Yes - if you use STL format the resolution will be fixed at the time you export. Like Burr shows above the "Divide larger than" setting in MoI can be useful for forcing polygons to be more finely diced throughout the shape.

Once they are reasonably small enough, it becomes difficult to notice them in the final result.

But if the process permits like with CNC, you should transfer your NURBS data into the CAM program so that it will be able to have the highest fidelity model definition available for it to calculate toolpaths off of. Most CAM programs will accept NURBS data in IGES or STEP formats.

3D printing though is based off of STL. Usually though the resolution of the print process itself is more noticeable in the final result than the polygonization.
