A funny thing happened on the way to writing this blog—Additive Manufacturing (AM) has grown up. Now, some may rightly say that AM has been around for decades. And it has. But there can be little doubt that the reach and scope of AM, or 3D printing, now touches virtually every aspect of industrial and, indeed, human activity. Certainly, Deloitte’s 3D Opportunity collection of thought leadership bears this out in the vast scope and depth of its coverage. And, of course, one can also point to any number of widely available metrics that makes clear AM’s remarkable strides—from number of patents to AM system revenues to how common the term “additive manufacturing” now appears in Google searches compared to just a few years ago.
