[EMS Discuss] PROPOSAL - metalcasting facility

[Kassandra Kaplan]

That exactly how it's done. Print, attach vents and pour holes( if not modeled ), slurry, pack in sand, melt/burn out the pla, melt/pour aluminum, and break out of the mold.

Would love to try it sometime.  Some people in Corvallis trying to do the same thing.  They just got a solidoodle to help them to that end.

Kass and I talked about this a while ago, she mentioned that lost-PLA is a way to use a 3d printer to produce a source object (then presumably dipped in slurry and heated until the PLA is gone before metal is poured into hollow mold).
