I stumbled upon this video recently... I thought you fine gentlemen would find it interesting. There must be an application for this technology in a planar design.

it is kind of multipole. like in flexible magnets. only thing is that multipole is not usable for speakers. it does have more force up close like for lifting or sticking it on the fridge.
the hand knob they used to let us see the snapping action is actually used for years in the parfum from Chanel blue
in the lid.haha
although it is more complex what they can do...... the detailed stuff they can do could be interesting
Thanks for sharing!

It looks like magnetizing field is applied in one direction or the other through the axis of pressing in very localized areas. In any other sense there is nothing printable about it. This would offer nothing to planar speakers that conventionally magnetized shapes can not already achieve better.
well yes and no. if you lok for plannars for instance you could make a perf plate out of magnetic material and magetise according to the layout of the membrane traces. just an idea
The new "technology" there would simply be the die to press a perforated cracker out of a thin sheet of NdFeBr material. After that you'd probably want to magnetize it with a rather conventional large set of poles. You could bother with "printing" large poles in tiny increments, but the result would be the same. You still run into the problem of low remanence across the pressing direction. In other words, you're probably better off with off the shelf blocks of stuff if you're trying to make a speaker. I'm still waiting for a solid neo pot magnet though. That would be kinda neat. Maybe you'd want a long shallow horseshoe, if you're strongly of the planar persuasion.
