Been thinking a little more about that, one advantage I can see is a 
built in heater in the "bed" where the board sits, possibly will make 
temperature regulation easier for the preheat of the board.

Another advantage is that the print height could be adjusted easily, 
don't know if that is really needed, but would be simple to achieve.

The real cool way as I see it would be to totally replicate the print 
head itself from scratch, and make it a little more tolerant of more 
conventional resist type of inks, I know it is probably impossible, 
but that would be the ONLY difficult (or impossible) part to make.

The mechanical part of a printer is easily replicated using CNC 
control, its just that pesky print head.  

Just a thought.

As far as the head clogging, I will keep you posted, I modded a new 
printer so it will be interesting to see how long it lasts.  The 
preheated board definately prints and etches better.
