Freeze-Casting
en.wikipedia.orgThis 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 can’t say I’ve done it, just in theory you could print the model to pore on the slurry, directionally freeze it, freeze dry it, and then sinter it… quite a process and may require some specialized tools so I mentioned the FDM infused filament since it’s a similar concept with only a kiln needed.

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.
