Enabling Technologies

Future technologies on the way onto the world market – and into our everyday lives: the W3+ Fair is Europe's leading platform for high-tech innovations in the optics, photonics, electronics and mechanics sectors. This networking event brings together international expert knowledge and a high concentration of expertise at top technology locations close to major key players and hidden champions.
