Has 3D printing (3DP) finally come of age? It’s become clear that the technology, also known as additive manufacturing, is crossing from a period of hype and experimentation into one of rapid maturation. 3D-printed parts and products are quickly making their way into end products—from a printed car to athletic shoes to a printed NASA rocket engine. Industrial 3D printers, once almost exclusively used for prototyping, are now, on some of America’s factory floors, being rolled out on production lines. Manufacturers of all stripes are building 3DP programs and are likely to continue to expand those programs as advancements in 3D printers, software and printing materials (or “inks”) make adoption easier and more cost-effective.
