Getting past the hype about 3-D printing

Abstract

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\u3cbr/\u3e\u3cbr/\u3eDespite 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.”
