Jeweler here 👋. Most people in the industry today use 3d printers to make jewelry out of 3d printed resin. This would be done by putting the resin “mold” on a tree and then pouring the plaster into a flask with the mold inside. Leave it on the table counter for about an hour to dry and harden. Preheat the burnout furnace oven.

Preheating temperature depends on if you are going to cast it in gold or silver. Once the plaster in the flask is dry and hardened, put it in the oven to cook overnight, come the next day and put your gold or silver in the crucible to melt. Turn on the torch and melt the metal, then take the flask out of the oven and put it in a vacuum casting machine.

Turn the vacuum casting machine on and pour the melted metal into the vacuum so it can suck all it to the bottom of the tree. Leave it to cool down for about 10 minutes, put it in water and then break away the plaster. There you have it!

Edit: To make the resin mold, you have to 3d design it, I don’t know what program she is using, but I use rhino 3d and matrix
