This collaboration between ECAL and the swiss brand Victorinox aimed to identify new ways to use stainless steel in the watch industry.

I decided to explore a process called cold spraying. It is an additive manufacturing process, which consist in spraying metal powder at supersonic speed on a substrate. At such speed, the particule plastically deforms and stays bonded to the substrate, avoiding the need to sinter the piece afterwords.

The idea for Victorinox was to use the cold spray to manufacture the case of a watch: it would drastically reduce the machining operations and also save a lot of material by building a rough outline around a tube. The tube would then be cut to size to provide the case.
