Before I reply fully, what general location are you?
State, Suburb like.
Personally I'm out of Melbourne near Ballarat, but the hardware in
question is in the CBD in Melbourne.
I'll post here with specifics when I get access to it all again (next
few weeks or so).
I should probably also ask in this thread if other open tech is
suitable to post here (we have 4 or so 3d printers based on the reprap
printer firmware that we're looking to sell cheaply to homes where
they'll be used for more than printing Yoda figurines).

pretty much the same as for regular printers.... XY resolution and Z
resolution are typical. However, having said that, your results may vary...
the resolution of the stepper motors (or laser) may well exceed the
resolution of what can be accurately laid down, and certainly the minimum
thickness of a single line of material may be considerably larger than that
of the minimum resolution achievable kn a given surface.
that is all before you start talking about the actual achievable quality of
different configurations and technologies. laser stereolithography should
be higher resolution than filament for example.
I've only seen "production like" finishes achieved on top end industrial
machines. that requires resolutions around 30 microns and consequently
slow build times.TANSTAAFL

Yes from :
https://all3dp.com/3d-printer-resolution/
It seems consumer 3D printers don't do much better than 0.3mm;
but frankly even that seems better than the little 3Dprinted figurines
I have seen;
which off the top of my head seemed more like +/- 1.00mm !
Are the errors in 'dot size ' ( blob size ?) cumulative ?
From :
http://www.ilios3d.com/en/product-documentation/ilios-documentation-3dprint…
it seems there should be a "blobs per cubic centimeter " (bpcc ?) measure ;
analogous to dpi in a traditional printer ?

Well putting aside the contentious question of "There ain't no such
thing as a free lunch" :-) ;
we can probably agree there is a trade-off bteween build times and
resolution !

Correct, if you go from a 200 to 100 micron layer it is going to basically double your
print time.

These days you don’t list resolution unless you are dropping below 100 microns.
Describing the resolution is very hard since these is so many things that you need to take
into account, and not having just one this tuned right just takes it from a good print to
a bad print.
I think the easiest way is to show examples.
Gordon.
