You are me both Nobahamas,
its exactly my understanding of the market at present when it comes to metalprinting.
MTLS, AMAVF, VJET, XONE, SLM Solutions are the companies to watch in 2016. Unfortunately EOS is a private company, otherwise I would ad it to the list as well.
In the bioprint arena the only company I know is ONVO but I would be more than happy to be informed of other companies in this field.
Cheers and good investing,
