The HP print head chip itself is all silicon, and should survive acetone.

The surrounding plastic and flex cable – I wouldn’t bet on it.

However!

As acetone is my favorite solvent, and as I have a spare dead cartridge, I’ll stick one in a jar of acetone and see what happens.

Best case scenario: full survivalist.

Good case: flex cable and print head survive, and that will allow us to bond the print head to a milled metal cartridge to hold the acetone.

Worst case: a single bare silicon chip floating in goo.

And speaking of goo – instead of printing with pure acetone, how about printing with an acetone/plastic mix?

That, combined with incrental baking, should cause less wicking of the acetone through the powder bed, and a stronger part.
