Uh. No it isn’t. SNR between 5 or so masts gives you the exact location of any cell device. This is how $oldemployer used to track them
Obviously not DED or binder jetting, and anyone who knows metal printing would see that instantly. DED has the resolution of a hot glue gun, laying down thick beads of molten metal that could never produce such a fine, intricate lattice - it's built for large-scale, rapid deposition, not delicate internal structures. Binder jetting is even more of a non-starter; you're essentially gluing powder together and then sticking it in an oven to sinter. That process leaves behind a distinctly porous, slightly grainy microstructure because the particles are fused, not fully melted, which looks nothing like the smooth, continuous, and fully dense solidified strands you see in this micrograph. This image screams high-precision, localized melting, which is the exclusive domain of powder bed fusion techniques like SLM or DMLS.

Everyone else managed to read it fine.
I say this in interviews just to look smart. And people think it’s revolutionary. Everyone loves an outspoken opposition -what do they know, where did they get this knowledge?!
Only a couple have ever pushed back and those that do are the companies that I want to work with.
A wild example, let’s delete a test that ensures a heart pump works at the correct duty cycle given its parameters. Now someone comes along and redefines milliseconds to microseconds for some unrelated component. The tests are all fine. Patient now has a 60000 bpm heart rate.
Stupid idea.
