Due to rising variety of outer car body panels, the potential of additive manufacturing in tool making is continuously increasing. A novel approach is hybrid-additive manufacturing of tool components using laser metal deposition (LMD). Numerical simulations can be used to analyze efficient scanning strategies and reduce process-related residual stresses and deformations. In this study, a finite-element-model for the LMD process is developed and validated within the software LS-DYNA. The mechanical material properties are required to create the material cards used in the simulation. Therefore cylindrical specimens for tensile tests are manufactured. A thermo-mechanical coupled simulation is performed to calculate thermal and mechanical behavior of the part during deposition. After validation, the influence of different scanning strategies on stress formation is analyzed by simulations. Finally, the validated simulation model is used for the calculation of a cutting tool to demonstrate the feasibility of applying the simulation concept to a serial component.
