    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.

    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?

      A slurry is a type of suspension, I guess.
