Just a question what the smallest layer has anyone done, successfully achieved, im researching first before I build my machine, and trying too understand a few concepts.

What attributes involved in layer thickness, as I pressume the finer the layer the better the print finish

Cheers

... with FDM/FFF-printing or other methodes too?

With different fabbing methodes (UV-printing, etching, lasercutting, LOM, ...) I've achieved thicknesses, sizes and accuracies in some ten microns with DIY-machines ... with access to comercial systems even sub-microns

Fdm/fff

... nozzles can have 0.2mm bore diameter, but 0.3 to 0.5mm diameter is common - with this nozzles you can print layer heights down to 0.1mm, some people managed to print even with 0.05mm height (remember a post where 0.02mm were mentioned).

The possible printing accuracy depends mostly on your experience and skills, then on the stiffness of the machine, filament quality ... and some other external parameters too ...

using slic3r I've tested layers as low as 50 micron on ultimaker using makergear 0.35 nozzle
