U nless you’ve been enjoying an extended off-the-grid sabbatical, you already know that metal additive manufacturing (AM) is continuing to post double-digit growth year after year. Everymaterials engineeringmagazine, website, and technical conference is addressing this topic— sometimes at the expense of other less glamorous yet incred- ibly stalwart manufacturing processes. Nevertheless, recent statistics documenting the steep and steady growth of 3D printing are astounding. Consider a few numbers from the Wohlers Report 2019, the 24th consecutive year of this key survey of the global AM industry: Revenue from metals for AM grew 41.9% in 2018 to roughly $260.2 million, up from $183.4 million in 2017, $126.8million in 2016, and $88.1million in 2015. Amajor trend noted during 2018 was increased powder production capacity among many AMmaterials suppliers. Although capacity grew across a wide spectrum of alloy systems, titanium alloy powder may have achieved its highest percentage growth rate to date, according to the report. In addition, aluminum powder is also attracting more attention. With regard toapplications, aero- space is a prime example of both growth and potential for metal AM. For instance, GE Aviation is a well- known success story, with the com- pany producing metal AM fuel noz- zles for its LEAP engine. As of October 2018, more than 30,000 fuel nozzles had been manufactured us- ing AM; by 2020, GE expects to build more than 120,000 parts by AM for the LEAP and other aircraft engines, according to Wohlers. Airbus is another example. The company has manufac- tured—and put into service—over 100,000 plastic brackets, clips, and other devices for securing cables, wires, and hoses, in addition to producing metal AM parts. With all of this growth, AM&P will continue to cover additive manufactur- ing in every single issue, as we have done for the past few years. New this year are two special editions dedicated to metal AM—our July/August and October issues. Tell us what you think and what you would like to learn more about. We know that concerns about parts qualification, standards, and materials charac- terization are critical, so we will be covering these topics as well. (See page 22 for an informative article on AM powder testing.) One final note: This is my last column for AM&P. Farewell, hydrogen embrit- tlement. See you later, austenite to martensite. I am leaving ASM to focus on my technical and scientific writing business full-time, where I will continue to edit and write technical articles, white papers, case studies, press releases, science blogs, and more. Please find me on LinkedIn to say hello. I’ll miss the camara- derie among ASM’s members and chapters that I have thoroughly enjoyed over the past six-and-a-half years, including the letters I’ve received from many of you. I now leave the magazine in the very capable hands of Joanne Miller, my esteemed colleague and friend. I wish you all the very best and I hope our paths will cross again in the future.
