I'm very surprised these haven't taken off by now. They seem extremely useful and these guys have been pushing them for several months now if not longer.

The one thing that prevents them from entering customer market in every day use is that magnets can affect many things. Simple example - I had cover for my phone with a magnet closure. It wasnt affecting my phone in any way, but few times I put parking card next to it and it wiped out all the information from it forcing me to chasing parking office to get it re-printed.

  But wouldn't this be the solution to your problem? If the pole reversals are tightly packed, it looks like the field lines could be designed to not affect other objects, even in close proximity.

    As long as facing right direction. Its just one example and actually quite good - I would keep initially the ticket inside of the case, so it would come close to magnet anyways.

  When I was at uni we spent some time in the lab playing around with Magneto-optical film and polarized light, it was supposed to demo the Kerr Effect. I had fun with an old floppy disk - you could bring a bar magnet close to the disk's film and watch the magnetic domains flip under the microscope. Would be pretty cool to print some patterns using this technology and view it the same way.

    > Kerr Effect Applied Science (which has many great videos) recently did that demonstration using an old magneto-optical removable disk. He was able to get a very nice example of the effect that is visible with the naked eye. https://www.youtube.com/watch?v=UTquUbvzJII https://www.youtube.com/watch?v=UTquUbvzJII If you like that video, the previous video on the Faraday effect is really cool; I had no idea a solenoid rotates light polarization. https://www.youtube.com/watch?v=XhU-nNiAgtI https://www.youtube.com/watch?v=XhU-nNiAgtI

  Supposedly this reduces the distance to affect sensitive electronics/cards.

It’s been a few years. I agree the technology is very clever and should be widely applicable. I think not enough industrial designers / mechanical engineers have played with them yet to really explore possible uses, other than a few simple things like cabinet latches and magnets for hanging art on walls with iron-filing paint. From what I understand, a bunch of their funding came from the Navy, who wanted to use them for transferring torque on ships without a solid (breakable) shaft. Anyone in SF can sign up for a TechShop membership and go play with the CMR magnet printer they have there.

Remember that engineering might not move as fast software development.

  The tech isn't novel, it's the application that is. You could mass produce this today.

Printing seems too slow for the mass market.

  If you know your design you could have a jig with many "print heads" and print all the maxels simultaneously.
