Sure, "in the future", but right now, most common 3D printers seem to only operate with a precision of ~0.5 mm.
I've thought about trying to make a crude 3D printed copy now, with a current generation printer, and polishing the ABS with acetone, to produce a higher quality copy manually.
The resistance of the springs on my building's outer door lock give a pretty smooth, low-resistance action that plastic (or maybe even wood, but not hard wax or soap) might tolerate, but then I'm paying $3,000 for a copy...
