A friend uses an HP print/copy/fax machine in her dental practice.  After
some eight years it stopped working due to a jammed carriage--the dried ink
had built up in a stalagmite from the sponge well and blocked movement of
the print head.  It had the consistency of soft plastic.  Guess that printe=
r
doesn't track ink buildup.  Since I cleaned it out (a messy job involving
sharp instruments and methanol) it's been working fine.  That was two years
ago.

I believe one could do 3D fabrication using that ink, but it would be
fantastically expensive.
