Ahh, found some nitric acid.
The 6 molar solution should do nicely.

I do not believe anybody has suggested 50/50 copper sulphate/table salt yet.
For my first try, I was going to try a concentrated solution of ferric
chloride and voltage with stainless as the anode and cathode.
I do not know how it will come out.
I'll also go grab some copper sulphate to give tha
I've picked up on this discussion late, so don't know if anyone's suggested
this to try: 50/50 copper sulphate/table salt. Don't know if this will work
on stainless steel, but has been recommended for etching ordinary steel or
aluminium.

Really?
Well, that's worth trying.
Maybe a better etch could be gotten with the use of a combination of
ferric chloride and electrolysis.
That would probably mean a printer based press-n-peel system and a battery.
I am also interested in this method to make stainless solder stencils at home.

I had, of course, forgotten it. Here it is.

Thats it! I was looking for tiny beads several times, but havent found sich
a small ones. The height is important, 1.8mm is exactly what is inside
z566m!
I got a quote from a german company for ceramic washers, over 2 eur per
piece :-)

As far as the spacers, those could be molded in Ceramic Clay and fired
in a Kiln. The mold could be made in Silicon or similar, again the
prototype could be made on a 3D printer, or just turned on a lathe.

OK, I see what you mean. My interpretation of outgassing was wrong, I thought it had to do with gas leaving the envelope but you're referring to trapped gas leaving the metal/plastic parts. I don't know if that problem could be solved, maybe there is a different way that plastic parts can be outgas

Maybe one day it is possible/affordable to use a 3D printer to print
these cathodes and grids using a conductive plastic of some sort.
I would expect that the plastic would outgas rather easily, and would
not survive

I'll go chase down what Micromark sells in their kit, which specifically states
it works with stainle
Well, I mean the envelope is still glass but only the inner works are 3D printed. I had a quick search on google after my post and there is actually quite a development going on in electrically conductive 3D printing technology. Some claim "low cost" but not sure if that would be good enough to mak
Hi Michel,
[...] using a conductive plastic of some sort.
I don't know for sure, but you might face a hell of outgassing if you
use plastic.

I don't know about 3d printing the cathodes.
As for chemically etching these plates, I am pretty sure you won't have to
put the pattern on both sides of the plate.
You could completely cover one side of the plate with a even coat of etch
resist.
Then, you'll be able to put your design on the oth
