About the W3+ Fair

Top Ideas For Key Technologies

High-tech Meets Users

The cross-industry concept makes the W3+ Fair so unique: researchers, developers and producers from the four key technologies network with each other and meet top international experts from important application areas such as MedTech, Life Science, Automotive, Aerospace, Consumer Electronics and Tools & Machinery. Innovative strength meets concrete demand. With success: joint visions and new partnerships for the technological requirements of tomorrow are created around the W3+ Fair.

The pace of technological innovation keeps increasing. This applies to all sectors. The W3+ Fair – THE networking and new business event for the optics, photonics, electronics and mechanics sectors – meets this trend head-on.

Interdisciplinary Platform

Developers and users network face-to-face across disciplines and countries, promoting new technologies and solutions.
Big players as well as up-and-coming companies successfully get themselves ready for the future with new contacts and partners.
The W3+ Fair takes place at two top technology locations. Where local companies celebrate global successes: in the optics region of Wetzlar in Hesse and in Jena in Thuringia, the fair uses the charisma of the economically strong high-tech industry. The W3+ Fair is organised by the Hamburg trade fair organiser FLEET Events.
