About W3+ Fair

Top ideas for key technologies

High-tech technologies meet user industries

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 for the high-tech industry

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 in Europe’s German-speaking region. Where local companies celebrate global success: in the optics region of Wetzlar in the German state of Hesse and at the place where four countries meet in the Rhine Valley, the trade fairs harness the pulling power of economically strong high-tech regions. The W3+ Fair is organised by the Hamburg trade fair organiser FLEET Events.
