I am not sure that's a good idea.
The way how filament printers work will lead to lots of
pores where humidity can accumulate. Not something you want.
Thermoforming sheets, on the other hand, gives a smooth, closed
surface. Additionaly, the tensile strength of the sheet after
thermoforming is higher than that of filament printed structures.
This means a radome can be thiner, which leads to less lensing,
which is the major source of phase center shift.
