I have to take issue with this. A friend of mine just had an RP part
made for a project he
is working on. It is essentially a kitchen cutting board, with an
opening for the thing he
is designing. (I'm being vague here to not divulge too much.) A
cutting board has to
be pretty tough to withstand normal use, and his definitely is. I'm not
sure which process
was used for this, but I believe it was the liquid polymer & laser
system. I thought that
this was an injection molded part when I first saw it, it was so solid.
