Orders are now being accepted; systems to be delivered starting late 2019

NORTH HUNTINGDON, Pa., November 13, 2018 – The ExOne Company (Nasdaq: XONE) (“ExOne”), a global provider of three-dimensional (“3D”) printing machines and 3D printed and other products, materials and services to industrial customers, today announced the release of its newest system, the X1 25PRO™. Combining the fine metal injection molding (“MIM”) powder capability of ExOne’s INNOVENT+™ machine with production volume capability, the new X1 25PRO™ is positioned to address the needs of MIM, powder metallurgy, and manufacturing customers seeking a larger platform solution for producing reliable parts in a production environment.

The new X1 25PRO™ offers customers the ability to produce fine quality parts from a variety of materials including: 316L, 304 L, and 17-4PH stainless steels; Inconel 718® and 625; M2 and H11 tool steels; cobalt chrome; copper; tungsten carbide cobalt; and many others.

Rick Lucas, ExOne’s Chief Technology Officer, noted, “We are pleased to bring the new X1 25PRO™ to market to satisfy the needs of industry for high quality, functional, production-volume parts. ExOne has a pioneering legacy of being on the cutting edge of introducing materials and processes using binder jetting. We currently have machines installed in customer facilities in more than twenty countries around the globe and we are proud to bring innovations like the X1 25PRO™ to realization. Our X1 25PRO™ is the first of two machines that we are introducing by the end of the first half of 2019, utilizing our state-of-the-art patent pending MIM powder processing machine technologies. We believe these new production machines will be the most flexible and highest performing binder jetting machines in the market.”

The X1 25PRO™ allows customers of ExOne’s INNOVENT+™ platform to scale up to a mid-size production platform using the same powder metallurgy standard powders they are currently using. The platform will focus on the MIM, powder metallurgy, and mechanical engineering market applications.

ExOne will begin taking orders for the X1 25PRO™ system immediately. Stop by ExOne’s booth at the Formnext additive manufacturing trade fair in Frankfurt, Germany from 13 November to 16 November to learn more about the system details. Customers will have the opportunity to see the 25 PRO on display at the RAPID + TCT 3D event in Detroit on May 21-23, 2019.
