i'm building a kitcar and i need some headlights and taillights printed in Polycarbonate. There is already a 3d model, just need somebody who knows a thing or 2 about 3d printing and has the equipment.
You won't be able to get the clarity that you need for the intended use. It would take many many hours of post print work and that's even if it does work. You would be looking at a high temperature FFF machine to do the work and even then I would question the safety of something like this in the event of a crash.
