Thanks for the reply. It was most interesting to hear your view about the
process. It helps give one a balanced perspective of the processes

I have seen some very good parts/tools made using the DTM RapidTool process
at the Technical University of Munich. DTM also have an impressive
collection of parts/tools (as one would expect) and EOS can produce
impressive parts/tools using their EOSINT M machines. As you point out, I
think there is still room for improvement in the capabilities of both
companies machines (all patent issues aside). How much can they be improved
?? ...... I guess only time will tell.
