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.

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.

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.

When is this coming to a machine sold by some company to consumers? I really want to make my PCBs at home.

A few days ago, I was thinking of trying a lower-cost, similar idea with a pen plotter.
