This is the process in a nutshell. A wax pattern tree is made of the complex parts. The tree is covered in a hard ceramic slurry which is left to dry. The wax is then melted out before molten metal is poured in to fill the cavities left. After the metal has cooled the hardened slurry is broken off and the metal parts are removed from the tree and cleaned up.
