Dan,
I knew from Voltan's work that he was able to print a solder mask. (I was
never able to correctly cure the ink) and decided to try the Toner Dusting
process instead.
I was looking at replacing the black toner with other fusible fine powder,
hopefully a white or yellow one, to use as component legends. I had seen
some electrostatic painting on a TV show and thought it might work, though
most of the time the metal items were baked at a very high temp. I did a
search and found that the ES paint was also used on MDF, so a lower temp
fuse was possible. There are a few different types of ES powder.
I found some ES powder paint at SEARS for only $6 and am trying it. I am
told it also is available at some auto parts stores. The SEARS version has
slightly larger particle sizes.
I've just started playing with it. It seems to give a very thick coating.
Try to avoid the gold fleck version, The goldish particles are very small
and are hard to remove.
Toner dusting is a very simple process and easy to try. Like toner
transfer you have to fine tune it to your set up.
