Me.....I have had Somos 6110 for a little over a year.

Seems about the same in accuracy as any other resin.... Accuracy really
your machine calibration, operator experience, and environment. I got
6110 because I have about 40-70% humidity in the lab here and being a
university I have little hope of getting an environmentally stable
situation. 6110 seems to like the higher humidity. Post process is not
any problem other than using TMP when I really like to use alcohol. I use
both but TPM works better. I have had a few sticky parts when I insist on
using only the alcohol.
I mainly do ASIC build styles and the parts are really nice.....my
customers seem to like
the finished parts. I have built a few Quickcast parts and they seem to be
fine and drain well. I do not have any Q-cast parts sitting around so I
can not comment on the aging process of the final parts.
I make sure that with any multiple model builds that I use parameters for
trapped volumes since my machine seems to dislike any such animals and will
destroy any thing that looks like such. I have not used 5170 so I can not
compare build times nor
any other charateristics. I have been a Dupont user since they first
