLAD®”. The Dresden institute and its project partner Laserline will present some of these at the “LASER World of PHOTONICS” trade show in Munich at the end of April.
