I use a 50/50 Mix of Resione M58 and TH72 for most prints. This is an expensive resin, but it provides a good amount of flex and durability without sacrificing detail.

I print at 30 microns which nearly eliminates all visible print lines depending on the print. This layer height nearly doubles the print time versus standard 50 microns but the difference is worth it.

I use specialized support profiles to keep support marks to a minimum. Less post-processing time means cheaper parts for you!
