By SLA, does it mean resin printing then using some kind of metal coating process?

Or could you use something like SLS/SLM to print the whole model in metal?

Luneburg lenses for RF are 100% dielectric.

You print your lens with a known dielectric constant uv curable resin and it its good to go!

Methods like this are the ones that Lunewave (https://lunewave.com/) use for developing RF lenses for their ADAS system
