smells of bikesAnyone else out there doing sand casting or lost wax/lost PLA casting?
I'm having some ideas about using something like a laminar flow gating system, smooth spiral sprues from the pour basin down to the bottom of the mold, and am wondering if anyone else has tried this. There are some interesting research papers about it.

I think if I try to cast something jt could be defined "lost time casting".
Anyway the idea of the "bottom-up" pouring sounds promising to avoid bubbles.
