I don’t know much about epoxy prints, but I’ve done epoxy casts from 3D-printed investment mold positives in the past. That’d probably be a massive PITA for a hand with so many small parts, but then again, so many small parts lend themselves to just printing the negatives in the first place, then casting the parts directly. Of course, I’d recommend reinforcing the epoxy with some sort of fibrous material— para-aramid/kevlar pulp/wastes are pretty cheap (meta-aramid/nomex if you’re concerned about flammability), linen even more so (I’d caution you away from fiberglass if you have any
hand-holding planned, though).
You’d also have to check water-tightness beforehand, and have some plan for patching tiny flaws (I just used a solvent to dissolve waste scraps of whatever material it was printed from, then painted on my makeshift “glue” to fix it up).
Not strictly necessary for non-structural parts, but if you do cast (and it’s in the budget), I’d recommend using a vacuum pump to pull out any voids during the process— it’s good practice, if nothing else, especially if you use the process for larger/load-bearing parts in the future (why yes, I did have a part fail spectacularly because of casting voids, how did you know?)
