As struts provide structural support for vehicle suspension, the mechanical properties of this fully WAAM-printed aluminium part are essential to bear the intense forces critical to vehicle handling, control and stability. Next to the optimised design, lower component weight, enhanced production efficiency and functional performance, using WAAM results in lower energy requirements and improved material usage.
Compared to other 3D metal printing technologies, WAAM has proven suitable for medium to larger structural components as these components can now be manufactured faster.
“It’s impressive to see how WAAM technology has developed from research to become a flexible tool for not only test components but also series production components. The use of generative design methods enables us to make full use of design freedom and thus the potential of the technology. That was unthinkable just a few years ago,” said Karol Virsik, Head of BMW Group Vehicle Research.
