The first annual North American DIFFSYS User’s Group Meeting was held at the Best Western hotel in Keene, NH on 4 May, 2017. There was a very good turn out with representatives from BAE, Clear Align, General Dynamics, ISP Optics, Janos, Rochester Precision Optics, Syntec, and Wilcox Industries all participating. We were happy to also have Alan Edwards, the founder of DIFFSYS in attendance. The meeting was a chance for DIFFSYS users to share their experiences and collaborate with other expert users. If you are interested in joining the user’s group please contact Kirk Rogers or Cathi Giard.
