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. Attila Kinali -- It is upon moral qualities that a society is ultimately founded.
