Getting Past the Hype About 3-D Printing

Although additive manufacturing techniques hold great promise, near-term expectations for them are overoptimistic.

The hope for additive manufacturing is that it will revolutionize manufacturing.1 Although additive manufacturing — also known as 3-D printing — was developed back in the 1980s, it has garnered increased attention in recent years as managers look for ways to improve efficiency and reduce production costs. Managers hope that much the way GE’s new printed nozzle for jet engines has reduced the need for expensive materials and energy,2 3-D-printed parts will cut lead times and make supply chains more efficient in a wide range of settings.3

Despite the potential of additive manufacturing, we believe that near-term expectations for it are overblown. We base this conclusion on our research, which included 80 interviews as well as extensive study of the literature on the history of materials and process technologies, industry meetings, and factory visits.4 (See “About the Research.”)

Thank you for writing this. 30 years after invention, we are _still_ in the early stages for serious applications of this technology. Printing charm bracelets is one thing; making parts that must hold up over years is something very different. Your lovely article,  "When risks cannot be seen: Regulating uncertainty in emerging technologies"  http://dx.doi.org/10.1016/j.respol.2017.05.010 discusses some of this in more depth. 

What people seem to hope is that if a computer file can describe the external shape of a complex object, that will be sufficient to fabricate it. Demonstration parts were done this way, but practical/inexpensive parts need complex internal designs to reduce weight, cost, and fabrication time. Additional part requirements, such as movement, add additional design complexity. At least for now, this requires design expertise. In your opinion, to what extent will this problem ever be reducible to design rules? What about full automation for non-trivial problems?
