My earlier posting on this subject is somewhat messy as Bill's original letter and my reply got mixed up. I am reposting it for clearness. Now, my reply is italicized.

We have been beta testing SOMOS-6110. As of today, we built about 150 customer parts. In general, parts are comparable to 5170 parts. In fact, once parts are finished, it is difficult to tell if they are made of 5170 or 6110. Bubbles appeared to be fewer or the same and vertical walls appeared smoother. Horizontal surfaces showed a little more distortion (when checked with a straight edge) than their 5170 counterparts. Speed wise, 6110 is nearly twice as fast as 5170. This significant difference in build speed was a big incentive for us to try 6110 in the first place.
