Digital lost wax for metal casting

Lost wax for bronze casting

The digital 3D model is rendered in wax, then the lost wax technique is used to make the metal object. The process is used extensively in rapid prototyping, jewelry making and bronze sculpture art. Different options are available for turning the 3D model into a wax model: 1.) liquid wax is printed, or 2.) the object is carved/milled out of a solid wax block (subtractive).
