machine sales and 67% came from printed parts and other digital manufacturing services.
ExOne is looking to further expand its production services under its ExCast division, which aims to supply complex finished casting parts for prototyping and short-run production on a rapid delivery platform to global industrial customers. That proposition includes everything from mold design and solidification analysis to heat treating, machining, coating and final inspection. ExOne seeks to build out that value streatm largely through acquisition.
“The opportunities to redesign are huge. But they can’t go back once they’ve gone through the door. It’s a one way door.”
S. Kent Rockwell, chairman and CEO, said interest con- tinues to grow in the company’s binder jetting technology, especially as new materials with higher density potential are brought online. “We believe that nickel-based Inconel alloy 625, recently introduced as our first single metal alloy providing more than 99% density, expands our addressable market, expecially in the aerospace, chemical and energy markets,” he said. “To create additional opportunities for growth, we continue to work with customers to develop new metal material sets. And, with our expanded production capacity currently underway, we’ll be ready to respond as this market continues to grow.” During his recent meeting with investors and the media, Burns discussed the potential of additive manufacturing in the industrial arena, as well as its challenges. For example, once a customer decides to use additive manufacturing for a part, there are many improvements to the part that can be made to reduce weight or reduce cost without affecting performance. But once those changes are made, a company is now com- mitted to building that part through additive manufacturing as there is often no way to make that altered part with traditional manufacturing processes. That change can be quite a com- mitment for some original equipment manufacturers, and Burns acknowledged that fact may be slowing down adoption in some quarters.
“The opportunities to redesign are huge,” Burns said. “But they can’t go back once they’ve gone through the door. It’s a one way door.”
Once they’ve gone through, however, many manufacturers are greeted by significant benefits in terms of design improve-

ments that reduce waste, save money and may substantially improve an approach to a part or its function altogether. For example, ExOne now prints sand cores for impellers without a core box, which allows a customer to deliver impeller cast- ing in under two months—a substantial time savings when standard molds can typically take months to machine. ExOne says it can create complex molds and cores with accuracies of ± 0.011" or ± 0.3 mm. ME
