About ExOne

ExOne is a global provider of 3D printing machines and 3D printed and
other products, materials and services to industrial customers. ExOne’s
business primarily consists of manufacturing and selling 3D printing
machines and printing products to specification for its customers using
its installed base of 3D printing machines. ExOne’s machines serve
direct and indirect applications. Direct printing produces a component;
indirect printing makes a tool to produce a component. ExOne offers
pre-production collaboration and print products for customers through
its network of ExOne Adoption Centers (“EACs”). ExOne also supplies the
associated materials, including consumables and replacement parts, and
other services, including training and technical support that is
necessary for purchasers of its 3D printing machines to print products.
The Company believes that its ability to print in a variety of
industrial materials, as well as its industry-leading volumetric output
(as measured by build box size and printing speed) uniquely position
ExOne to serve the needs of industrial customers.
