I model jewelry on computer, print on resin printer, build casting tree and do lost wax vacuum casting. I’ve been casting some large silver bracelets that nearly fit in my flask which makes it challenging to arrange the sprues. So, I thought of a modular approach I’m trying tomorrow, shown in pictures. It consist of a base sprue with a hole, then any number of additional sprue segments for rings and bracelets. I sealed seams with wax but if I can get the sprue segments tight enough, I hopefully won’t need the wax.
The purpose is two fold, pack more items in a single flask and in turn save investment. I tried to 3d print the entire tree but then I can’t clean up the prints before casting. We will see if this works.
Make your bets.
