I went through this thread. And I see the interest of the process.
I wondering if it would not be possible to get the same result with a plasma torch projecting liquid bronze with high speed on the inner part of a ceramic mold just like paint.
you said: "With this process i could complete a chess set from the rubber mold to finished bronze in 3 days and give it to a scientist when I was done and he or she would say it's cast. how is that possible to take a three week process and shrink it down two three days."
my answer is that provided I have the original chess set, I bet I can do the same work in three or four days too, using traditionnal ceramic shell casting. It is very easy in fact. And with the original scale. I have my own way.
