Where Is Additive Manufacturing Headed?

When the Trends editors first started talking about additive manufacturing a few years ago, it was both exotic and unusual.  There was a lot of buzz about potential, but most of the real-world applications weren't really ready for primetime.  However, technical capabilities and user sophistication have advanced at a rapidly accelerating pace.  What have we learned?  Is additive manufacturing really living up to its promise?  Where are the biggest payoffs likely to emerge?  We’ll answer these questions and more.
