ExOne Corporate Headquarters

History of ExOne

Over 40 years of manufacturing technology experience, including additive processes.

The ExOne Company (ExOne) was founded in 2005 as a spin-off of Extrude Hone Corporation, a global supplier and developer of precision nontraditional machining processes and automated systems for more than 50 years. Three-dimensional printing emerged as the core technology for The ExOne Company, which currently supplies services, systems and solutions for manufacturing in the digital age, including three-dimensional printing in industrial grade materials such as sand and metals.

History of Sand Printing

Digital part materialization for the sand printing business began in 1999 when a group of engineers at a start-up company called Generis in Augsburg, Germany developed the prototype 3D printer for making sand casting molds and cores. The first printing system was sold to BMW AG in 2001. Generis was focused on the development of machines and processes for sand and investment casting before it was divided in 2003 into ProMetal RCT for sand and Voxeljet for investment casting. As a division first of Extrude Hone Corporation and then ExOne, ProMetal RCT developed a worldwide market for sand printing with dozens of machine installations. A smaller printer was developed in 2004 for printing with different materials and binders. With the introduction of the S-Max in 2010, ExOne released the largest 3D sand printer in the world, redesigned for production flexibility and efficiency. The development and production facility in Gersthofen, Germany now operates as ExOne GmbH. The ExOne® 3D sand printing business has grown from a handful of engineers to a worldwide team with operation and support facilities in Germany, the United States and Japan. ExOne is the global leader in sand printing systems.

History of Metal Printing

Extrude Hone (ExOne) became the exclusive licensee in 1996 of the 3DP (three-dimensional printing) process developed at Massachusetts Institute of Technology (MIT) for metal parts and tooling. Since that time, the company has been awarded over $14 million in research contracts by various organizations including the Office of Naval Research, the National Science Foundation and the National Institute of Standards and Technology for development and commercialization of the process, materials and equipment for defense and commercial industrial applications. In addition to process efficiency improvements, our machines are capable of printing in materials such as silica sand, ceramics, stainless steel, bronze and glass. ExOne is in varying stages of qualifying additional industrial materials for printing to meet the needs of our industrial customers. Equipment developments have resulted in the largest build volume available in the metal additive manufacturing industry, along with significant increases in production rates. Current applications range from heavy industrial equipment, such as impellers and tooling, to decorative and consumer applications.

Now, as much as ever, ExOne strives to be a partner for companies making the transition to integrate industrial 3D printing into traditional manufacturing operations.
