This is a much more promising technique from Applied Science: https://www.youtube.com/watch?v=UIqhpxul_og
> The Meta-NFS device concentrates microwave energy into a zone smaller than 200 micrometers, about the width of a human hair, enabling electronics to be printed onto bone, tissue, and living plants
> The Meta-NFS works by heating from within the deposited material itself. A conventional transmission-line microwave applicator
I can't think of any sci-fi plot that anticipated this. Heating a material from within to apply on to sensitive mediums like skin tissue potentially opening applications that go beyond nano-suit imaginations.
A few days ago, I was thinking of trying a lower-cost, similar idea with a pen plotter.
When is this coming to a machine sold by some company to consumers? I really want to make my PCBs at home.
Yes! Hopefully we can soon 3D print our own RAM - that way those greedy AI companies and their evil RAM hardware manufacturers's plan to rack up the price, will lose one blackmail tool.
Yeah but it still can't make my food hot in the middle
The article reads like they are talking about the traces. What about components like surface mount resistors, IC's, etc?
The examples I noticed were things like antennas, grids, a microspring. I didn't see anything resembling a full circuit.
