With no hard feelings intended for Mr. Conner, he is a bit biased. I would also
suggest you call a Stratasys service bureau who uses their elastomer E20. The
flexible parts I have seen from that machine using that material are far stronger
than the DTM flexible parts I have seen. I'm not knocking DTM's machine, it is
great for many things, and I'm sure they will develop a great elastomer one of
these days, . . . but I suggest you look into both for yourself. Its the only
way to judge for your own application.
