Anybody out there looked into 3d printing waveguide and then painting it with shielding paint.
What frequency are you shooting for ?
What is the shielding paint made of ?
Many 3D print materials will not last very long in sunlight.
I would like to be able to use it on 10 to 24 ghz and I don't know whats in the paint I found. I Do know the paint is from lowes hardware. And sunlight won't be a problem as it will be in a enclosed box
Shielding paint should be very lossy to do it's job well. There are Nickle based conductive paints that would likely work better.
If you print in PLA you can then cast the part in Aluminum using "lost PLA"
I didn't think about casting it. I'll try printing first and conductive paint and see how it goes. I can always cast it later.
