T here is always something thrilling about stories of pio- neers and explorers. Their adventures require bravery and smarts. They hazard forward into the unknown with an eagerness for whatever discovery awaits them. In this issue—our second edition dedicated to additive manufactur- ing (AM) this year—our authors share their trailblazing tales in the form of research, data, and results. And their discoveries are every bit as compelling. First up and ever in the forefront of AM, GE Research Center describes their unique machine learning approach to qualify new alloys for AM in their article “A Physics-Informed Data-Driven Approach to Additive Manufacturing Parameter Optimization.” Their intelligent design analysis of computer experiments allows for higher confidence with fewer trials, resulting in faster-to-market alloys. Across the pond, staff at the Federal Institute for Materials Research and Testing (BAM) in Berlin are taking the lead on addressing the challenges of AM in safety-critical applications. The article “Additive Manufacturing at the BAM: Focus on Safety” outlines their recommendations for both materials characteri- zation and the standardization of AM processes to improve the safety landscape. In addition to our usual coverage of metal AM, in this issue we take a peek into the world of ceramic AM. After metals and plastics, ceramics is the next fron- tier in 3D printing. Here we introduce you to some of its pioneers. In “3D Printing of Ceramics,” Robocasting Enterprises reviews the most prevalent techniques in the field and how each was first developed. Their own 3D printing method has accomplished large production runs—a rare feat within ceramic AM. A novel technology for ceramic AM—nanoparticles jetted from printing heads without the use of lasers—is presented by XJet Ltd. in “Additive Manufac- turing in Technical Ceramics.” They cite market research that predicts growth in ceramic AM from $174 million in 2017 to $544 million in 2022, and catapulting to $3.1 billion by 2027. That’s a lot of nano material! In April 2018, XJet, headquartered in Is- rael, selected the Youngstown Business Incu- bator (YBI) in Ohio as the site of the first U.S. installation of their Carmel 1400 AM System. At the unveiling, I snapped this shot of the XJet team during a patio reception at the home of Youngstown State University president Jim Tressel. With football many years and yards behind him, Tressel has become a champion of AM with YBI and America Makes now practically in his backyard. We’ve been innovating a bit ourselves, and are pleased to announce the inaugural edition of the SMST NewsWire in this issue. This biannual supplement to AM&P is a product of our affiliate society, the International Organization on Shape Memory and Superelastic Technologies (SMST). Speaking of pioneers, the founders of SMST—Tom Duerig, Alan Pelton, and Darel Hodgson—formed the Society in 1992 to provide education on shape memory alloys and promote their use in new applications. Learn more by read- ing the editorial from SMST president Othmane Benafan on page 33. The articles in this first SMST NewsWire from NASA Glenn Research Center and Fort Wayne Metals provide a glimpse into the unique capabilities of Nitinol (nickel-titanium) and its derivatives. Grab a cup of coffee and prepare to be inspired by these materials science groundbreakers. joanne.miller@asminternational.org MATERIALS PIONEERS XJet team in Youngstown
