+ HLEM High Level Expert Meeting 2023

W3+ Fair Wetzlar
29 + 30 March 2023


A cradle of visionary ideas

Booming high-tech region in Hesse

It’s not only the world-famous Leica camera that was invented here – the W3+ Fair is also “Made in Wetzlar”. The industrial network Wetzlar Network launched the trade fair in 2014 in conjunction with FLEET Events – and found the ideal location in its home city in the state of Hesse. Around the leading centre of the optics industry there are more world market leaders than almost anywhere else. At the W3+ Fair, you can easily talk to the global players face-to-face! Learn new things, expand your network and enjoy two trade fair days, on 29 and 30 March 2023, devoted to future technologies in the fields of optics, photonics, electronics and mechanics.

NEW: The HLEM 2023 (High Level Expert Meeting) will be held  parallel with W3+Fair.

Review W3+ Fair Wetzlar 2022

Successful meeting of future industries at the W3+ Fair 2022 in the optics location Wetzlar/ Germany

A total of about 125 exhibitors as well as partners and sponsors were welcomed together with more than 1500 trade visitors at the international trade fair W3+ Fair in Wetzlar/ Germany on July 6 and 7, 2022. The new accompanying high-tech congress en-tech.talks was very well received.


Networking with technology leaders

The Wetzlar region relies on the strong impulses of the successful fair: In addition to the Wetzlar Network, the international photonics consortium EPIC also supports the W3+ Fair – together with regional companies and partners from science and politics. A strong network from which you benefit! Thanks to the cross-industry concept, the W3+ Fair is the only trade fair that brings together cutting-edge knowledge from four key technologies in one place. Be inspired by the leading minds of the high-tech industry, take advantage of the numerous opportunities for talks and contacts and experience the power of networking live!
