Voices about the fair

“W3+ FAIR has developed into a ‘standard trade fair’ in the optics sector within a short period of time. As a manufacturer of precision optics, MPO can hardly afford not to be represented at this efficiently designed trade fair with a highly qualified range of visitors.”
“For us, the W3+ FAIR is a must. We have been there from the beginning and meet many important contacts of the German optics cluster here in two days. Mass is not important to us, we want class – so we’re in the right place here.”
“The small but fine trade fair for precision technology.”
“The fair brought me many new and good contacts with renowned companies. It is enormously important for a start-up company like mine to show my 3D printing services to the professional audience.”
“W3+ is a good fair that closes the gap to Optatec and Laser.”
“The exhibitors confirm the quality of the contacts for networking, partnerships and new business. This is exactly what W3+ FAIR stands for.”
