The lost wax casting process is when a model is put into a steel flask that produces a mold when the wax is burned off. The mold that is created by this process is then filled with the precious metal material used to create the jewelry piece. With jewelry designs that use computer-aided design (CAD) to design the model of the jewelry piece, the model that is used for the lost-wax casting process is one that has been 3D printed.
