Our History

35 years of innovation and success in additive manufacturing

On April 24, 1989, Dr. Hans J. Langer founded EOS GmbH in Gräfelfing, a small municipality south of Munich. This marked the first day in our history, which has been shaped by pioneering spirit, conviction and courage ever since.


Today, EOS is a global leader in the industrial 3D printing of metals and plastics and offers integrated solutions in additive manufacturing (AM). The company currently employs more than 1,350 employees in 15 countries and serves customers around the globe.
