Did a very similar thing 20 years ago using DuPont and Acheson polymer thick film inks.

Mark,
Sounds like removal is not an issue.
How liquid tight would the 3D mask be?
Given that a 3D printer gives us a third dimension to the
mask, I wonder
what else can be done with it on the circuit board. What
would be very cool
is if the 3D printer could form the traces on a piece of
fiberglass. I
recall an old process that could put down fine wire and
cover it with glue.

Rick,
A heated bed is no real problem - I built one that works
pretty well.
But I'm not sure the wax won't stick to the copper
directly.
I hadn't thought about removing the plastic. PLA,
which is the plastic
I've been using, has only one solvent I know of,
Tetrahydrofuran, which you
can get on ebay. Heated Benzene is also supposed to work.
However, by
switching to ABS, you can use acetone to dissolve the
plastic easily.
