David:
My approach is
Resolution: Measure the radius at the intersection of two and/or three planes.
Accuracy: Measure enough parts to establish the process capability to print
tolerances, in the x, y, and z directions.
Surface finish: Compare your RP parts at 45 degrees to and parallel to the
build plane with the usual machioning standards, or use instrumentation.
