If you need detail in more than one axis, you should use a smaller nozzle and lower speed. Along z-axis, the feature size limit is layer height, and along XY it's linewidth. Layer height can be very small with any nozzle (I've seen as small as 50 microns), but linewidth will typically need a smaller nozzle hole to work well, particularly to get below 100 microns.
