Iulian,
You have obviously got this project planned to a higher level than I
had anticipated. In theory, I can see no reason why a home brew piezo
DOD can't be achieved. Re glass pipette drawing, we tried this in the
early days of ink delivery using a CO2 laser to supply a burst of
thermal to the ink thru the glass which worked fine. The problem was
the end of the drawn pipette was always too ragged without a lot of
cost for consistency in drop formation.
I can't see why a single DOD assembly couldn't be used to lay a
resist layer direct to pcb. Would just take some time for a largish
board.
I also use turbocnc so a front end to that would be great.
Looking forward to your developments.
roger
