4 Welcome to our IMAT show issue with a focus on additive manufacturing (AM). The technology around AM continues tomature and find new applications. And new solutions are being discovered every day to overcome previous limitations. One of the main challenges with AM is production time. A standard fused deposition modeling printer averages 100 mm/hour. And we are all familiar with the slow, meditative cadence of a typical AM build. Yet, if printing is accelerated, vibrations occur, leading to poor quality and even misshapen components. Entire batches may need to be scrapped. To address this problem, Dr. Chinedum Okwudire, a University of Michigan (U-M) professor and his students launched new software that doubles the typical 3D printing speed. Their software, called FBS for Filtered B Splines, performs this veritable magic by compensating for the usual vibrations caused by acceleration. “Say you want a 3D printer to travel straight, but due to vibration, the motion travels upward. The FBS algorithm tricks themachine by telling it to follow a path downward, and when it tries to follow that path, it travels straight,” Okwudire explains. Another development in the AM sector addresses previous limitations regarding component size. Our lead article shows how directed energy deposition now allows for extremely large structures to be built more rapidly and with minimal machining. The AM space keeps evolving and expanding. What other developments are on the horizon? To learn about additional AM research, attend IMAT 2022, which will feature three days of programming on additive along with many other materials topics. In line with the conference theme of the Circular Materials Economy, Dr. Mrityunjay Singh, FASM, will deliver a special lecture on Tuesday morning covering how AM is disrupting global supply chains and enabling sustainable materials development. See our IMAT Show Preview on page 27 for details of this September conference being held in New Orleans. To provide more options for our attendees, the event is co-located with the Thermal Spray & Surface Engineering (TSSE) Forum and Exposition. More information on TSSE programming can be found on page 34. An exciting highlight of ASM’s annual event this year is the new Fellows Induction Ceremony on Monday evening, September 12. There you can meet three years’ worth of the newest ASM Fellows, fromClasses 2020, 2021, and 2022. All ASM members and guests are welcome. This unique, first-time event is in addition to the traditional ASM Awards Dinner. We hope to see many of you at both events. Like the U-M students who are making a name for themselves with their new software launch, our students and emerging professionals have research of their own to share in New Orleans. Presentation and program opportunities for both sets of these next-gen engineers will be available at IMAT. The Emerging Professionals Committee describes their lineup in the ASM News section of this issue. We look to them—as their careers unfold and mature—to devise the next set of novel solutions to AM and many other materials challenges. joanne.miller@asminternational.org A D V A N C E D M A T E R I A L S & P R O C E S S E S | J U L Y / A U G U S T 2 0 2 2 ASM International 9639 Kinsman Road, Materials Park, OH 44073 Tel: 440.338.5151 • Fax: 440.338.4634 Joanne Miller, Editor joanne.miller@asminternational.org Victoria Burt, Managing Editor vicki.burt@asminternational.org Frances Richards and Corinne Richards Contributing Editors Jan Nejedlik, Layout and Design Allison Freeman, Production Manager allie.freeman@asminternational.org Press Release Editor magazines@asminternational.org EDITORIAL COMMITTEE Adam Farrow, Chair, Los Alamos National Lab John Shingledecker, Vice Chair, EPRI Somuri Prasad, Past Chair, Sandia National Lab Beth Armstrong, Oak Ridge National Lab Margaret Flury, Medtronic Surojit Gupta, University of North Dakota Nia Harrison, Ford Motor Company Michael Hoerner, KnightHawk Engineering Hideyuki Kanematsu, Suzuka National College of Technology Ibrahim Karaman, Texas A&M University Ricardo Komai, Tesla Scott Olig, U.S. Naval Research Lab Amit Pandey, Lockheed Martin Space Satyam Sahay, John Deere Technology Center India Kumar Sridharan, University of Wisconsin Jean-Paul Vega, Siemens Energy Vasisht Venkatesh, Pratt & Whitney ASMBOARDOF TRUSTEES Judith A.
