Sandblasting with Light

Sandblasting – that was yesterday. Laser beams can clean and structure surfaces more precisely, cost-effectively and in environmental friendlier ways than conventional systems. The Fraunhofer Institute for Material and Beam Technology IWS in Dresden has developed the technology “LIGHTblast” for this purpose which is now being transferred to the semiconductor manufacturing, automotive supply and other industries.

Fraunhofer project FibroPaths®: enabling rapid and safe development of antifibrotic drugs

More than 100 million individuals worldwide suffer from organ fibrosis, a pathological proliferation of connective tissue in an organ, such as the lung, heart and liver. Hardly any causal treatments are available to date. The unmet medical need is partly due to the fact that the existing disease models for fibrosis research are insufficient and little predictive. Coordinated by the Fraunhofer Institute for Toxicology and Experimental Medicine ITEM, four Fraunhofer institutes have joined forces in the FibroPaths® project aimed at enabling rapid and safe development of antifibrotic drugs.

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.
