About ExOne Co

The ExOne Company (historical ticker: XONE) was a U.S.-based industrial company focused on binder jet 3D printing, with particular strength in sand and metal additive manufacturing systems. Before being acquired, ExOne was listed on the Nasdaq in the United States, making it a well-known pure-play name in industrial additive manufacturing for investors seeking exposure to advanced manufacturing and emerging hardware technologies. The company traces its roots to ProMetal, a division of Extrude Hone formed in the 1990s, and later became an independent company before going public in 2013. Over time, ExOne became closely associated with the commercialization of binder jetting, especially for foundry cores, molds, and other complex industrial applications where traditional manufacturing methods are less efficient.

Its core products were designed for customers in manufacturing, foundry operations, engineering, and R&D, with a particular emphasis on sand printing platforms and later metal applications. From a competitive perspective, ExOne held an early-mover position in binder jetting and was widely regarded as one of the category’s technological pioneers. However, it operated in a highly competitive market that includes multiple additive manufacturing vendors, all competing on throughput, repeatability, application breadth, and the ability to scale from prototyping toward production.

Geographically, ExOne had an international commercial footprint, serving industrial customers across North America, Europe, and Asia, reflecting the global nature of advanced manufacturing supply chains. Its strategic positioning was built around leadership in industrial sand binder jetting and a growing focus on metal solutions, with management frequently highlighting recurring revenue, backlog, and portfolio strength as indicators of commercial momentum.

As a result, ExOne ceased to exist as an independent publicly traded company, and its technologies and product platforms were integrated into the acquirer’s broader additive manufacturing portfolio. For investors, the key point is that XONE is a legacy Nasdaq-listed U.S. issuer whose public-company profile ended with the merger, so the most relevant “recent news” is the transaction itself and the subsequent integration of ExOne’s binder jet capabilities into Desktop Metal.
