63 Dart bezels and 3D printing?

This makes me curious about other potential possibilities. How durable is the the printed product? Can it be painted plated etc? How does it hold up to heat ?
Once I master these dang bezels it's onto tail lights, dash components, trim clips, and everything else dang near extinct for this car! New materials are being made all the time so hopefully by the time I get the CAD and sizing/a perfected on all these there will be some new plastic (better than abs) available and easier to use.
