For me, the function of a bodyshell is it's form. If it doesn't look fabulous and reasonably accurate, then I don't see the point.

But to be fair, that's nothing to do with 3D printing or any other form of producing a bodyshell, it's just my general preference.

It's absolutely amazing what some people can do to a 3D printed bodyshell, that takes time, effort and skill...the first two I have, the skill I don't have so do the best I can and I'm happy with that.  Others have used the exact same bodyshell as myself and turned it into a show stopper, that's what some people focus on, the lap time ability of that car being irrelevant.
