The Sanders MM6B was slooooooow but ACCURATE and RESOLUTE and SMOOTH on ALL
surfaces.

The newer Solidscape machines are a lot FASTER and more ACCURATE, RESOLUTE
and SMOOTH on ALL surfaces. So, even if they are sloow, they are worthy of a
serious look.

I like to precision cast the patterns which they create. They produce the
most intricate parts of all of the RP processes.
