WAAM vs. Die-Casting in the Automotive Industry?

Wire Arc Additive Manufacturing (WAAM) allows for lighter and stiffer components compared to traditional die-casting methods. This conclusion is reached by an automaker that compared the processes in trials using a strut brace as an example.

Manufacturing processes can complement each other

Various additive manufacturing processes do not necessarily compete with each other but should be seen as complementary. For high detail resolution, laser beam melting will continue to offer advantages over the WAAM process. In terms of the possible size of the component and the deposition rate, Wire Arc Additive Manufacturing seems superior, concludes the manufacturer.

In perspective, the use of components in series vehicles of the BMW Group is envisaged. It is conceivable to produce individual parts with this process directly on the assembly line and manufacture different parts through software changes alone, without new tools. Additionally, sustainability can be further increased by using more recycled metals.
