3D-printed antenna radiation patterns in color [video]

Is it that much more "enlightening" to 3D print vs just rotate the model on a computer screen? I can rotate a rendered model and get a pretty solid idea of the shape. I don't have to hold a physical model.

This makes me wonder: is it possible to submerge the antenna in a special fluid or powder and send some modulated current through it, so that said fluid hardens in form of a radiation pattern? We could then MR scan it and see the real pattern in 3D. It would be super interesting to compare the result to a simulation. Any ideas on what that fluid should be?

Do a helical or &quot;quadfilar&quot; haha throw some words in<p>Like that color, I bet you could print a pretty convincing peach

I am more impressed at that ability to blend colors on a print, but like you would on an ink-jet printer.

These 3D prints are amazingly perfect compared to what I&#x27;ve been able to achieve. With what methods&#x2F;hardware can I achieve something similar when it comes to shape&#x2F;texture?<p>What about the colours?

Nice, but antenna patterns are typically shown on a log scale. It would probably be better if he&#x27;d 3d printed on a linear scale, which would give a better physical idea of what the antenna is doing.
