Abstract: A process for producing an object having at least two component parts (3, 4) which can move relative to one another is proposed. This involves preparing geometrical data of the entire object for a rapid prototyping process, with a predetermined minimum spacing between the moving parts being taken into consideration. According to the predetermined geometrical data, a first material as support material and a second material as material for the component parts are applied in layers, the support material filling gaps including those constituting the minimum spacing between the respective material for the component parts. Following completion of the layered construction, the support material is removed.
