>>What is the nature of the contract between SGLB and EOS? <<
honestly speaking: I have no idea...
You were talking that EOS is the big fish...agreed in the moment yes and I believe that Trumpf will be the real big fish even bigger than GE Additive or better Concept Laser within the next 5 years...
Trumpf is the world leader in laser applications...
On the other hand Trumpf can not help Sigma Labs in the short term with revenue...
