Our client, CFL (National Association of Luxembourg Railways) wanted to replace the broken cabinet locks of their locomotives.

These locks were not in production anymore. We redesigned the lock and with the advantages of 3D printing technology and more specific SLM (selective laser melting) of aluminium powder, we managed to redesign and produce a small series of the cabinet lock.

Without the advantages of 3D printing, CFL would have been forced to replace the entire cabinet, which means they would have spent more time and money to get the same result.
