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.

> solution or slurry

> suspension or slurry

> solution or slurry

> suspension or slurry

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?
