Re: [Homebrew_PCBs] Re: Piezo Print Heads and Oil Based Inks

A product that looks like what i have in mind,
the table is moved, making the modification of the printer a very easy 
task.
I do not think we can get any more information on the printer, global 
sources supplyers
are not cooperative if you don't buy a huge number (though they send me a 
magazine
every few weeks - dunno why...)
the thing to note is that it can use solvent and water based:

I think water based is not much good because it won't dry on metal.
on the other hand acrylic paint would dry and would be water based,
and acts as a resist.


My best bet is still with the solvent type ink, like used by permanent
markers.
Someone here wrote "a collegue put a inkjet head on a flatbed and printed
permanent marker ink (1:1 diluted with alcohol) and it worked".
he wrote the marker was the same as they used to touchup boards.
You can for sure find it in the archives.

It is also quite well possible that the acrylic paint would work with 
piezo,
it did NOT work with bubblejet, which is obvious as the heat "boiling" the 
water
will make it clog terribly (which it did).

I guess i MUST try it, it would be a bit easier than TT and the quality 
would be better.
Also i could possibly prevent buying a new laser (for resolution). Inkjet 
printers
are MUCH cheaper.
