Abstract

Direct digital manufacturing, or ‘3D printing’ as it is more commonly known, offers a wealth of opportunities for product and process innovation, and is often touted to ‘revolutionize’ today’s manufacturing operations and its associated supply chains structures. Despite a growing number of successful 3D printing applications, however, evidence of any displacement of traditional manufacturing is limited. In this paper we seek to separate hype surrounding DDM from economic reality in order to ground the future research agenda for the Operations Management field. By opposing direct digital manufacturing with traditional tool-based manufacturing, we show that direct digital manufacturing so far lags behind by several orders of magnitude compared to traditional manufacturing methods. Yet we also find that direct digital manufacturing clearly is on an improvement trajectory that eventually will see it being able to compete with traditional manufacturing on a unit cost basis. As such we conclude that direct digital manufacturing will increasingly challenge operations management researchers to question established practices such as scheduling, batch sizing and inventory management in low-volume, high-variety contexts. Furthermore, an increasing adoption of direct digital manufacturing will drive structural shifts in the supply chain that are not yet well understood. We summarize these challenges by defining the research agenda at factory, supply chain, and operations strategy level.
