[amsat-bb] 3D printing (was 70 cm Lindenblad progress)

[Steve Kristoff]

I am pretty ignorant with respect to 3D printing, but this question just popped into my head. Is there any kind of electrically conductive material that can be used for 3D printing so you could print the actual antenna?

I built a patch feed for 1296 MHz and a folding fabric dish using many 3D
printed parts.  I have some experience testing parts under stress in hot
weather.

PLA is great for prototyping but will fail quickly outdoors and then be
eaten by squirels and deer.  :0

Nylon is strong but softens significantly in heat.

ABS or PETG are UV stabile and relatively heat resistant.   PETG is great
because it prints straight and strong.

3D printing will be a game changer for ham antenna builders.
