Clean lungs thanks to laser process exhaustion

In sectors such as the automotive industry, components can be processed at extremely high speed using the laser remote process. However, this can result in harmful emissions which may cause lung damage. Scientists from the Dresden Fraunhofer Institute for Material and Beam Technology IWS have studied the issue as part of the IGF research project “CleanRemote”. They reduce particles and gases in the air by means of a suction device.

Economical energy storage for the electric car of tomorrow

Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed a new production process with the aim of efficient and environmentally friendly future battery production. They coat the electrodes of the energy storage cells with a dry film instead of liquid chemicals. This simplified process saves energy and eliminates toxic solvents. A Finnish company is currently successfully testing the new IWS technology in practice.

Waterproof thanks to rapid lasers

Fraunhofer engineers from Dresden have developed a new laser welding process employing a fast oscillating laser beam. This technology, known as "remoweld®FLEX", is suitable for particularly demanding processes – especially for components to be sealed media-tight against water and other undesirable environmental influences. These include housings for electrical and electronic components, heat exchangers and coolings, which have previously been regarded as hardly weldable and often consist of die-cast aluminum. The Fraunhofer Institute for Material and Beam Technology IWS and Maschinenfabrik Arnold from Ravensburg were both involved in the research development.

Additive machines discover superalloys

Scientists at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed innovative methods enabling more materials to be processed in additive manufacturing than ever before. For example, additive manufacturing systems could facilitate better future aircraft engines with lower fuel consumption. However, engineers must first improve the current industrial 3D printers in such a way that these machines can also process very strong and extremely heat-resistant alloys. Here, the Dresden researchers rely on their profound experience with laser powder buildup welding technologies and employ artificial intelligence (AI). They contribute their profound materials expertise to the Fraunhofer joint project "futureAM". The aim of the partners is to speed up additive manufacturing systems for metal components by a factor ten and also to manage superalloys.
