This is a pretty cool concept for hobbyist with a 3d printer who wants one off metal parts. Sure, you can always cast… but it’s not easy.
There is a similar way to do this casting with infusion and sintering using metal powder infused FTP printer filament. It shrinks down a bit more than this freeze casting sintering I think but it skips the slurry/freezing step of freeze casting.

Can you elaborate on how a hobbyist with a 3d printer could use this process?

I'm guessing just 3d print something with this metal infused filament then sinter it and the plastic burns out.
Edit: Oh if you mean freeze casting you would print a mould, fill it with slurry, freeze, dry the casting somehow, then sinter.

I'm not sure why this has to be specified more than once. Is a "slurry" meaningfully different enough from a "suspension" or "solution" such that it needs to be specified each time?

It's a carrier medium... and it's pretty thick. I would have just committed to "slurry".
Sandy water at the beach that looks a bit brown? Suspension.
Mining run off that looks like soup and coats everything? Slurry.
What's the Half & Half between milk and cream but for tweaky techniques for fabrication? Slurspension?
