3PO build

That's an easy one to answer. Fiberglass is super strong stuff. If it weren't they wouldn't build auto body panels out of it. It's also not the easiest to work with and toxic stuff. And you have to make molds. It's just a much more involved process.

I feel like there's still a lot of research and experimentation to be done with 3D printing before we give up and revert to much more difficult processes.
