Warhammer Fantasy, 40000 and Lord of the Rings miniatures are made by the Citadel group. They employ designers, who create either modeling putty or CAD mock-ups of the models. These are then cast into Miniatures, in either plastic, or a metal alloy. They are typically cast in sprues, to keep related parts together. It is then the role of the player, to piece the models together with glue, and paint them.
