The gradual electrification of the automotive industry is impacting many sectors, but perhaps nowhere are the effects
being felt as strongly as in the foundry industry. At the moment, more than half of the metal components cast in Germany
are built into road vehicles, but many of them will no longer be needed in future electric vehicles. Of course, e-mobility
does present new business opportunities in this regard. However: »There won’t be enough alternative business to go
around in the foundry industry in the years ahead,« predicts Simon Geib, head of project management and business
development at Gienanth Group GmbH. This is why Gienanth, which boasts a centuries-long history in the aptly named
town of Eisenberg (western Germany), has already adapted its strategy to the new challenges ahead – and could thus be
blazing a trail for its entire industry. The 3D printing of sand molds plays a key role in its approach.

It is as if additive manufacturing was tailormade for the satellite construction industry, which is all about very small
quantities, complex designs, and a quest to reduce weight: all demands that suit additive manufacturing to a T. No won-
der, then, that satellites containing 3D-printed components have already been orbiting the earth for several years now. ­
In this second part of our »AM in the Space Industry« series, we look behind the scenes to find out how widespread AM
is in satellite construction at the moment, what market potential it has, what trends are driving the industry, and what
challenges satellite manufacturers and their service providers still face.
