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
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.

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

I'll go chase down what Micromark sells in their kit, which specifically states
it works with stainle
A while ago people were looking for some MTX-90's...

This just appeared for those interestednot my listing and all that..

That is really cool stuff!
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
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
