AM BRINGS ON INNOVATIONS Amazing innovations are occurring every day in the world of materials. Additive manufacturing (AM) processes can be found at the core of many of those advances. Among its benefits over traditional manufacturing methods are design flexibility, rapid prototyping, increased customization, fewer defects, lower cost, and reduced waste. And let’s not forget the wow factor. Recently, a team at the University of Glasgow created the world’s first 3D-printed microscope in under three hours. The microscope has a single lens with a 2.9× magnification and was made for less than 50 dollars. For more clever applications of AM, turn to our 3D PrintShop page and learn about a miniature 3D printer that can fit into the palm of your hand. In another story, you can read about how 3D-printed bendable concrete could revolutionize the construction industry. Other impressive applications are being employed to solve problems in space. NASA is conducting experiments on the International Space Station to examine the behavior of colloids or “soft matter” in the microgravity environment. Knowledge gathered from those studies will help astronauts build or repair equipment and materials in space, exactly when the need arises. Bringing the conversation back to earth for some practical uses here, this issue of AM&P offers several articles with scientific results and pragmatic tips from various AM practitioners. Holden Hyer from Oak Ridge National Laboratory (ORNL) provides insights into the use of laser powder bed fusion for rapid qualification of new materials in the nuclear sector. By pairing two microstructural characterization methods, the quality and long-term performance of nickel-base AM components in their study can be accurately evaluated. For more from ORNL, turn to our Research Tracks page to learn about a partnership with the DOE’s Idaho National Laboratory that is improving the inspection process of additively manufactured nuclear components. Their next challenge is to use their specialized technology to conduct quality checks on nuclear fuel cells. Next, we move from the national labs to a commercial lab. With Dana Drake as our tour guide, we get a glimpse into the workings of an AM-focused metallurgical lab at EOS in Texas. Her article describes best practices the team follows in conducting metallographic inspections of AM powders. And finally, checking in with industry, the R&D folks at Continuum Powders share an article that addresses how powder operations could be made “green” through a single-step plasma-assisted atomization process. Their method allows for more scrap alloy to be collected and repurposed for future AM projects. Whether a specific AM application is backed by strong scientific data with practical uses or just has the wow factor, AM is here to stay. And we can count on it to bring on more innovations. joanne.miller@asminternational.org 3D-printed microscope. Courtesy of University of Strathclyde, Glasgow.
