3D Days - March 18, 19, and 20, 2026
Exclusive Open House at the Citadelle des Savoir-Faire.
3D Days
The 3D Days are the three major days of the year during which the Citadelle des Savoir-Faire and all the companies based there open their doors to the public.
This event offers an exclusive behind-the-scenes access to areas that are usually closed, live demonstrations—some of which are only presented once a year—and innovations unveiled for the first time by each entity.
It’s the perfect time to discover all our technologies, meet our teams, and participate in the key moments that define our annual rhythm.
