On our SLA-5000: I can build a .007 hole diameter, but I have to change
build parameters which will effect accuracy. The length is dependant on
we are talking straight or curved. We are using RPC 100ND resin.
We have had very good results with the RPC resin. As you already know,
the hole is parallel to the platform it is more difficult. The cleaning
we use is similar to previous postings.
