Homebrew PCBs

Resolution to do 5mil trace/spacing would be very nice.  I'm not very
familiar with 3D print heads.  Can you recommend any pictures online of what
the work end looks like on a print head?

Jeff,

No straight answer here. What resolution would you want? 

From Solidoodle, one 3D printer company:

Precision:
. The resolution of the printed part is typically determined by the height
of each layer
. Typically we print at a layer height of .3mm, which gives a nice surface
finish and quick print time
. It's possible to print hi-resolution parts at a layer height of .1mm,
which produces top-notch looking prints
. Clarification: the precision of the printhead in the horizontal plane (X-Y
direction) is about .011mm (about 2300dpi). However, this number is a little
superflous because we are extruding ABS plastic through a relatively larger
.35mm nozzle, and all ABS plastic oozes a bit. So a more realistic &
practical estimate of resolution in the horizontal plane is about .1mm. And
to be crystal clear - this creates great prints. Trying to define the
resolution more accurately than this is similar to trying to define the
position of a garden hose nozzle to within millimeters - it's essentially
meaningless since the water is going to expand anyway.

What kind of resolution can a 3D printer achieve? Would the resolution be
enough for PCBs?
