The 3D Valley Conference from September 25-27, 2018 focuses on industrial applications, shows new developments in processes, integrated process chains and innovative business models in the field of additive manufacturing.
High precision and high quality, but too slow – this is how most laser processes for surface finishing can be described. In the EU research project ultraSURFACE, the Fraunhofer Institute for Laser Technology ILT in Aachen, together with nine international partners, is developing two new optics by the end of 2018. With them, the laser beam shape can be specifically and quickly adapted to constantly changing processing situations. In the near future, lasers will be able to polish, coat or structure surfaces up to ten times faster than before thanks to this tuning.
EHLA Research Team Wins Renowned Berthold Leibinger Innovationspreis 2018
The research team of the Fraunhofer Institute for Laser Technology ILT and the Chair of Digital Additive Production DAP of RWTH Aachen University will be honored with the Berthold Leibinger Innovationspreis 2018 for their development of the “Extreme High-Speed Laser Material Deposition” (EHLA). This process can be used to coat, repair or additively manufacture components in a particularly economical and environmentally friendly way. On September 21, the Aachen scientists will receive the first prize of the laser innovation prize awarded by the private foundation Berthold Leibinger Stiftung in Ditzingen, Germany, every other year since 2000 for outstanding research and development on the application or generation of laser light.
3D-Printing: Support structures to prevent vibrations in post-processing operations for thin-walled parts
One of the main features of additive manufacturing processes such as 3D-printing is that the complexity of the component shapes it produces, is virtually unlimited. However, high surface quality in metallic components can frequently be achieved only via milling or grinding finishing operations. Milling operations conducted on thin-walled parts in particular often cause vibrations which impact negatively on part accuracy and on machining time. The Fraunhofer Institute for Production Technology IPT and the Fraunhofer Institute for Laser Technology ILT in Aachen will be presenting special-purpose support structures which can eliminate these vibrations in post-processing operations at Farnborough International Airshow from 16 – 22 July 2018.
