A neat topic showed up in Hackaday this week about 3D printing magnets with specialized pole arrangements.  It references a youtube channel I watch with my nephew from time to time and you guys may appreciate it.

I recently watched the same printed magnets piece on YouTube.. It was a very insightful piece..

I love this technology.

People keep referring to it as 3d printing though. It's my understanding that the effect of the machine used is spot polorazation on a flat surface. I don't see any deposition of material or binding. The coolest part about this is the interactions between two surfaces created by precision spot polorazation.

 

Or am I thinking about this wrong? Is it "3d printing" magnetic fields?

If that's the case, maybe I need to expand my definition of "3d printing".?

Yeah it isn't 3D printed, in the original video, which was done by a really great channel called Smarter Every Day, he refers to the machines as looking like 3D printers, but that the just change the pole patterns in a blank magnet.
