Sponsored by Businesswire

ExOne Company
(Nasdaq: XONE) (“ExOne”), a global provider of
three-dimensional (“3D”) printing machines, 3D printed products,
materials and services to industrial customers, announced a new material
partnership program to make further advancements in metal binder jet
additive manufacturing.

The global enterprise program will focus on process developments and
powder optimization on ExOne’s metal systems, which will advance 3D
binder jetted metal and ceramic applications and deliver the most
innovative solutions to customers.

These partners will use their application engineering knowledge, powder
material expertise, and additive manufacturing process experience in
conjunction with ExOne’s additive manufacturing solutions, to produce
new materials and enhance process optimization with ExOne’s metal 3D
printing machines. ExOne is geared to launch the program with qualified
partners in the coming months.

John Hartner, ExOne’s Chief Executive Officer, commented on the new
program, “By partnering with elite material companies we further advance
our 3D binder jetting printing processes, which will propel us to the
next generation in materials and product development. We believe these
partnerships will retain our significant edge over other technologies in
the industrial additive manufacturing space and enable broader customer

As part of the material partnership program, ExOne will engage their
partners with global access to ExOne machines including the Innovent+™
and beta usage on the new X1 25PRO™, which will be revealed at the RAPID
event in Detroit, MI, May 20th – 23rd.
This high-resolution production machine is capable of printing metal,
ceramic, and other advanced material parts directly. The X1 25PRO™ will
utilize proven technology demonstrated on ExOne’s Innovent+™ and will be
shipping to customers later this year. The X1 25PRO™ can print standard
industry powders utilized in MIM (metal injection molding) and other PM
(powdered metal) processes.
