2- Extruder mechanism that is geared to have stronger torque to push Flexible filament

1- I have no idea. For the most part all the common printers have a Z system that is good enough to print any reasonable resolution - the problem is that with very thin z layers it can take days or weeks to make a print. So the problem is time, not Z accuracy. Usually.

2 = stronger doesn't help - the flexible filament if you push it hard at all will turn into a sine wave going back and forth in the bowden or maybe slipping out of the feeder without going to the nozzle at all.
