The ExOne Company Awarded Order for New M-Flex Platform

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 customers announced today that it has been awarded an order for its newest machine platform, the M-Flex that is expected to ship to L'Université du Québec in the third quarter this year.

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.
