For creating jewelry in gold, silver, bronze, copper and brass, we use Lost-Wax Printing and Casting. This technology builds upon modern 3D printing technology as well as traditional metal casting.
It all starts with 3D printing your 3D model in wax. The 3D printer uses a wax-like resin as printing material. Next, one or more wax sprues will be attached to your model. Then your model will be attached by the sprue to a wax ‘tree’, together with several other models. The tree is then placed in a flask and covered in a fine plaster. When the plaster solidifies, it forms the mold for casting the metal. The plaster mold is then put in an oven and heated for several hours to the point where the wax is completely burned out.
