Hi, All
Is there any way to increase the wall thickness of quick cast part? In this
way, the part could be stronger.
Thanks & Best regards.

Water/humidity would be a concern if you are still using first
generation
epoxy resins such as 5170 or 5180, but shouldn't bother second
generation
resins such as offered by DSM or RPC. Truth to tell though I have
used plain
wrap IPA on even 5170 quickcast parts for the longest. Now that I
use a
humidity resistant resin it would be even less of an issue, IMHO. No
point in
wasting money on "pure" solvents if its not necessary. Of course you
should
make an effort to keep the solvent from getting inside the part.
