ExOne Announces Kennametal as Inaugural Beta Customer for New X1 25PRO™ Production Machine

The ExOne Company (Nasdaq: XONE) ("ExOne”), a global provider of three-dimensional ("3D”) printing machines, 3D printed products, materials and services to industrial customers, today announced its initial X1 25PRO™ beta machine partnership with Kennametal Inc. (NYSE: KMT), a global leader in material science, tooling and wear-resistant solutions.

During the beta period ExOne and Kennametal will have an opportunity to evaluate the new X1 25PRO™ machine and trial test new materials and processes. As a multiple machine customer, Kennametal is on the cutting edge of binder jetting technology adoption for additive manufacturing.

"We see binder jetting technology as a key enabler for our differentiated, high-performance wear materials, such as tungsten carbide and Kennametal Stellite™ alloys,” said Sherri McCleary, Director, Business Development Additive, Kennametal. "Kennametal is uniquely qualified to supply these additive materials and components, and we’re pleased to collaborate with ExOne on cutting-edge technology with the potential to help us advance from prototyping to serial production.”

"Working with innovative, global companies like Kennametal is another important step towards integrating industrial 3D printing into existing and new production lines. We are excited to bring Kennametal on as a beta user and look forward to beginning the testing program”, said John Hartner, Chief Executive Officer, ExOne.

The new X1 25PRO™ will be revealed at the RAPID + TCT event in Detroit, MI, May 20^th – 23^rd. This high-resolution production machine is capable of printing metal, ceramic, and other advanced material parts directly. The X1 25PRO™ can print standard industry powders utilized in MIM (metal injection molding) and other PM (powdered metal) processes. ExOne has already received a production order for the X1 25PRO™. The X1 25PRO™ will utilize proven technology demonstrated on ExOne’s Innovent+™ and will be shipping to customers later this year.
