W elcome to 2016! We hope you have all enjoyed a restful holiday season and that your new year is off to a good start. As a word watcher, one of my favorite things is to see what the dictionary companies announce as their “Word of the Year.” For 2015, Merriam- Webster declared the suffix “ism” as its 2015 pick. Words such as socialism, fascism, racism, and terrorism received the highest traffic spikes on the company’s website in cor- relation with the year’s biggest news stories. It was a heavy year indeed. Looking ahead, it would be nice if we could go from “-ism” to “-ion,” as in words like education, imagination, innovation, inspira- tion, and another recent favorite—Orion. Speaking of Orion, I had the privilege of attending a media event at NASA Glenn Research Center’s Plum Brook Station in Sandusky, Ohio, in late Novem- ber. Over the next few months, the facility will run experiments on the newly arrived, full-size test version of Orion’s service module, provided by the Euro- pean Space Agency (ESA). The module will provide in-space propulsion, as well as power, air, and water for astronauts. Test engineers will use a large vibration table and acoustic chamber to replicate the shaking and noise the module will experience as it enters space. A solar array deployment test and pyrotechnics will also be used to simulate shock loads the module will face during separation from the Space Launch System rocket. After listening to NASA, ESA, Airbus, and 2016: FROM ISM TO ION

Lockheed Martin dignitaries speak and tour- ing the Plum Brook facility, my colleague and I had the same takeaway. With all of the dark- ness and destruction taking place around the globe due to various “isms,” it was truly in- spiring to learn about international teams of people from different companies and coun- tries working together to build something in the name of science and humanity. You’ll notice that, coincidentally, Ori- on’s Exploration Flight Test I is this month’s cover image. One of the interesting aspects of Orion is its use of several noncritical 3D-printed components. Our story covers ad- ditively manufactured (AM) spacecraft vents, courtesy of Lockheed Martin. At the Plum Brook event, I had the chance to speak with

Test version of Orion’s service module at NASA’s PlumBrook Station.

Mike Hawes, Lockheed’s programmanager for Orion. He emphasized the need to develop non-flight-critical AM parts for space applications to help pave the way for more complex, flight-certified part development. In other AM news, be sure to check out our latest department page— 3D PrintShop. With so much happening these days, and covering the topic in nearly every issue, we decided to dedicate our final magazine page to high- lighting a few of the most newsworthy AM developments. If you’re working on anything interesting, we’d love to hear about it. We wish all of you a happy and productive 2016!
