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.
