I have been on the list since the early 90's (bought an LOM system in
1991). I still have to explain - in great detail usually - to
customers that want RP parts or RTV/urethane parts what is possible -
etc. I really thought by now that the understanding of the technology
and applications would be more wide spread. I think part of the
problem is due to the continued erosion of manufacturing in the US.
