I've done detail casting in resin:

You need to use a low viscosity resin. Smooth-On's Smoothcast 300 is quite popular. I've seen it online and in art stores. The Alumlite stuff in hobbyshops is nearly worthless for detail parts...unless you like rejects.
I use a sewing needle in a pin vise to work the air bubbles out of the mold after pouring the resin in. talc (baby powder) in the mold is also helpful.
3D printing might be an easier path...
