I attended last week’s formnext, powered by TCT, in Frankfurt, Germany. The four-day event, involving an international exhibition and conference, was outstanding, especially given that it was the second year. Most major companies in additive manufacturing and 3D printing were present, and many had very large and impressive exhibits. One could easily make the case that it was the most elaborate and striking display of AM products and services ever.
As with most events, the people in attendance were as important as anything else. Organizations around the world sent their best and most informed employees. This is especially important for visitors wanting to schedule meetings and have discussions about AM and where it is headed. If the schedules of others were anything like mine—and I’m sure many were—they had little spare time through the week because of all that formnext had to offer.
If the event had a theme, it was metal AM. Additive Industries, Arcam, Concept Laser, EOS, ReaLizer, Renishaw, 3D Systems, and SLM Solutions had large displays with machines and parts. Companies relatively new to metal AM that showed their machines were AddUp (a collaboration between Michelin and Fives), Farsoon, OR Laser, Sentrol, and Sisma. Fraunhofer ILT displayed a small and relatively low-cost metal AM machine that may be commercialized at some point.
Some of the mature companies showed automated metal powder removal and handling capabilities and concepts. As their customers ramp up for production quantities, this automation will become important. Absent was the automation of most other downstream operations, such as thermal stress relief (with the exception of Additive Industries), hot isostatic pressing, and the removal of parts from the build plate. Also absent was automating the removal of supports/anchors from the parts, CNC machining, and surface treatment.
Regardless of your interest in AM, formnext had something for everyone and was the place to be last week. One exhibition hall included a large and impressive concentration of technology and know-how. It was completely filled, so Messe Frankfurt and TCT employees are planning to expand into a second hall for the 2017 event, which is set for November 14-17. The four days of conference sessions were also very good and well attended. I only wish I could have attended more of them. Maybe next year.
