After a year of trial and (lots of) error I'm finally having to admit that figma-style joint-systems are just not something that can be done with SLS on Shapeways for 1/12 scale small things like animals. Scultped joints really do hold up more consistently in the end with sockets, swivels, and hinges.
My goal was to leave the joints separate to have people only needing to replace joints instead of entire limbs or body parts for custom figures, but for human and human-sized animal figures at 1/12th scale this just isn't really feasible.
