Important Events in AM

April 22, 2018

Last week, I attended the 20th Annual FIRPA Conference in Espoo, Finland, which is about 20 km (12 miles) from Helsinki. The event included some excellent presentations, including one from Jonas Eriksson of Siemens Industrial Turbomachinery AB. Eriksson discussed the production of parts by additive manufacturing for land-based gas turbine engines. To date, the company has redesigned many parts for metal AM and used the technology to produce more than 1,000 burner tips. The use of AM has resulted in a time reduction from 26 weeks to just three. As many as 60 people are now focused on AM at the company, with a goal of making metal AM as simple as 2D printing on paper.

Another very interesting presentation was given by Jyrki Saarinen of the University of Eastern Finland. His group worked closely with Dutch company Luxexcel to produce an AM machine with 1,000 inkjet nozzles for the printing of optical lenses in PMMA. The surface finish of the printed lenses is <2 nm RMS (less than 2 billionths of a meter), so no post-processing is required. The machine is capable of producing 40 lenses per hour, each measuring 10 mm in diameter x 2.5 mm in height, so the process is relatively fast.

I also had the privilege of visiting two world-class companies in Finland. The first was KONE, an $11 billion manufacturer of elevators, escalators, exterior revolving doors, and security entrances for commercial buildings. The company and its products are impressive. I also visited UPM, a $12.3 billion company with a strong position in paper, pulp, plywood, composites, and bio products. The company recently entered the AM industry by introducing a material extrusion filament product consisting of cellulose fiber and PLA.

Last week’s trip to Finland could not have gone better, thanks to the fine people that organized the meetings and very successful 20th annual conference. This week, the focus is on RAPID + TCT 2018, which begins tomorrow and goes through Thursday in Fort Worth, Texas. This event marks the 26th annual conference and exposition, and I’m proud to say that I have not missed a single one of them. Attendance has grown by ~2.3 times over the past four years and exhibit space has grown by ~4.5 times over the same period. If you are interested in attending one of the very best events in all things additive manufacturing, 3D printing, and 3D scanning, go to Fort Worth this week. You will not regret it.

AM at NATO?

Obstacles to adopting additive manufacturing (AM) in any large organization are well known. The North Atlantic Treaty Organization (NATO) faces additional challenges due to the diversity of its 29-nation membership. Each has its own policies and procedures and is at a different stage of adoption.

In 2016, the NATO Allied Command Transformation unit formed an AM Community of Interest (COI) consisting of leading voices and technical experts across the alliance. Its purpose is to coordinate AM efforts among member nations and share progress. The COI is exploring potential AM use cases and examining relevant standards. It is also reviewing necessary data security measures and interoperability within NATO’s environment.

The COI has swiftly addressed NATO’s issues. First, COI members participated in the U.S. Department of Defense-sponsored AM Business Process Wargame, which explored complex business practices necessary for AM use in the military. The COI also published a report detailing current standards applicable to AM.

The COI and its members maintain high-tempo participation in AM events. Drawing on experience from the Norwegian Ministry of Defense (MOD) and the U.S. Marine Corps, the COI is exploring expeditionary logistics applications. The Marine Corps demonstrated its “ExFab,” a self-contained transportable 3D printing facility, to NATO at its meeting in October 2017. This year, the Norwegian MOD will demonstrate a similar capability.

COI members will participate in NATO meetings in Germany, Italy, and the U.S., as well as NATO exercises in Norway and Poland. A study will include member nation AM activities and a roadmap proposing the way forward for AM at NATO. The COI will study blockchain as a potential security enhancement, as well as lessons from the experiences of Estonia, the most connected nation in the world. This month, the COI will be represented at RAPID + TCT 2018 in Fort Worth, Texas.
