I wonder if surface prep with some ultra fine grid sandpaper or emery cloth would allow the wax to adhere better

the printer is nowhere near accurate enough to reprint exactly the
same twice, as you can see in the third image the wax did not line up
with the previous printing of the same thing:

it turns out the problem was not that the wax wasn't sturdy, but that
it did not adhere to the copper until it went through the oven for a
minute.

Nice! You could also try running the Pyralux through the printer multiple
times to build up a sturdier wax layer. Assuming you can line up the paper
accurately enough, of course.

Last tuesday at sudoroom I used the Phaser 8560 printer to print circuit
patterns onto pyralux material (kapton coated with copper) and then etched
them in ferric chloride.

the result was that I was able to make circuits very quickly and easily,
even though it was the first time i did it this way.

if other people want to etch circuits at sudoroom, I can help.  email me
if you want to coordinate.

The circuit i made was single-sided but you can do multiple layer
circuitboards pretty easily, obviously, by putting these back-to-back.

if you wanted to be even more advanced, you could use the laser cutter to
burn holes in the pyralux (assuming that works) and solder through those
holes from layer to layer.

also did i mention this material is flexible like paper?  we can make
wearables, cylindrical circuits, watches...
