Researchers develop 3D printed filter for ‘forever chemicals’ in water
Using 3D printing, researchers developed lattices which removed up to 75 per cent of PFOA, one of the most common forever chemicals.

"naturally we won't release the stl files or any models of any type. we wouldn't want normal people making these"
Pretty sure normal folks don't have indium oxide at home, nor a 3D printer that can handle the material correctly.
'Scuse me neighbor, can I borrow a spool of indium oxide filament?
"In three hours, the monoliths removed 53 per cent of perfluorooctanoic acid (PFOA), one of the most common forever chemicals also called PFAS.
Moreover, by heating the monoliths at 500°C and reusing them three times, researchers observed that at least 75 per cent of PFOA was removed."
So yeah, like 9+ hour process. Gotta cool them down between each run. I looked on wikipedia, Indium is about $167/ Kg. What if, I know this is crazy, what if we stopped poisoning the planet, and ourselves?
Unless you have indium oxide filament, it wont do any good. This is more of a scientific proof of concept, rather than an engineered drop-in solution.
It is possible they don't trust this to be food grade yet, or maybe it traps a lot of forever chemicals but it erodes microplastics as it filters. It also sounds like you need a fairly special material to print it, not just your average plastics.
Something people can do to treat their water for some forever chemicals is using activated carbon filters. There are several types available from different residential water treatment companies.
I've been using a multi-stage RO filter for years. It used to be because one didn't know what was coming out of the pipe in the next gallon of water. Now it's because I know what's coming out of the pipe.
