UPDATE: Apparently I'm way behind on my 3D skilz. There are two spongy 3D printing materials nowadays; Ninja-flex, and Poro-LAY. They say Ninja-flex is like printing with rubber, and Poro-LAY is like printing sponge. I don't think either is exactly like the polyurethane Nerf uses, but at least we're moving in the right direction. But I still haven't found any STL files for a safe, one-piece Nerf dart design.

I still contend that it's probably not worth the cost of the resin, your time, and the wear and tear on your printer to make Nerf darts. For instance, these NFStrike flatheads are really good darts, and they're only 3¢ apiece. They're safe, nicely made, the heads don't come off, and they're remarkably consistent. And even if your kids wreck a few, you'll have a couple hundred spares 😉
