First Order for Its Newest, Fastest and Largest Capacity 3D Machine Platform
for Printing Metal and Ceramics

NORTH HUNTINGDON, Pa., April 1, 2013 (GLOBE NEWSWIRE) -- The ExOne Company
(Nasdaq:XONE) ("ExOne" or "the Company"), a global provider of
three-dimensional ("3D") printing machines and printed products to industrial

The machine debuted at the International Manufacturing Technology Show in
Chicago in September 2012. The Company has received strong global interest in
the capabilities of the M-Flex industrial 3D printing machine since being
introduced.

David J. Burns, President and COO, noted, "Our new M-Flex brings a higher
level of productivity for a manufacturer of metal and ceramic parts using our
unique 3D printing process.The early acceptance of this dynamic new machine
is extremely encouraging for us and we expect customer interest to translate
quickly into orders."

The M-Flex provides a larger output capacity than previous models with speeds
that are ten times faster.As a result, total volumetric output per unit time
is significantly greater providing compelling economics for replacing
traditional machines for parts manufacturers and OEMs.A highly flexible,
user-friendly machine can print industrial grade metals and ceramics. It is
ideally suited for producing complex geometry with high accuracy.
