Additive manufacturing, also described as 3D printing, is opening up new pathways to production. While many of these are dead ends as economics and logistics limit some of the hoped-for applications, others offer the potential to be game changers in the manufacturing arena.

Printed body parts are taking shape in laboratories, but printed industrial parts may not always fit the bill. Issues such as reliability, integrity and longevity must be determined on a case-by-case basis as custom parts are devised and built.

The mid-1970s TV series "The Six Million Dollar Man" is no longer a mere futuristic dream. While today's injured warfighters aren't able to run 60 miles an hour or possess superhuman strength like fictional character Steve Austin, they are still achieving amazing results through robotics and prosthetics. And now, many are returning to service in fully functional mode. Technology Editor George I. Seffers looks at U.S. Army efforts to make soldiers physically whole again in his article, "Robotics Research Gives Life to Artificial Limbs," in this issue of SIGNAL Magazine.
