ExOne is a global service provider and manufacturer of 3D printers, 3D printed products and materials for industrial customers. The company’s headquarters are in North Huntingdon, PA (USA), while it has a German site in Gersthofen (Bavaria).[1]
The company specializes in the development and production of printing systems based on binder jetting technology. ExOne has five sites around the world and is among the leading suppliers of industrial 3D printing systems. The company employs around 300 employees around the globe and generated an annual consolidated turnover of approximately USD 53.3 million in 2019.[2] In the financial year 2018, the annual consolidated turnover was around USD 64.4 million.[3]
History[edit]
ExOne’s story began in 1995 with the foundation of the ProMetal department within Extrude Hone Corporation. From this department, which developed 3D metal printers, the ExOne Company was created.
In 1996, Extrude Hone received an exclusive license for a 3D printing procedure which was developed at the Massachusetts Institute of Technology (MIT), and is known today as binder jetting. Two years later, in 1998, Extrude Hone introduced the first commercial 3D metal printer based on binder jetting technology, called the ProMetal RTS-300, with the first system being installed at Motorola. The second 3D metal binder jet printer, the R10, was launched in 1999.[4]
In 2002, Extrude Hone entered the sandcasting market with its S15 model, which was able to print sand molds and cores. In 2003, Extrude Hone concluded a licensing agreement with the German company Generis GmbH. Rainer Hoechsmann, who co-founded Generis, was later named Managing Director at ExOne GmbH in Gersthofen, where the company is still active today.
Extrude Hone was sold to Kennametal in 2005, with the financial assets of the 3D printing business being transferred to The ExOne Company, LLC. The name is derived from “Extrude Hone,” the name of the company founded by Larry Rhoades decades previously on the basis of a patent registered by his father.[5]
2007 was a year of abrupt change for the company. Founder Larry Rhoades died unexpectedly and ExOne was purchased by Rockwell Forest Products, a company wholly owned by S. Kent Rockwell.[6] Rockwell has since managed ExOne as the Chairman of the Board of Directors. He was also the CEO between 2013 and 2016, as well as the interim CEO between June 2018 and May 2019.
In 2013, the company was restructured and underwent a name change, becoming The ExOne Company and successfully going public on the Nasdaq.[7]
John F. Hartner has been Chairman of the Board of Directors at The ExOne Company since 2019.[8]
Sites[edit]

Technology[edit]
The patented ExOne binder jetting procedure is based on the powder bed and inkjet head 3D printing procedure developed at the Massachusetts Institute of Technology (MIT) in 1996, and is known as a generative production process. This uses 3D CAD models as the basis for manufacturing components.
The binder jetting procedure uses a printhead which sprays a liquid binding agent onto a powder layer in a targeted manner, in order to connect the particles. The base of the building platform is then lowered and a new powder layer applied. The process of layering the powder and binding agent results in the component being created, layer for layer, over time.[9]
Compared to other additive manufacturing processes, binder jetting is unique as it does not use any heat during the process. Other additive technologies use a heat source which can create internal tensions in the components; these then have to be dissipated in a secondary post-processing step. In addition, the components are supported by the loose powder during binder jetting, meaning an additional support structure is not required for this procedure. One advantage compared to the traditional manufacturing methods is the ability to print large components with very complex geometries in a short period of time.[10]
Applications and sectors[edit]
From industrial 3D printing of prototypes, through the production of limited run series, all the way up to the integration of 3D printers in production lines for 24/7 series production, ExOne printers meet the requirements for different applications across a wide variety of sectors. Examples of sector-specific applications include:[11][12]
Automobile industry[edit]
Automobile manufacturers can use 3D printing systems to create prototypes, as well as in the development of components and gearbox cases, for example.[13]
Casting industry[edit]
Casting tasks, prototype models, quick production development as well as series production are departments in which 3D printing often enables foundries to reduce work and material costs, as well as improve design control.[14]
Oil and gas industry[edit]
3D printing assists in manufacturing parts such as agitators, pumps and valves with improved wear properties, increased corrosion resistance, strength and density for use in oil and gas drilling applications.
Decorative art[edit]
3D printing enables to users to realize unique and creative ideas, e.g. decorative objects, jewelry or film props.
