JULY 2018 Additive Manufacturing 2 30 Toward Tailored Materials A conversation with Carpenter Technology suggests that AM is moving past existing materials toward specialized and eventually fully custom options. By Stephanie Hendrixson 34 Solving a Materials Challenge in Soft Robotics A team from the University of Minnesota and the Army Research Lab has developed processes for fully 3D printing soft dielectric elastomer actuators without postprocessing steps. By Brent Donaldson 36 Roush Makes Fast Things, But Now It's Making Things Fast A 3D-printed cylinder head investigation reveals the possibilities of additive manufacturing. By Christina Fuges 38 Powder Application Plus Five-Axis Machining Hermle integrated its MPA technology, a process where metal powder is applied by kinetic compacting to build completely sealed materials, into a five-axis machining center to create parts with highly complex inner geometries. By Barbara Schulz 12 Taking Shape • AM Will Advance Plastics, But Open Parameters Increasingly Valuable • In Metal AM, One Device Inspects Both Parts and Powder • Printing End-Use Parts from High-Performance Ceramics • One-Piece Robot Gripper Actuated by Shop Air IN EVERY ISSUE Something to Add 06 News 08 On Display: IMTS 42 Ad Index 55 Check This Out 56 ABOUT THE COVER: The cover image is a close-up of CarTech Puris 5+ powder, a titanium alloy developed specifically for AM. The material's low oxygen content means it can be reused more times than standard Grade 5 titanium, while also reducing risk in the final part. Read how it was developed in the story beginning on page 30.
