Rapid Tooling technologies are innovative manufacturing technologies allowing rapid and fully automated production of tools. Based on the existing Laminated Object Modelling (LOM) Rapid Prototyping (RP) technique, this doctoral thesis enhances the used material system as well as the manufacturing process to be able to produce load optimised tools. To increase the mechanical strength of the paper built LOM-tools an additional process step of the complete infiltration with epoxy resin is added. The characteristic values needed for the material description are determined by experimental tests. The RP characteristic layered structure requires the determination of the mechanical and tribological parameters in relation to the stress direction. Based on these anisotropic material characteristics the modelling of the metal forming process is executed by volume-meshed tools. Thus, a prediction of the formability, influenced by the deformation of the stressed tool, is possible.
