I do not claim any extensive knowledge, but given the projected growth 4 3D printing + the other uses if this division isn't a $30m+ rev producer in 2 yrs I will be surprised. Given that Pyro just leased the new production facility 3 moths ago and is beginning production already ramping production should not be a problem. 
I view this buying opportunity as stock passing from weak hands to strng! I am a part owner not just a share holder and plan on being one for some time. Added more today!
