Making cheap lost foam casting slurry

Taking simple Ingredients from around the house we create the slurry to do lost foam casting. This is much like investment casting but easier for the DIYer and with care and safety we can turn out a surprisingly nice casting in the foundry.

if you take a scraper and wipe the the bucket wall above the slurry line clean after each use, it will drastically reduce the propensity for the dried stuff to fall into and create chunks the slurry. Best, Kelly

I thought this video was for lost foam, not plaster....

And you can fill this with molten aluminum with no major issues? I was under the impression a slurry had to be some unusual refractory material only special gods can acquire. This is awesome! I know nothing of this, BTW, as I have never attempted it. It was only an impression, so looking forward to watching your second part and learning from this!

Anyone who has done this, what kind of surface finish/detail are you able to acheive with the watered down joint compound? Currently testing this a few ways going looking for the most immaculate part casting with a lost pla or lost wax casting. Have a few different mixes drying with added flour silica, added waterglass. The joint compound seems to hold up pretty well but i need perfect for a 1 tine cast of a precision mold😂 asking alot i know and am too cheap to buy a ceramic slurry so.. help/experience/tips tricks appreciates

Can’t wait to see more of this. I’m new to casting but lost foam seems to consistently make clean parts. I’m excited to dry this myself.

Just curious if that mixture is ready for the casting process? How long would it take before it gets sturdy?

Looks like you've been busy

You could pull a vacuum on the bucket to get the air out like they do on epoxy pours.

Thank you for showing this!

Consistency of gravy. 👍

Good show. Looking forward to seeing those big ones cast. Cheers

Get a rigid mixing drill and if it shits out you can return it for the warranty.

[@theMassiveEffect]

i do wonder if that mix would work with lost pla casting

[@deucedeuce1572]

The shells don't dissolve in water once they're done? ...and the water content don't make them crack when dried or heated? I've thought about trying to use dry wall compound myself, but always discounted it, because I assumed it wouldn't work.

Dear Mr. Wright,
