Hello,

Would you mind precise your question ?

I'm a metal 3D printing specialist but i don't see what particular advantage you want from 3D printing for a Yagi-Uda antenna if it's a normal design. We can provide hi strength materials, tubes antenna (i recently print some wave guide tubes for satellites antennas), but simple tubes to assemble are too... simple for us ! Just to joke we can print nearly everything, and this is very big advantage for 3D printing.

First, which part do you need to print ? A plastic assembly part, a metal part, electrical conductor or not ? Magnetic permeability ? Prize ? Number ? Strength ? To choose the correct material, and there's too much choice to explain there.

In second you need to tell us how much parts and size of the parts to choose the correct technology for the printing...

Best regards,

Daniel FRAGNIER

thank you so much sir,
