A BRILLIANT FUTURE FOR ADDITIVE A dditive manufacturing (AM) continues to impact the materials science landscape. Relativity Space recently announced the ability to 3D print a rocket in days instead of years. The process uses significantly fewer parts while optimizing quality and time performance. They’re do- ing something right. But we can also insert other company names and applications and discover further astounding results. AM is a game changer across the board. Yet, more is being asked of the technology every day. A recent survey conducted by Shapeways (a digital manufacturing plat- form provider) paints a picture of the state of 3D printing in the U.S. More than 300 mid-sized manufacturers, representing a swath of the automotive, aero- space, robotics, medical device, and industrial sectors, were polled. In rearview mirror mode, the survey shows that over the past three years, the top five cus- tomer expectation changes have included: higher demand for quality (53%); in- creased requests for sustainable solutions (47%); more frequent design changes (45%); desire for higher-level customization (43%); and continued cost reduc- tions (40%). Looking forward, 84% expect the technology to continue increasing their revenues while decreasing costs. The envelope is being pushed. In response to that push and moving beyond traditional AM sectors, the biomedical industry is making advances of its own. In this penultimate issue of AM&P for 2021, Pete Ledesma of the University of the Philippines brings us up to date on how hydrogels can be used in 3D bioprinting to seal leaks in liver and lung tissue. Applications for additive manufacturing are seemingly endless. In fact, our lead story indicates that your next piece of sports equipment may be made of additively manufactured metallic glasses. If these articles whet your appetite for more AM research, check out the pa- pers from our Journal of Materials Engineering and Performance selected for you by ASM Past President William Frazier, FASM, on page 32 and learn how to get involved with other AM efforts within the Society. Also in this issue, and winning this year’s ASM Engineering Materials Achievement Award, QuesTek Innovations provides an update on their novel high-performance carburizable steel. Their Ferrium C64 steel was birthed via integrated computational materials engineering (ICME). Primary applications include lighter-weight transmission gears with increased power density. But the Ferrium C64 story does not stop there. The alloy has now headed into the AM space with the company’s engineers producing C64 powders that will maintain the superior performance of AM parts. QuesTek also participated in a popular Additive Manufacturing Panel at IMAT, moderated by ASM Vice President David Williams, FASM. Attendees at IMAT and Heat Treat also enjoyed top-notch keynotes from materials engineering leaders at Tesla and Ford describing how electric vehicle development is break- ing all the standard molds and forcing new ways of thinking. In Tesla’s case, they are moving beyond typical additive to envision new casting techniques. Hint: Imagine one giant cast to replace numerous smaller components. After these thought-provoking St. Louis sessions, attendees were then dou- bly rewarded with views of the magnificent Clydesdales while sipping Anheuser- Busch brews during the networking social. Nice way to savor the old world while contemplating the brilliant future. joanne.miller@asminternational.org
