It was interesting to know that there are several direct metal systems
available which can make functionally graded material part. I was expecting
to hear from the people in RP companies. I heard from one or two
personally. Direct Metal Systems like POM, Solidica and LENS can make multi
material parts. It would have been interesting to hear briefly about the
research work too in the list.
