I didn't understand you reliability question, if possible please explain a little bit more, what are your reliability criteria? Do you mean successful repeatability or reliable as TT :)? Please don't ask me to have 99% success rate.

I could be able print on pcb without any failure, it may be because of the printer that I am using. The main thing is, board needs to be clean, free of finger print, dust, and grease like required in TT process and you need to use as many colors as possible to decrease the effects of clogged nozzle. I am always using 3 colors. I didn't do 100 pcbs with this technique but I can say that, at least for me, success rate is much higher than TT. If someone plans to do double layer PCB with CNC drill or applying solder resist then there is no chance to do it with TT, either he needs to use photo-resist /dry-film or direct inkjet.
The curing process is the key for direct printing, you need to cure it until seeing some smoke on pcb, ink color becomes much darker and copper will be oxidized. I think after a few trials you will understand what I mean.
Good luck,

....successfully and reliably repeated. We have only heard from Voltan that it is do-able, but nothing about the
reliability. From Stefan's posts, his trials show a repeatability problem.
